They work on a broad range of grasses and broadleaf weeds, but not on crops they are designed to protect. Always read the label; Due to an increase in the chance of turf damage avoid using these within seven days of organophosphate insecticides; Their high specificity means that turfgrass tolerance varies. McCullough and Hart (2010) found the most successful rate for. In a 1998 survey, nicosulfuron was detected in 67% of 130 Midwestern streams and rivers (Battaglin et al., 2000). At soil pH of 7.0 and greater, some of these sulfonylurea herbicides tend to persist for longer periods with half-lives extending into years rather than days. Sulfonylurea herbicides were not mutagenic in vitro and most were not carcinogenic in animals. 554 53 0000140355 00000 n These herbicides are taken up by the roots and foliage and act by disrupting protein synthesis. Potential routes of human exposure include consumption of foods grown in soil to which the sulfonylureas were applied or drinking contaminated water.Tolerances or acceptable concentrations have been established for various edible food crops to which several of these herbicides may be applied (U.S. EPA, 2002, 2004a, and 2004b).

Federal Register Environmental Documents. Dihydromyricetin The persistence and activity of these sulfonylureas are affected by soil pH. They function by interfering with biosynthesis of the amino acids valine, isoleucine, and leucine, specifically via acetolactate synthase inhibition. Most SUHs are resistant to hydrolysis and oxidation under environmental conditions but are only moderately persistent because they are degraded by soil microorganisms. [citation needed], Sulfonylureas can be used to treat some types of neonatal diabetes. Sulfonylureas inhibit the plant enzyme, acetolactate synthase, resulting in impaired branch chain amino acid synthesis, and are generally more potent herbicides than the phenylureas.
