Industry Task Force II on 2,4-D Research Data

There are 33 species of weeds in the USA that are resistant to many herbicides. 2,4-D effectively controls 25 of them.


There are 33 different weed species in the United States that are resistant to one or more herbicide mechanisms of action.

After more than 70 years of use, only 7 species of weed have become resistant to 2,4-D, leaving it as an effective tool for managing weeds resistant to other herbicides.
