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

As the most widely used of the phenoxy herbicides, 2,4-D plays an integral role in modern weed control.


2,4-D is a proven technology; effective, inexpensive, with vast amounts of supporting data and a history of being found to have no adverse effects on human or environmental health.

2,4-D keeps costs to farmers low and crop yields high, across multiple agricultural sectors.

2,4-D has been in use for 70 years, but only 7 species of weeds in the US have developed resistance. It is therefore an important tool in managing weeds resistant to other herbicides.

2,4-D has a wide range of important uses in other sectors; helping to maintain infrastructure and leisure spaces across the United States.

2,4-D Research Task Force’s Updated Study

The 2,4-D Research Task Force commissioned an update and expansion of the 1996 National Agricultural Pesticide Impact Assessment Program (NAPIAP) report "Biological and Economic Risk Assessment of Benefits Phenoxy Herbicides in the United States."

Leading experts, academics, and scientists from a wide range of disciplines contributed to the 14 chapters found in this website.
