Description
The application divides an application.The applying date of original application is: 2012-01-16; The application number of original application is: 201210011486.X; The denomination of invention of original application is: the mesosulfuron complex weedicide.
Technical field
The present invention relates to a kind of weed killer herbicide, refer in particular to a kind of complex weedicide that contains mesosulfuron.
Background technology
Wheat is the most important cereal crops of northern China, concerning the grain security of national economy and country, mainly take winter wheat as main, account for 90%, and the weeds of wheatland has affected the growth of wheat.The wheat main weeds has 30 kinds of left and right, as amur foxtail, Alopecurus, bromegrass, annual bluegrass, hard grass, the caput grass, Chinese silvergrass, clearvers, the ox chickweed, Veronica, crack rice neat, pale persicaria, tongue of sparrow grass, common vetch, sarson, broadcast the ma wormwood artemisia, common vetch, corn gromwell, shepherd's purse, wartwort, field bindweed, field thistle, the rice crock, lamb's-quarters, little lamb's-quarters, plaque holds and benbie, wheat paddock foliar herbicide commonly used is only good to the broadleaved herb control efficiency at present, to the anti-heterodyne of grassy weed, part is to effective not all right again to the broadleaved herb effect of gramineous grass, simultaneously because some weed killer herbicide is used the pesticide resistance that causes weeds very large year after year.
Mesosulfuron is selective herbicide after sulfonylurea inner sucting conduction type seedling, is the inhibitor of acetolactate synthase, and grass cutting blade namely stops growing after absorbing medicament, withered gradually.The longevity of residure of this medicine in soil is short, does not affect the second stubble crop growth, is mainly used in wheat, and naked barley etc. are except grassy weed and some broad leaved weed.In grassy weed mesosulfuron to the preventive effect of Alopecurus, wild oat, annual bluegrass and Annual Ryegrass higher than the preventive effect to hard grass, bromegrass, Tong grass and Triticum tauschii, in broad leaved weed, mesosulfuron to shepherd's purse, broadcast ma wormwood artemisia and ox chickweed preventive effect higher, lower to conical silene herb, corn gromwell, clearvers and wartwort preventive effect.
