Small Grains Disease Update 06/27/13

It may have taken some time to get in to the fields this year, but the small grains crops are now roaring away in the warmer weather. The earliest seeded fields are rapidly approaching heading and with that decisions about whether to use fungicide at anthesis are now front and center.

Reduce Risk of "Fallow Syndrome" with a Cover Crop

By Lizabeth Stahl and Jill Sackett, Extension Educators

The challenging spring of 2013 resulted in wide-spread planting delays across the state and a significant amount of acres that remain unplanted at this time.  If the decision has been made to take the "prevented planting" option for insurance purposes, the question remains about what to do with these acres.  Leaving the ground bare greatly increases the risk of not only soil erosion, but also the risk of "Fallow Syndrome" the following year.

Late Planted Forage Crop Options

by Dan Martens, Stearns-Benton-Morrison Counties

Some farmers have been still trying to plant corn for silage or other forage crops to meet feed needs for dairy and beef cattle. Recent rain has made a mess of these efforts again recently. One of the more recent field trials done to look at late planted forage crop options was done in Pelican Rapids and Rosemount in 2002 and 2003. I am posting a report of that study here.

When it rains, it pours! What is happening to my nitrogen? v 2.0

By Daniel Kaiser and John Lamb, Extension Soil Fertility Specialists

Many of our earlier planted fields in Minnesota have been exhibiting some significant variation in plant growth and yellowing this spring.  Our conditions in May and early June have been less than favorable for corn growth and for the release of nutrients from organic matter.  Due to the heavy rains nitrogen loss is being increasingly questioned and the decision of whether to side-dress or not will need to be made sooner or later.  There are a few considerations to make when deciding if more nitrogen should be applied.

Soybean aphids found on soybean in southeast Minnesota

By Robert Koch, Extension Entomologist

On June 11, 2013, we found soybean aphids on soybean at the Rosemount Research and Outreach Center near Rosemount, MN. Not many beans were out of the ground there, but in the two fields we sampled, we found aphids. We sampled one commercial soybean field at the VC growth stage (unifoliate leaves unfolded) and found 7.5% of plants infested with 1 to 9 aphids on each infested plant. The other field we sampled was a small plot trial, also at the VC growth stage, and had 10% of plants infested with 2 to 3 aphids on each plant.

Volunteer Corn: It's More Than a Weed Control Issue

By Lizabeth Stahl, Extension Educator - Crops

Volunteer corn has become one of the more prevalent weeds in fields across the Midwest. Conditions experienced in 2012, however, have combined to create almost a perfect storm in some fields for potentially high volunteer corn populations in 2013.

Snow, rain, mud, now what?

crop news late plant  pic 4.jpg

The weather has put us in a bind. Significant amounts of planting have yet to be completed, which has led to questions on the "correct" course of action. There will be no one "correct" course of action and with fields unsuitable for planting and more rain in the forecast there will be no easy decisions. One choice could be to utilize prevented planting, a choice that is appropriate for some and will lead to many other decisions to be made. A second option is to switch corn acres to soybeans; this may also be a wise and appropriate decision for some acres. Remember when planting soybeans after June 10th it is generally recommended to drop 0.5 RM from your typical full season varieties. The final choice is to stay the course and plant corn, a perfectly viable option for some acres.
