Abstract

The introduction of soybean aphid and soybean rust to North America led to numerous insecticides and fungicides becoming available for use on soybean. Frequent outbreaks of soybean aphid along with reports of increased yields due to fungicide application, even in the absence of foliar disease, has resulted in widespread use of tank mixes. The popularity of tank mixes (a co-application of insecticide and fungicide) as a management tool is increasing. Many pest management programs that recommend this strategy apply pesticides based on soybean growth stage.
