Technical field
The present invention relates to a kind of Herbicidal combinations; it comprises (1) 2-(4; 6-dimethoxypyridin-2-base carbamoyl sulfamoyl)-N; nicosulfuron Nicosulfuron) or its salt, (2) 2-chloro-4-ethylamino-6-isopropylamino-1 N-dimethyl nicotinamide (common name:; 3, atrazine Atrazine), (3) surfactant, (4) stabilizing agent and (5) carrier 5-triazine (common name:.In addition, the invention still further relates to a kind of method by this Herbicidal combinations control undesired plants of use or its growth.
Background technology
JP-A-8-34703 discloses a kind of Herbicidal combinations, its comprise comprise nicosulfuron or its salt and atrazine pyridinsulfonamide compounds as active component.In the disclosure text, the expansion and the persistence herbicidal effect of the herbicidal spectrum of this Herbicidal combinations disclosed.Yet, do not have open or suggestion to be implemented in the time stability (bin stability) of nicosulfuron in the Herbicidal combinations that comprises nicosulfuron, atrazine, surfactant and carrier by some specific stabilizing agent in the prior art.
The problem to be solved in the present invention
The inventor has carried out big quantity research, and find a kind of Herbicidal combinations that comprises nicosulfuron or its salt, atrazine, surfactant and carrier, thereby the time stability (bin stability) of a small amount of nicosulfuron that promptly can the appreciable impact activity of weeding is excellent especially, has therefore finished the present invention.
