How to Get the Most Out of Spring Soil Sampling


Dan Kaiser, Extension Nutrient Management Specialist

The purpose of a soil test is to provide guidance in fertilizer application. Soil test results help you fine-tune your nutrient management practices based on real data, and ultimately protect your bottom line. However, there are a few key components to getting the soil test right.

Respirator Fit Testing Opportunities

Willmar, Fargo/Moorhead, and Crookston

Are you planning to use a product that requires a respirator this year (some examples include *Engenia™ , Lorsban™ -4e and Advanced, or Dipel™ Pro DF)? Fit testing is mandated by the Worker Protection Standard and the labels. It is also critical for ensuring that your respirator will protect you from exposure.

Managing Insecticide-Resistant Soybean Aphids: A New Multi-State Extension Publication

By Robert Koch (Assistant Professor & Extension Entomologist)

Insecticide-resistant soybean aphids have emerged as a new challenge to growers in Minnesota and neighboring states. In a new Extension publication, we suggest strategies for managing soybean aphids resistant to pyrethroid insecticides. A few key points for managing insecticide-resistant aphids are:
  1. Apply insecticides only when needed (i.e., scout soybean fields and use the economic threshold of 250 aphids/plant to determine when to apply insecticides), 
  2. Apply insecticides correctly (i.e., proper rates, good coverage, etc.) and check efficacy of insecticide 3-5 days after application, and 
  3. Alternate insecticide groups if fields need to be retreated. 

To assist with alternation (rotation) of insecticides, we summarize the different insecticides (and their corresponding insecticide groups) available for soybean aphid management. This new publication, entitled “Management of Insecticide-Resistant Soybean Aphids,” is available here: https://www.ag.ndsu.edu/publications/crops/management-of-insecticide-resistant-soybean-aphids

Should you use an in-furrow starter this year?


Should you apply an in-furrow starter fertilizer this year? Starter fertilizer can mean more costs, but can have huge benefits in certain operations. Crop rotation, soil type, tillage and application practices all play important roles in your decision to use a starter. Soil Scientist Jeff Vetsch and Extension Nutrient Management Specialist Dan Kaiser share their advice in a recent article in The Farmer.

Dicamba: tips for complying with buffer and spray drift requirements in 2018


Buffers are one important tool in reducing off-target movement of pesticides to neighboring crops and sensitive areas. Given the high number of dicamba off-site movement complaints in 2017, applicators need to take special care this year. The following guidelines help to explain the label-mandated dicamba buffer requirements for 2018.

Aphid-destroying wasps found throughout much of Minnesota: Seeking fields for 2018 wasp survey

By Jonathan Dregni (Graduate Student), Robert Koch (Assistant Professor & Extension Entomologist), and George Heimpel (Professor), Department of Entomology, University of Minnesota

Cooperators are needed for a U of MN survey of soybean field for a parasitic wasp of soybean aphid.  These wasps (called Aphelinus certus), which do not sting people, are working to prevent soybean aphid outbreaks. First detected in 2005, this parasitic wasp spread quickly across the North American range of soybean aphid, arriving in Minnesota in 2011. Larvae of the wasp live inside and eventually kill the aphids leaving dark-colored “mummies”, which look like inflated black aphids attached to soybean leaves and stems. Adult wasps emerge from the mummies, mate, and immediately begin laying eggs in nearby aphids. Many generations of this wasp occur over the course of the summer.

Webinar on minimizing spray drift

As off-target movement of pesticides becomes an increasingly important topic, we need as many tools as possible to reduce drift. The EPA office of Pesticide Programs will host a webinar on March 15 about strategies for minimizing spray drift. Dr. Greg Kruger, a weed scientist and application technology specialist at the University of Nebraska, Lincoln, will lead the webinar.

The webinar will run from 10:30am-12pm CDT.
