Report of the Food Quality Protection Act (FQPA) Tolerance Reassessment Progress and Risk Management Decision (TRED) for Primisulfuron-methyl. Crop-selective sulfonylurea herbicides have been commercialized for use in wheat, barley, rice, corn, soybeans and oilseed rape, with additional crop-selective compounds in cotton, potatoes, and sugarbeet having been noted. The herbicides inhibit acetohydroxy acid synthase (AHAS), a key enzyme in the biosynthesis pathway of branched-chain amino acids valine, leucine, and isoleucine in bacteria, fungi, and plants (3, 4, 8, 13).The use of sulfonylurea herbicides has developed . In addition, Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data.

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. These herbicides can either be pre-emergent or post-emergent herbicides and are systemic or work on the leaf surface. Other points of note: Dont mix with a surfactant or crop oil as it causes yellowing in tolerant turf; Nominee claims to be slow acting. They work on a broad range of grasses and broadleaf weeds, but not on crops they are designed to protect. Select one or more newsletters to continue.
