Soybean producers in Indiana frequently apply foliar chemicals to soybean with the goal of increasing yield. These chemicals, which include herbicides, fungicides, insecticides and foliar fertilizers, are often applied simultaneously to minimize trips made across the field. Each of these chemicals can improve soybean yields under certain conditions, however, the impact of co-applications on individual product efficacy and plant health is not well understood.

The overall goal of this project is to understand the effects of chemical co-applications on product efficacy, soybean yield and economic return for soybeans. The researchers will also determine how these types of applications...
