The National Corn Growers Association has joined a project to modernize the pesticide drift model software known as AGDISP. The “Agricultural Dispersion” software was developed by the U.S. Forest Service in the 1980s and is used by the EPA to model the movement of spray in the environment after it is released from a sprayer. The modernization project will update and improve AGDISP software. A modernized version will more accurately estimate off-target spray movement for all types of pesticide applications when the EPA conducts ecological, endangered species, and human health risk assessments. It will also allow the drift reduction benefits offered by new application technologies and techniques to be recognized by the EPA. That should result in less restrictive and more flexible application requirements on labels. The AGDISP software will also be available to the public and open source, which means companies developing new application technologies can incorporate it into their research.
