U of MN Field Crop Trials Bulletin Available

By Lizabeth Stahl

The University of MN Field Crop Trials Bulletin is now available in print and electronic forms. The new publication, dated January 2013, provides results from U of MN trials conducted in 2012 across the state. The varieties tested are from both public and private breeding programs and include U of MN developed forage, grain, and oilseed crop varieties.

Plant varieties tested include alfalfa, barley, birdsfoot trefoil, canola, corn for grain, corn for silage, oat, soybeans, spring wheat, and winter wheat. Trials were conducted at Research and Outreach Centers across the state at St. Paul, Becker, Crookston, Grand Rapids, Lamberton, Morris, Rosemount and Waseca, and also in farmer's fields. Results are from replicated trials conducted at several locations, which allows growers to evaluate how varieties performed across various environments, while accounting for variability within a location and across locations.
The variety trials bulletin is available online through the Minnesota Agricultural Experiment Station website at http://www.maes.umn.edu/.

Sauk Centre Hay Auctions Sept. Oct. 2012

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties
   This is the first posting of my summaries of the Sauk Centre Hay Auction for the 2012-13 season. The first sale in September was the largest of 4 sales held now. It could be that buyers and sellers got busy with harvest after the first sale.
   Look at averages carefully, especially when they cover a small number of loads. Also take a close look a situations where there might be an odd load in the bunch. Large Round Alfalfa RFV 151-175 on October 18 is an example of this. There were 4 loads listed at $210 to $240 and one load listed at $40 per ton. Sometimes this is a load that is in poor physical condition, even though it tested in the range. Sometimes it is a data error. For me in this case, it doesn't make sense to include it in the average.
   I will list the postings here and some other sources of hay market information are listed in the extra reading.

Tires, Traction, and Compaction Field Day: Videos Discussing Four Main Topics Now Available

In September, 2011, University of Minnesota Extension, partnered with NDSU Extension, brought you the Tires, Traction, and Compaction Field Day near Fergus Falls, MN. There are now four videos highlighting the key messages presented during the day. Each video takes you to the unique soil pits constructed for that day to illustrate soil structure and effects of equipment traffic on soils. Each video is under six minutes yet captures the field experience for those unable to attend. They represent a great refresher for the 200+ participants who were there.

Fall Nitrogen Application

By John Lamb, Extension Soil Scientist

This year the crops have matured early and harvest is moving ahead of normal.  With a large amount of the soybeans and corn coming out, thoughts are turning to getting fertilizer applied for next year's crop.  For phosphorus and potassium, there are very few problems with an early fall application.  These nutrients are not mobile in most soils. The only big concern with a broadcast application of P and K is getting the fertilizer incorporated into the soil so it is in a place for the plant roots to utilize them next spring.  Incorporation also reduces the chances of P and K being lost through erosion.

Watch For Potential Corn Ear Rots and Mycotoxins After Dry and Hot Weather in Parts of Minnesota

By Dean Malvick, Extension plant pathologist

Development of corn ear and kernel rots and associated mycotoxins in grain may have been favored by the dry and hot weather in some areas of Minnesota this summer. Although few problems with ear rots or mycotoxins seem to have been reported so far, only about 12% of corn was harvested in Minnesota as of September 16 and there is much grain to be harvested where potential problems may have occurred. Several different types of ear rots occur in Minnesota, but Aspergillus ear rot and Fusarium ear rot are of greatest concern because they produce mycotoxins and are favored by hot and dry conditions.

Tips for Planting Winter Wheat Late

The unusually warm summer this year now means that there are many acres that have been harvested that potentially could be planted to winter wheat. It appears that the lack of rainfall could be a deterrent to winter wheat planting, at least to getting it planted during an optimum period. Our current recommendations are to plant winter wheat in the northern half of Minnesota by the middle of September and the rest of the state by October 1st. Unfortunately, there does not appear to be any rain in the immediate forecast. Planting into dry soil and waiting for rain is a viable option. In this scenario, put the seed about an inch deep so that it will be able to emerge quickly once rainfall is received. Though seeds that just begin the germination process will vernalize (meet the necessary cold requirement to produce a spike in the summer), a much larger seedling typically has a better chance of overwintering and being more productive. In the last three years of our research, the early planted treatments have always been more productive than those planted later than optimal, though the difference was not always large, depending on the year and the variety grown. If the warm weather we are currently experiencing spills over into the October, however, there should be ample time to produce a productive seedling, even if rains delay a week or two more.

Performance problems surface again with Bt corn rootworm traits

By Ken Ostlie and Bruce Potter, University of Minnesota Extension

Bt-RW problem field with lodged corn
Bt-RW problem field with lodged corn

Calls over the last two weeks indicate Bt-RW trait performance problems may be expanding in scope. Field observations suggest corn rootworm populations have increased markedly in corn after corn fields since 2011; recent calls indicate a major expansion of the geography of performance problems into SC and WC Minnesota. Unfortunately the drought has masked the primary tip-off to severe corn rootworm injury—lodging. With injury largely completed and corn rootworm emergence peaking, now is the time to check fields for signs or symptoms of performance problems with your Bt-RW traits. Getting a handle on Bt trait performance is critical before making seed purchases for 2013. You may need to change your corn rootworm management strategy/strategies.

Small grains disease update

This year proved to be an interesting in more ways than one for the cereal crops in Minnesota. The mild winter and spring saw many growers planting their crops very early. However these same conditions conspired to give us early influxes of aphids carrying Barley yellow dwarf virus (BYDV). While this disease can always be found in low levels in wheat, barley and oats (characterized by yellowing and eventually drying of leaf edges originating for the leaf tip and progressing down towards the stem in wheat and barley and red to purple discoloration in oats), symptom severity this year was far more extreme in a lot of cases due to plants being infected at very early growth stages. This resulted in severe dwarfing and excessive tillering, something rarely, if ever, seen before in Minnesota.

Using Drought-Stressed Corn for Forage

By Lizabeth Stahl, Extension Educator - Crops

Drought conditions continue to intensify in areas across the state including Southwestern Minnesota. According to the July 24, 2012, U.S. Drought Monitor report, the southwest corner of the state is now rated in the "Severe" drought category. The western half and southern counties of the state are also rated as "Abnormally Dry" or in the "Moderate" to "Severe" drought categories, and throughout this area soil moisture levels are low. For example at the U of MN Southwest Research and Outreach Center in Lamberton, soil moisture levels are less than half the historic average for this time of year, and what moisture remains is almost all at a depth of more than 3 feet. In areas hardest hit by the drought, growers are assessing grain yield potential and if or when to harvest drought-stressed corn for forage.

Spider mites: some points to consider

From the University of Minnesota Extension Southeast Crop Connection newsletter

spider mites
Photo 1. Spider mites
Spider mites are the concern today. Symptoms have become more obvious in some fields, especially along field edges, drought pockets and drier area in the region. Is this a "tornado watch" or "warning"? A watch in most fields, but we have touchdown (warning), with damage in some (more drought stressed conditions). You need to scout now.

Crop revenues and costs resulting from drought

Don Nitchie, Extension educator, dnitchie@umn.edu

How quickly crop conditions have changed from the wet weather of May.

Extreme heat and lack of rainfall throughout June has resulted in USDA Crop reports having been dramatically revised to reflect deteriorating crop progress throughout the U.S. Corn Belt. At the moment, conditions appear not quite as severe in SW Minnesota as in other regions but, that could change soon. I hope it is for the better as the result of rainfall.

Dry conditions threatening to generally impact final yields across the U.S. Corn Belt have historically had significant impacts on "old crop" and "new crop" prices. We have certainly seen that in the last few weeks. If market demand for corn or soybeans remain the same and stocks are tight, a relatively small change in expected supply leads to a larger change in prices.

Relief spelled R-A-I-N for some

Dan Martens, Extension educator, marte011@umn.edu

Rain during the last week to 10 days provided some relief to some crops through central Minnesota in various amounts. Crops are at a lot of different stages. Some scorched corn crop may not benefit much from rain anymore. Pollination may have been hurt for some corn. There is a large amount of corn, soybeans and hay crops that will benefit significantly from recent rains.

Small Grains Disease Update

Temperatures are set to be high again this week with maximum temperatures forecasted from the high 80s to mid 90s. Humidity will be lower than we have seen in the past week. Most of the wheat crop is now in the soft to hard dough stage of development.

With the warmer weather, stripe rust is finally entering the resting stage of its life cycle evident as black telial pustules on leaves. Leaf rust incidence is moving North and West through the state with the highest incidences (up to 100%) and severities (up to 30%) being reported in Otter Tail county.
Incidence of tan spot is on the increase as well - in some cases 100%,of affected - with low to moderate severity. This trend is likely to continue in the central and eastern parts of the state over the next few days.

Risk of leaf rust in the central and eastern part of the state will trend much higher in the next couple of days. The risk for tan spot remains high throughout the state.
Scab risk remains moderate to high in the north west of the state. Initial reports of scab infections have been confirmed, especially in the most northwestern portion of the State. This is the same area for which the risk model had shown a moderate risk for FHB 2 to 3 weeks ago. Incidence and severity are low at this point.

What is the next step this season in N management for corn?

John Lamb and Daniel Kaiser, Extension Soil Specialists

The corn is tasseling, we are praying for rain, and the week of the 4th of July was hot and miserable.  It must be time to think about evaluating this year's nitrogen management program and making decisions about next year's nitrogen needs.

Tuesday, July 10, 2012

Small Grains Disease Update

07/10/2012

Temperatures are set to be slightly cooler this week than last, and expected to stay in the low to mid 80s. Humidity will be lower than we have seen in the past week. Most of the wheat crop is now in the late milk early dough stage of development.

Stripe rust is still prevalent across the state. However weather conditions are now becoming favorable for development of leaf rust which is evident in the south and west of the state with severity ranging from moderate to severe. Sibley county being the worst affected at present. Septoria diseases have progressed with 100% of some fields affected with moderate to high severity.

Risk of leaf rust in the central and eastern part of the state will trend much higher in the next couple of days . The risk for tan spot remains high throughout the state. Scab risk remains moderate to high in the north west of the state.

Reports of fields with a unusual amount of dead heads with little or no grain have been reaching us. Incidences as high as 15-20% have been reported. We are sampling some of the worst fields to determine the exact cause or causes and will share those results as they become available.

Dry Conditions During Corn Pollination in Minnesota

By Jeff Coulter, Extension Corn Agronomist

Tassels became visible in early-planted corn fields around Minnesota at the beginning of last week, coinciding with unusually hot and continued dry weather. While some isolated areas in Minnesota received a little rain late last week, most did not.

This week, a large percentage of the corn in Minnesota will be pollinating. Although air temperatures across Minnesota during the next ten days are forecast to be near optimal for corn (mid- to upper 80s), there is little chance of rain during this time. How will these weather conditions affect the corn crop?


The critical period for avoiding stress in corn is during the two weeks before and two weeks after tassel emergence, with the most important time being about eight days after tassels emerge. Drought and heat stress around tassel emergence can affect the success of pollination and the number of kernels per ear.

Spider Mites in Soybeans


We've been getting calls about spider mites in soybeans, not surprising given our high temps and the dry conditions in some locations. As temps get into the 90's, spider mite reproduction and development rates increase significantly. Drought also exacerbates spider mite populations, and when drought conditions are relieved by rain, spider mite populations may not necessarily decrease. Consequently, even after drought conditions pass, best to continue scouting for spider mites damage.

Spider mites are tiny and only large females are visible to the naked eye (unless you've got really good eyesight!). The best way to see spider mites is to shake a plant over a piece of white paper - any moving pieces of dirt are likely spider mites... So to scout for something that small, it's best to look for damage. Spider mite damage will first appear as small yellow spots (stippling) on lower leaves. There is currently no solid treatment threshold in soybeans, but If stippling reaches mid-canopy leaves, a treatment is likely necessary. Pyrethroids may flare spider mite populations, spreading mites and increasing their populations.

A good source for information on spider mite biology, scouting and thresholds was prepared last year by Bruce Potter and Ken Ostlie and is available at:

http://www.extension.umn.edu/agriculture/soybean/pest/managing-two-spotted-spider-mites-on-soybeans/

Keep scouting!

Aphid Alert 2012 - Ian MacRae (UMN), Robert Koch (MDA)


The aphid monitoring network, Aphid Alert, lives again....

The network, which ran from 1997 through 2003, was designed to monitor the seasonal dynamics of aphid vectors of viral diseases of seed potatoes. The national epidemic of Potato Virus Y (PVY) has been increasingly impacting marketability of MN & ND seed potatoes. Vector control is an important part of PVY management, but is dependent upon a clear understanding of the spatial and temporal dynamics of vector populations. To provide this data to producers in MN and ND, we are re-establishing the Aphid Alert network.

Aphids have already been found in the Crookston location trap and in plots at the NWROC. It looks to be an early year!

Weekly results and updates can be found on:
aphidalert.blogspot.com

Small Grains Disease Update

Weather conditions have been getting steadily warmer over the last week, routinely in the mid-80s° F. This trend is set to continue over the next week with temperatures reaching the low 90s° F. This unusually dry and warm weather is having a direct impact on the range and severity of diseases and plants reactions to other stresses such as herbicide drift and drought. With the majority of wheat in the end of milk and into the early dough stage, many plants are clearly showing evidence of heat stress. This heat stress is exacerbating other diseases that are not normally prevalent.

Stripe rust is still very evident across the state with high severity on spring and winter wheat in to the mid canopy. A number of fungicides will give good control of stripe rust provided they are applied before symptoms are evident on the flag leaf. Fungicide application will not cure already visible or latent infections. Although the warm temperatures will slow stripe rust development, cooler night time temperatures and the chance of stormy precipitation, will allow this disease to continue. If generic Folicur, Prosaro or Caramba were already applied at Feekes 10.51 to suppress scab, you can expect sufficient control for the remainder of the growing season for stripe rust.

Septoria species are also becoming prevalent in the west central portion of the state with low - mid severity on 20-50% in the fields scouted. Evidence of wheat stem maggot is now appearing in the south-west of the state. Typical symptoms of damage caused by this insect are white or blasted heads which will produce no grain, while the rest of the plants looks normal. The head can easily be pulled from the plant to reveal the feeding damage.

Because of the weather, the risk of scab is likely to be very low over the next week. These same conditions are more conducive to stem rust and leaf rust may become more evident, especially in the southern part of the state.


Tall Off Types in Wheat.

Jochum Wiersma, Small Grains Specialist

Variable wheat height
Photo 1. Variable wheat height.
A fair number of spring wheat fields appear to be quite variable in plant height this season. Obviously varying degrees of drought stress can create height differences that are, in some instances rather striking (Photo 1). Differences in height, however, are more interspersed and without clear delineations and/or transitions as is the case in photo 1, it is probably not drought stress per se but one of three things:

  • a variety blend
  • a variety that is segregating for plant height
  • a variety that suffers from a genetics anomaly that results in a chromosome being lost across generations.

Monday, June 25, 2012

Small Grains Disease Update

While a 11-plus inch deluge made for national headlines in Duluth, much smaller but timely rains have helped stave a worsening of the drought stress in parts of northwest Minnesota. Drought stress is pretty evident is many fields as evidenced by differences in plant height across the field. On June 19, the majority of northwest Minnesota is still rated to be in a moderate drought while a large portion of west central Minnesota is still considered abnormally dry. Timely rains will be needed to allow grainfill not to be impacted by drought as the crop needs nearly a 0.25 inch of water daily at the beginning of grainfill.

Update on Goss's Wilt in Minnesota

By Dean Malvick, Department of Plant Pathology

The fact that Goss's wilt is was a widespread corn disease in Minnesota in 2011 is broadly known. The question of how much Goss's wilt will develop in 2012 is dependent in part on field and weather conditions. As of June 13, 2012, Goss's wilt had been confirmed over the previous week in several counties in Iowa and Nebraska. Thus it could also start to appear soon in Minnesota. This article summarizes key points about this disease, including where it has been confirmed in Minnesota, factors that favor its development, and how to recognize it.

Thursday, June 14, 2012

Small Grains Disease Update

06/14/2012

The spring wheat in many parts of the state is now fully headed or pretty close to it. The drought stress has been partially abetted with some timely rains over the weekend. Yield potential, however, of the most drought stricken fields has been greatly reduced as tillers and lower leaves were aborted. This is very visible as the canopy opened up. Some of the worst field will likely not yield much over 35 to 40 bushels.

As far as diseases are concerned, these are some of our own observations and those of the scouts that are paid for through a grant of the Minnesota Wheat Research & Promotion Council. Tan spot is still the most prevalent disease, closely followed by stripe rust. Both diseases have progressed to the middle of the canopy, particularly on more susceptible varieties, as is the case for Faller and stripe rust

BYDV like symptomology can be readily found in barley, particular in the southern half of the state. Disconcerting in these cases is the high incidence and the severity; very seldom, if ever, have we seen such a widespread infection across fields, and the severe stunting. Fields have actually been abandoned and replanted with soybeans in the past week.

Now is the time to scout the fields to assess yield potential and the presence of any foliar diseases such as tan spot and leaf or stripe rust. With the increase in precipitation, disease risk models have, and will likely continue to trend higher, especially for the foliar diseases such as tan spot and stripe rust.

The decision to apply a fungicide at Feekes 10.51 will not be easy this year. Given the weather forecast for the next 5 to 7 days, we don't expect the risk models for FHB to increase dramatically. The decision therefore will hinge as much on the presence of foliar diseases as on the risk for FHB. The lower yield potential further complicates the matter.


Tuesday, June 5, 2012

Small Grains Disease Update

The Minnesota Wheat Research and Promotion Council funded a disease survey in small grains in 2012. This is a summary of what the scouts have found in the past few days:

The winter wheat is mostly at or just past anthesis is looking very good overall. The spring wheat is not far behind and is more variable. Drought stress is evident in the central and northern portions of the Red River Valley with the area around Crookston being the hardest hit by drought. Available soil moisture at the NWROC is between ~ 2.7 to 3.3 inches in the top 5 ft of three soils series that were sampled last week (or less than 25% of field capacity), with less than 0.5 inch in the top two feet of two of the three samples.

Crop Water Usage, Available Soil Moisture and Irrigation for Small Grains.

Jochum Wiersma, Small grains specialist

For high yields, small grains need 14 to 17 inches of water depending on weather conditions and length of growing season. The water used for optimum growth is a combination of stored soil moisture, rain and irrigation. Small grains require about six inches of water as a threshold for grain yield. Each additional inch of water will provide four to five bushels per acre. In deep well-drained soils, the roots of small grains will extract water to a depth of three feet. Small grains are most sensitive to water stress in the boot to flowering stage of growth.

Abundant Rainfall in Some Areas May Increase Soybean and Corn Seedling Disease

By Dean Malvick

With most of the soybean and corn crop emerged and growing across Minnesota - it is a good time to assess fields for seedling disease problems and the potential benefits or failures of seed treatments. The recent fluctuating temperatures and abundant rainfall that resulted in surplus topsoil moisture in about 21% of the state last week (USDA-NASS data) have created good conditions for seedling diseases and root infection by a complex mix of pathogens in many fields. Scattered problems with seedling diseases have been reported.

Seedling infection can result in dead plants before or after emergence, stunted and discolored plants, wilting, and complete or partially rotted and discolored roots. The problems often occur in a circular or random pattern in the field. Seedling infection can also lead to damage that may not be seen until mid to late summer, as is common with Phytophthora rot and sudden death syndrome. Disease is just one of many stresses that seedlings are encountering in fields. Close inspection and thorough diagnosis are often required to accurately identify the cause.

Freeze injury in small grains

Jochum Wiersma, Small grains specialist

The last two mornings thermometers have dipped below 32°F in many places across Northwest Minnesota. Unlike the freezing temperatures we endured in April, these lows may have actually caused some damage as most fields are now at or past the jointing stage. Kansas State University has published an excellent bulletin about freeze injury in wheat that describes in detail what the damage looks like and what the yield impact can be. Simply follow this link: Spring Freeze Injury to Kansas Wheat

Understand that any freeze injury is probably localized to sheltered and low lying areas. You should also now that damage to the growing point may not be evident immediately. Leaf tissue that is damaged should show symptoms after a day or two.

Small Grains Disease Update

05/31/2012

Winter and the earliest spring wheat fields are heading across the State. While producers in the southern half of the State comment that their winter and spring wheat has never looked this good, the northwest part of the State suffered enough drought stress to impact the yield potential of the spring and winter wheat crops. The drought and last week's heat caused tillers to be aborted and crop phenology to advance rapidly, with some field moving from jointing to having the flag leaf fully emerged in just over a week. A few initial counts of the number spikelets per spike were disappointing.

There are confirmed reports of stripe rust across the state but there are no confirmed cases of leaf rust to date. More details scouting reports will be available as of next Monday morning.

Now is the time to scout the fields to assess yield potential and the presence of any foliar diseases such as tan spot and leaf or stripe rust. Keep an eye on the weather forecast and the disease forecasting models to determine the risk for Fusarium head blight to decide whether an application at anthesis is warranted.

Scouting Alfalfa Fields for Nutrient Deficiencies

By Daniel Kaiser, Extension Nutrient Management Specialist

The dry conditions in March and April have given way to extremely wet areas in some parts of Minnesota.  Since alfalfa stands got an early start this year there were a few concerns popping up early in the southeastern part of the state on areas of fields yellowing.  While there may have been some effects due to the cool weather in April a couple of nutrient could be of concern.

Weather conditions have been extremely variable around the state of Minnesota this year. While some areas have experienced near record rainfalls others have still been in the midst of a drought. These differences have brought some interesting questions regarding management of potassium and soil testing in the midst of dry soil conditions.

Dry soil conditions can be challenging for crops to take up nutrients.  Elements such as phosphorus and potassium move to the plant roots via diffusion.  Diffusion is a process by which things move from areas of high concentration to areas of low concentration.  If you can think back to high school science if you open a bottle of ammonia at one end of the room over time you will smell the ammonia as it diffuses through the air.  That is a simplistic explanation of a more complex process in the soil.

When it rains, it pours! What is happening to my nitrogen?

John A. Lamb and Daniel E. Kaiser, Soil Fertility Specialists

Nitrogen is important for corn growth. This has been a concern on growers' minds since March. First concern was with the poor tillage conditions last fall. Did the nitrogen applied stay in the soil. We attempted to answer that question in a March 18 Crop News. At the time of that E-news, drought was the weather condition on everyone's mind. Now with the record rainfalls, there are concerns if nitrogen has been lost to leaching or denitrification.

Volunteer Corn - An Issue in Corn and Soybean

By Liz Stahl and Jeff Coulter

Growers are finding high populations of volunteer corn in their fields this spring. Factors likely contributing to this include lodging in many fields last fall due to poor stalk quality and drought conditions, and higher harvest losses due to low grain moisture at harvest. Other factors that can lead to high populations of volunteer corn the following year include storm damage and ear droppage. The question arises: When are populations of volunteer corn high enough to warrant control?

Central MN Alfalfa Harvest Alert Data - May 21, 2012

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties
UPDATED May 22 5:30 p.m.
The link listed here provided Central MN Alfalfa Harvest Alert Scissors-Cut data obtained through May 21. Additional Information might be added to this report on May 23 later in the afternoon or evening. If so it will be edited here at this link. We will sample again on Thursday Morning, weather permitting.

It looks like finding a WEATHER opportunity may be the primary decision factor for a lot of the hay crop in this area now milk cow quality hay. There are some fields yet that are just starting to show some bud development and might have a little time to grow yet.

PAST HAIL. Good news for hailed off field on May 1 north of Albany. It is a very nice looking stand of 12 inch alfalfa now. Nearly every stem was broken at 3 to 7 inches by the hail.

Remember, for scissors-cut sampling, we like to have 3-4 samples that are 3 or 4 days apart to establish a trend line to gain more confidence in the numbers.

Not all Yellows are Created Equal (or, more correctly, not all yellows have an equal creation...)

Ian MacRae (UMN), Jochum Wiersma (UMN), Janet Knodel (NDSU), and Bruce Potter (UMN)

Leafhopper populations are increasing in the northern RRV. Fields which held low numbers on Friday have significantly increased populations this week. These are all winged adults and so are likely the populations from the southern part of the state that are migrating north. We don't have any data on what impact on yield these higher populations of leafhoppers may have on small grains but sap-feeding leafhoppers generally don't impact yield. Having said that, leafhopper populations in typical years are much lower; in dry conditions, sap feeders have been known to exacerbate drought stress. Generally, leafhoppers are more important as vectors of the disease, Aster Yellows (AY). Caused by a phytoplasm, AY can infect wheat, and under the right conditions cause yield loss. Symptoms show up a couple of weeks after infection by the leafhopper and include yellowing of leaves, often accompanied with reddish or purple coloration (similar to BYDV).

May 17 2012 Alfalfa Harvest Alert Data - Central MN

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties
UPDATED MAY 18 9 PM
The link listed here provides Central MN Alfalfa Harvest Alert Scissors-Cut and PEAQ data obtained as of May 17. I expect to get a few more lab reports back on Friday and will aim to update the document posted at the link listed here sometime later Friday afternoon.

More buds - and more harvest decisions. As fields appear to meet harvest goals, farmers are making harvest decisions.

Remember, for scissors-cut sampling, we'd like to have 3-4 samples that are 3-4 days apart to establish a trend line to gain more confidence in the numbers. Thinking about a trend line takes out some of the "bounce" we see sometimes from one sample to the next.

Alfalfa Harvest Alert Data 2012 05 17.pdf

Check the notes at the end of the report for some discussion about why we might see better RFV in some fields this year. We'll find out in the feed bunk and for dairy herds in what cows are able to do with it.

CORN EMERGENCE - On another topic, we've had some calls in central MN this week about problems with corn emergence, mainly due to heavy rains around May 1 and 6. One key point to remember is that for corn that starts to leaf out underground, those plants will likely NOT make it to the surface. For some discussion about evaluating stands do a website search for "Minnesota Extension Corn Emergence" or go direct to:
Evaluating corn stands (2002)

Please continue to have a safe spring work season, hay harvest, and other things you enjoy in the spring.

Update on Aster Leafhoppers in Wheat

by Ian MacRae, Jan Knodel, Bruce Potter, Jochum Wiersma

High populations of Aster Leafhopper (also called 6-spotted Leafhopper) have been reported in small grains over the past couple of weeks. Starting in the south but now spreading to northern MN and ND. Aster Leafhoppers are greyish leafhoppers; the adults have clear wings and 6 spots between the compound eyes (Figure 1). Other than their coloration, the adults and nymphs both very much resemble potato leafhopper. The leafhopper uses it's piercing sucking mouthparts to feed on the plant's sap. The damage caused by Aster Leafhopper feeding is more localized than that produced by potato leafhopper. Feeding may produce localized necrosis or stippling (Figure 2), however, damage is much less than that caused by the Potato Leafhopper.

Alfalfa Hail Damage and Management Decisions

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties

Hail did some damage to alfalfa fields as well as automobiles and homes on Tuesday afternoon and evening on May 1 at places  from out toward Padua in western Stearns County to Albany. In some fields nearly all stems in established alfalfa were broken as stripped of leaves. These will need to start again with new shoots from the crown. In new emerged alfalfa seedlings, stems broken below the leaves are done. I'll attach an article here written previously by Wisconsin Extension Specialist Dan Undersander that offers some discussions about decisions that might be made.

On Farm IDC Management Strip Trials

Daniel Kaiser, University of Minnesota Soil Fertility Specialist

Research on Iron Deficiency Chlorosis (IDC) has been identifying methods to manage the problem for soybeans. Since 2010 research has been conducted using strip trials within farmers' fields. Currently we are looking for a 5 acre area to conduct a field study looking at the effect of Soygreen and oat cover crops on areas of the field that range from no-IDC to severe IDC. Our goal is to determine the economic benefits of the treatments on varying IDC severity within fields planted with two soybean varieties with varying tolerances to IDC.

Small Grain Disease Forecast System and Disease Commentary Online

The 2012 growing season is well under way. The spring planting progress has been at a record pace, a consequence of a very dry fall and winter and a very warm March. Winter wheat has very little winter injury and stands are generally very good.

The winter wheat crop is at or near jointing and some of the earliest spring wheat fields are not far behind. This means that it is time to start scouting for early season tan spot.

To aid in your decision whether a fungicide is needed to control early season tan spot you can go to http://mawg.cropdisease.com to evaluate the risk that conditions are favorable for tan spot to develop. Make sure to select the model for tan spot in the left hand model.

An overview article of control of early season tan spot can be found here:
http://www.extension.umn.edu/b-assets/efans/cropnews/2010/05/early-season-tan-spot.html.

Be aware that tank mixing fungicide with certain herbicides can result in temporary crop injury. See here for details here http://www.plantmanagementnetwork.org/sub/cm/research/2011/mixing/ and http://www.extension.umn.edu/b-assets/efans/cropnews/2011/06/early-season-tan-spot-and-risk.html

Assessing fields for "pop up" starter fertilizer damage

Daniel Kaiser, Extension Soil Fertility Specialist

Dry fall and early spring soils have led to questions about starter fertilizer application this spring.  While that planting with starter in a dry seedbed can significantly increase the risks, the overall effect will not be known until after planting.  Assessing the situation after emergence will be the best way to determine if damage has occurred due to "pop-up" fertilizer application.  With some corn already planted and fertilizer decisions made there are a few key points to remember when dealing with starter fertilizers.

When is Early too Early?

Jochum Wiersma, Small grains specialist

The record breaking temperatures of the past week make it feel more like the middle of May than the middle of March. Obviously, as the fields look ready, the question arises whether this early is too early. With the very late start of 2010 and the disappointing wheat and barley yields that followed still fresh in memory, everyone understands that early planting is paramount. What are the risks of planting too early? Is there such a thing as too early for seeding wheat and other cool season grasses?

What's Manure Worth?

UMN Extension has developed a new web-based calculator to determine the value of manure

William F. Lazarus - Extension Economist, Jose A. Hernandez - Extension Educator, and Les Everett - Water Resources Center Education Coordinator. University of Minnesota - Extension

A new web-based tool developed by Dr. William F. Lazarus, Extension Economist and Professor in the Department of Applied Economics, is now available. The web-based calculator may be used to compare the economic value of manure from alternative manure application rates and methods. The value is based on crop nutrient needs for a specific field and crop rotation, fertilizer prices, manure hauling costs, manure type, and application method. In addition to assisting with management of current livestock and crop operations, the calculator can be useful in budgeting new facilities or evaluation of contract production through estimating the effect of manure and manure management on cash flow. The calculations can also assist crop and livestock producer estimate the value of manure that may be transferred or sold from one entity to another.

Sometimes a picture is worth a thousands words. This photo of the winter wheat variety trial on the Northwest Research & Outreach Center was taken on January 10, 2012 in the afternoon as temperatures were a balmy 39°F. The warm temperatures over the previous few days had melted the little snow we had in the surrounding fields. The winter wheat trial was still blanketed, thereby protecting the seedlings.
