Abstract
The invention relates to a weeding composition containing benzobicylon and halosulfuron-methyl. The weeding composition comprises active ingredients, namely benzobicylon and halosulfuron-methyl, wherein a weight part ratio of the benzobicylon to halosulfuron-methyl is (15:1)-(1:60). The weeding composition has an obvious synergistic effect on barnyard grass and dayflower, a weeding effect is improved, the herbicide controlling spectrum is widened, and the weeding composition is applied to controlling barnyard grass in paddy fields, annual broadleaf weeds and cyperaceae weeds.
Description
Technical field
The invention belongs to agriculture weeding technical field, be specifically related to a kind of Herbicidal composition for rice field that halosulfuronmethyl, benzobicylon be active ingredient of take, said composition has synergistic function, is applicable to prevent and kill off paddy field barnyard grass, annual broadleaf weed and sedge weed.
Background technology
Along with progressively eliminating of high-toxic pesticide, need efficient, low toxicity, safety, environment amenable pharmaceutical preparations, the long-term use of agricultural chemicals simultaneously produces the pesticide resistance of disease pest and weed, requirement to control medicament is also more and more higher, this just needs agricultural chemicals research staff to develop the pharmaceutical preparations of highly effective and safe, meets control requirement.Because China's agricultural chemicals initiative is at the early-stage, the pesticide species with independent intellectual property right can't be satisfied the demand, so the pesticide mixed preparation of development of new, is the only way of current Agrochemicals.
Halosulfuronmethyl (halosulfuron-methrl) is sulfonylurea wide spectrum selectivity inner-adsorption conduction-type herbicide, mainly by root system, be absorbed, also can absorb by cauline leaf, in weeds plant body, shift rapidly, suppress growth, weeds are dead gradually, can prevent and kill off annual broadleaf weed and sedge weed, are applicable to the crops such as corn, paddy rice.
Benzobicylon (benzobicyclon) is the novel double-octane class albinism paddy field post-emergence herbicide of Japanese SDS exploitation, to rice safety, high with Environmental compatibility, can effectively prevent and kill off the paddy field weeds such as barnyard grass, Monochoria vaginalis, firefly Lin, false rice, pondweed, annual broadleaf weed.
Weed killer herbicide is rationally composite is to improve preventive effect, expand herbicide spectrum or widen service time, delaying the speed of shift of weed community, reducing the resistance risk that the single use of agricultural chemicals brings, alleviate the pollution to environment, reduce a kind of effective ways of use cost and reduction herbicide residue.The inventor conducts in-depth research being mixed of halosulfuronmethyl, benzobicylon, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that halosulfuronmethyl, benzobicylon are mixed, within the scope of certain mixed ratio, barnyard grass, dayflower are shown to synergistic function, after further study, completed the present invention.
