Description
Technical field
The present invention relates to a kind of herbicidal composition of cinosulfuron-containing, be specifically related to a kind of weed killer herbicide that is used to prevent and treat rice field grassy weed, broad leaved weed and sedge weed, it is the active ternary herbicidal composition of forming by cinosulfuron, penoxsuam and cyhalofop-butyl.
Background technology
Along with numerous weed killer herbicide kinds continue to use in the paddy field large tracts of land, produce many problems, sum up as follows: 1. the weeds resistance is outstanding, wherein comparatively outstanding to the resistance of Stam F-34, dichloro quinolinic acid, butachlor, benthiocarb with the barnyard grass grass, recently, common weeds such as sedge family, Pontederiaceae, Alismataceae such as difformed galingale herb, firefly Lin, angustifolia arrowhead herb, Monochoria korsakowii, Monochoria vaginalis have produced resistance to sulfonylurea herbicide, make the weeding problem more become complicated.2. perennial weed harm becomes major issue, and particularly the sedge family perennial weed is more outstanding.3. the careless problem of preventing and kill off with moleplant seed of barnyard grass at advanced age need solve; 4. the grass spectrum of killing of weed killer herbicide kind remains to be enlarged, and prolongs the lasting phase that soil is prevented and kill off medicament.5. more urgent for the demand of wide spectrum, selectivity weed killer herbicide kind strong, easy to use.
Use weed killer herbicide behind the seedling that penoxsuam system is developed by U.S. Tao Nongke company (Dow AgroSciences), it causes effect by inhibition acetolactate synthestase (ALS).On September 24th, 2004 is in U.S. EPA official register registration, applies in southern US rice district in 2005, registers in China in 2008.This medicament can very effectively be prevented and kill off the barnyard grass grass and (comprise Stam F-34, the barnyard grass grass of dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), moleplant seed and annual sedge weed, simultaneously, it also can prevent and kill off anti-sulfonylurea weeds in the paddy field, and many broad-leaveds and sedge weed and barnyard grass grass etc. had residual activity, for present paddy field is composed the widest kind with killing grass in the weed killer herbicide, but use cost height, limiting its large tracts of land promotes the use of, therefore penoxsuam and other kind combinations of herbicides is composite, improve drug effect, enlarge the control of weeds spectrum, reduce usage amount, enlarging using of this medicament is present urgent problem.
