What do grasshoppers in small grains fields have to do with soybean?

Grasshoppers have reached treatment threshold population densities in some small grains fields in northwest Minnesota. In some fields this treatment threshold has been reached twice this year.

As drought-stressed small grains begin to mature and harvest begins, these insects will be looking for a new food source and may decide to move into neighboring soybean fields. 

UMN Extension has a webpage devoted to how best to scout for and determine whether grasshoppers population densities or feeding injury have reached a treatment threshold.
