What is 2,4-D?

The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is a selective, systemic, and plant growth regulator herbicide used for post-emergent control of weeds in corn, soybeans, small grains, sorghum, etc. in Minnesota. It can also be used for weed control in turf and lawns, forestry sites, and aquatic sites. 2,4-D is one of the top selling herbicides in Minnesota.

2,4-D is a volatile chemical that can damage non-target plant species through spray drift and/or volatilization (vapor drift). In 2014, the United States Department of Agriculture deregulated 2,4-D tolerant (Enlist) corn and soybeans. The United States Environmental Protection Agency has approved two new 2,4-D products, Enlist One and Enlist Duo, for use on Enlist crops.
