Insecticide has developed resistance in soybean aphids in the upper Midwest and managing insecticide resistance can be used with the Integrated Pest Management approach.

Understanding potassium’s role as an essential plant nutrient is critical to alleviating some emerging crop production issues.

A survey found soybean pollen was found in nearly half of honey samples, a strong indication bees are foraging in soybean fields, says Ohio State University Extension.

North Dakota State University Extension tackles the question of soybean aphid economic thresholds, and what growers should do based on past research and demonstration plot results.

Iowa State University Extension shares the results from its 3-year study that looked at soybean varieties with resistance to soybean cyst nematode and soybean aphid.

The 2 weeks before senescence can provide an opportunity to look into problem areas of fields and determine what may have caused challenges during the growing season.

By now we all should be familiar with the soybean aphid threshold of a rising population of 250 aphids per plant — but keep in mind that this number is the action threshold, not the economic injury level at which soybean aphid causes yield loss.

University of Minnesota Extension reminds grower to consider the potential development of insecticide resistance when treating soybean fields a second or third time.

Soybean aphid population growth can be quite rapid, so regular monitoring of populations is key to effective management, says University of Nebraska Extension.
