Commodities Survey


 

A number of invasive insects and pathogens threaten commodities in Minnesota and could cause problems for production and export if they were to become established here. The Minnesota Department of Agriculture (MDA), along with partners at the USDA and the University of Minnesota, conduct an annual review of invasive species that pose the greatest threat to crops in Minnesota and focus survey efforts accordingly.

Commodity crop surveys are conducted June through August and all of the primary agricultural production areas of Minnesota are included. The following organisms are the focus of surveys in progress during 2016:

Soybeans
