[11] Surfactants are used in herbicide formulations as wetting agents, to maximize coverage and aid penetration of the herbicide(s) through plant leaves. As agricultural spray adjuvants, surfactants may be pre-mixed into commercial ...
The Pesticide Data Program, [23] a program started by the United States Department of Agriculture is the largest tester of pesticide residues on food sold in the United States.
