Introduction:
Gyatis is a sulfonylurea herbicide that controls a wide range of grasses and broadleaf weeds in wheat. It is a combination herbicide based on Mesosulfuron-methyl and Iodosulfuron-methyl sodium. It is a novel safened sulfonylurea-based product for post-emergent application. In agreement with other herbicides of the sulfonylurea group, the primary target site of action is the enzyme acetohydroxyacid synthase (AHAS). Both active ingredients are phloem-xylem mobile in the target weed, both via the foliage and via the soil, with a clear predominance of foliar action. The visible symptoms of herbicide action are shown within the first few days after application, including the appearance of chlorotic patches, followed by slow shoot necrosis. Susceptible plants stop growth almost immediately after post-emergence application. Plants will be completely killed 4 to 6 weeks after application.
