Production of trifluralin has declined since restrictions on product formulation were implemented in 1982 due to carcinogenicity and mutagenicity concerns. It is used on soybean crops, cotton, wheat, alfalfa, sunflowers, as well as certain other crops. How Much Trifluralin Was Generated? Exhibit 4.183.
