Prevented plant: Considerations for corn and soybean

Liz Stahl, Extension educator and Phyllis Bongard, Content development and communications specialist

Farmers across parts of Minnesota are dealing with excessively wet conditions that have delayed crop planting. As wet conditions persist and final planting dates for crop insurance in Minnesota for corn (May 31 across southern Minnesota) and soybean (June 10) approach, farmers are faced with the decision of whether or not to plant some of their crop / take prevent plant, plant their planned crop late, or switch to a different crop. There are many factors to consider when making these decisions and each farmer will need to evaluate what options fit best with their operation and situation.

Farmers should be in contact with their insurance representative for more details on the rules of prevent plant, eligible acres, options and implications during the late planting period, any follow-up management requirements, and impacts on items such as insurance coverage and actual production his…

Delayed (Again) Soybean Planting in Minnesota

by Seth Naeve and David Nicolai

For the third year in a row, soybean planting is being seriously delayed by weather in Minnesota. Like with the previous couple of years, it's a slow-go across most of the state.

On Monday, May 20th, the USDA Minnesota Crop Progress Report indicated that 22% of Minnesota’s soybean crop was planted, four days behind 2018 and eleven days behind the five-year average.

 Averages being what they are, many parts of the state report that the rate of soybean planting has been highly variable depending on rain patterns and soil conditions. For example, soybean and corn planting are significantly behind in southwestern and western Minnesota, but close to normal for northwestern Minnesota. While south central Minnesota growers have made good progress to date for corn planting, soybean planting has lagged due to spring tillage and fertilizer applications. Many areas of southeastern and eastern Minnesota have received excessive rainfall in May which was als…

Get to know your soybean herbicide SOAs

Lisa Behnken, Ryan Miller, Fritz Breitenbach, and Jeffrey Gunsolus

The planting season is slowly underway and plans may be in place, but they may need to be adjusted if you haven’t matched the right herbicide to the weeds you have or if the weather makes it impossible to get all your preemergence herbicides on. First, you need to know which weeds are in your fields and whether they are resistant to certain herbicides or not. Then you should make sure you have chosen the right herbicide(s) to do the best job on those weeds. Understanding the effective sites of action (SOA) of herbicides is an important part of this process. In other words, which weeds will they control?

Unfortunately, the glyphosate era of weed control made chemical weed control too easy, as glyphosate provided effective broad spectrum control of many weeds in many different crops. Overreliance on glyphosate brought herbicide resistance and the “easy” era came to an end. During this less complicated era, it was…

Alfalfa Harvest Alert Information/ Hay Auction May

Nathan Drewitz, UMN Extension Educator for Stearns, Benton, and Morrison Counties. or (320) 968-5077

The Alfalfa Harvest Alert Project/ Scissor Cut project is now underway. The goal of this project is to alert alfalfa growers to start first crop harvest when the crop is at a level of quality and yield potential that meets their specific needs.

Gopher Coffee Shop Podcast: Corn planting and the cool wet spring

Gopher Coffee Shop Podcast#2: Corn planting and the cool, wet spring

In this installment of the Gopher Coffee Shop podcast, Extension Educators Ryan Miller and Brad Carlson sit down with Dr. Jeff Coulter, Extension corn systems agronomist, to talk a little bit about the cool wet spring and its impact on corn planting and production. We discuss delayed corn planting, corn relative maturity, GDUs, corn growth and development, and tools for predicting corn growth based on historical climate data. Enjoy!

Pest alert: Black cutworm

Bruce Potter, Integrated pest management specialist

This has been an active spring for black cutworm (BCW) flights into MN. Pheromone trap captures indicating that moth flights are large enough to pose risk to crops have occurred through the past few weeks and are continuing. The southern tiers of counties have seen the most activity but traps located in more northern areas have seen issues as well.

The NWS precipitation forecast shows conditions likely favorable for more insect migration from the south. Another influx of BCW moths with these systems is likely. Other migrant crop pests including true armyworm, potato leafhopper and cereal aphids may show as well.

Unfortunately, these immigration events coincide with a late planting season in much of Minnesota, which increases the risk of economic injury to crop seedlings.  Based on this year's pheromone trap captures, there is an increased risk, but not certainty, for black cutworm damage.

Don't forget to look for cutworm leaf…

Gopher Coffee Shop Podcast: Launch of new crop production series

Gopher Coffee Shop Podcast#1 Launch of new crop production series

University of Minnesota Extension is launching a new podcast series for farmers called “The Gopher Coffee Shop.” The podcast is hosted by Extension Educators Brad Carlson and Ryan Miller, and will cover a wide range of topics related to crop production and related issues. The format of The Gopher Coffee Shop will be less formal and more conversational than many of the other U of M Extension podcast offerings, and will feature a wide range of guests from within and external to the University.
