Sulfonylureas represent a major advance in global crop protection technology and have revolutionized weed control by introducing a unique mode of action. The future of the SU herbicides in the turf industry. The sulfonylureas have soil half-lives that range from a few days to two months, and they are degraded by soil microbes and chemical hydrolysis, depending on soil conditions (Sarmah and Sabadie, 2002). 0000104818 00000 n As a result, it is recommended to use a water rate of 200-500 L/ha.

Sulfonylurea Herbicides' Fate in Soil: Dissipation, Mobility, and Other 0000122926 00000 n Use: When treating annual ryegrass it often needs a second treatment after 4 to 6 weeks. 0000003113 00000 n [21], There is some evidence that sulfonylureas also sensitize -cells to glucose, that they limit glucose production in the liver, that they decrease lipolysis (breakdown and release of fatty acids by adipose tissue) and decrease clearance of insulin by the liver. As it moves downward through the soil, plant roots are able to take up any remaining herbicide. Sulfonylureas are divided into 3 classes on basis of therapeutic efficiency of their antidiabetic action: They include acetohexamide, carbutamide, chlorpropamide, glycyclamide (tolcyclamide), metahexamide, tolazamide and tolbutamide.
