(57) Abstract:Potassium salt of 2-chloro-N-[(4-methoxy-6-methyl-1,3,5-triazine-2-yl)aminocarbonyl] benzosulfimide is used as a herbicide on flax, both individually and jointly with other herbicides, for example Targ-super and 2M-4. The specified salt use in controlling undesirable vegetation in crops of flax in the amount of not more than 5 g/ha 2 c. and 2 C.p. f-crystals, 9 PL. The invention relates to chemical means of weed control in crops based on derivatives sulfonilmocevina, in particular salts of 2-chloro-N-/(4-methoxy-6-methyl-1,3,5-triazine-2-yl) aminocarbonyl/benzosulfimide(chlorsulfuron) and specifically to its potassium salt of formula I:
< / BR>The invention relates also to a method of controlling undesirable vegetation in crops of flax by processing plants weed-killing drug on the basis of salts of formula I, as well as its mixture with other herbicide-active compounds, for example with dimethylamine salt of 2-methyl-4-chlorophenoxyacetic acid.It is known the use of the herbicide N-substituted nitrogen-containing heterocyclic derivative sulfonylureas total FD is from, W is oxygen, and its sodium, potassium, calcium, 2-chloroethylamine salt in the amount of 0.005-2.0 kg/ha (patent USSR N 1435141).Of salts chlorsulfuron, which is also described in this patent is characterized by sodium and calcium salts are used at a dose of 0.005 kg/ha according to the current matter.Herbicide action described compounds, including salts, apply to weeds in crops of cereals, in particular wheat.Known herbicide compositions based on salts of sulfonylureas of the General formula III:
< / BR>where M is ammonium, substituted ammonium, alkali metal (sodium) ions and carbocyclic and inorganic acids (U.S. patent N 4936900).Potassium salt of chlorsulfuron none of the known sources of information are not described not described.Known drug use clay in the form of a 75% dry fluid suspension (active substance - chlorsulfuron-2-chloro-N-(4-methoxy-6-methyl-1,3,5-triazine-2-yl)-aminocarbonyl /benzosulfimide) as a herbicide on flax at a dose of 13 to 20 g/ha (List of chemical and biological means of pest control, plant diseases and weeds, plant growth regulators and Fermo is, Plant protection, No. 3, 1993 ) or at a dose of 10 - 15 g/ha of nutrient content (N.N. Melnikov and others, Handbook, Pesticides and plant growth regulators.
