Abstract
The invention belongs to the technical field of farm chemical herbicides, and particularly relates to a herbicide composition containing halauxifen-methyl and halosulfuron-methyl. The herbicide composition is suitable for wheat fields. The weight ratio of the active ingredient halauxifen-methyl to the active ingredient halosulfuron-methyl ranges from 1:1.25 to 1:80. According to the herbicide composition, the weed control spectrum is broadened, the control effect is enhanced, the situation that the herbicide resistance of weeds can be rapidly generated when weed control is performed with a single herbicide is avoided, generation of the herbicide resistance of weeds is retarded, the dosage is reduced, the use cost is lowered, and environmental pollution is relieved.
Description
Technical field
The invention belongs to pesticide herbicide technical field, the one that is specifically related to be applicable to wheatland contain fluorine chloropyridine ester andThe herbicidal composition of halosulfuronmethyl.
Background technology
Wheat is one of China's staple food crop, and its cultivated area and total output are only second to paddy rice, national cultivated areaReach more than 3,000 ten thousand hectares, approximately 4.5 hundred million mu, account for the 22%-30% of national cultivated area, be about the 20%-of cereal crops sown area27%, approximately 100,000,000 tons of wheat total outputs, reach the 22%(Wu Ming honor of total output of grain etc., and 2013, agricultural chemicals). Wheat is that China is mainCommodity food and strategic reserves grain kind, in grain-production, circulation and consumption, there is critical role, development Wheat Production to meState's national economic development and people's lives are significant. According to national weeds reconnaissance information, China's wheat weeds kindHave kind more than 200, crop smothering area accounts for the more than 30% of wheat planting area, and loss accounts for 15% of wheat total output. Therefore wheatlandControl of weeds is one of important process of wheat planting.
Herbicide is the conventional measure of current wheat weeds control, to promoting wheat yield to improve and saving planting cost toolThere is important effect. But long-term, the large scale application of herbicide, there is Weed Resistance, kind in farmland weed chemical controlGroup's succession and drug injury problem are on the rise, and have a strong impact on the high yield of wheat and safety (Wei Youhai, the Hubei of good harvest and succession cropAgricultural sciences, 2011.4). At present, in wheatland there are some drawbacks in conventional medicament. As phonetic in sulfonylurea herbicide tribenuron-methyl, benzylThe grand consumption of sulphur is too high, and late use meeting causes poisoning to succession crop peanut, soybean with mistake. Phenoxy carboxylic acid herbicides 2,4-drips fourthEster, mcpa sodium consumption are too high and use and improperly easily cause chemical injury of crops to produce drift can to produce near dicotyledonous cropsCrude drug evil.
Long-term use single herbicide to prevent and kill off can to cause susceptible weeds quantity to decline, insensitive or malignant weed quantitativelyRise, cause that weed community changes. In the winter wheat producing region of the single use of herbicide, wheat weeds group has occurred seriousChange, the malignant weed that the multiple herbicides such as clearvers, wartwort, grandmother's sodium, shepherd's purse are all difficult to control increases year by year, and serious shadowThe results of wheat crop output are rung.
Fluorine chloropyridine ester, English common name halauxifen-methyl. The Dow Agrosciences, LLC. was April 10 in 2014Day is obtained the former medicine of 93% fluorine chloropyridine ester and registers temporarily, and registration card number is LS20140138, the micro-poison of toxicity. Fluorine chloropyridine ester(Halauxifen-methyl) be a kind of pyridine carboxylic acid class herbicide. Fluorine chloropyridine ester is virtue in synthetic auxin class herbicideFirst product in the new chemical type of yl pyridines acid. It has simulated the effect of high dose plant growth regulator, causes specificThe overstimulation of auxin regulatory gene, disturb multiple growth courses of sensitive plant. Fluorine chloropyridine ester is for broad-leaved after budWeeds control. The herbicide that contains fluorine chloropyridine ester can be by preventing and kill off partial resistance weeds, for example clearvers, chickweed and cannabisWeeds carry out resistance management. In addition, fluorine chloropyridine ester can be by microorganism fast degradation in environment, for succeeding crop plantation is carriedFor larger flexibility. Amaranthus retroflexus, piemarker, yellow clever nutgrass flatsedge are had to good preventive effect.
Halosulfuronmethyl, Chinese synonym is: 3-(4,6-dimethoxypyridin-2-yl)-1-(the chloro-4-first of 1-methyl-3-Oxygen base formoxyl pyrazoles-5-yl) sulfonylureas; Pyrrole chlorsulfuron; The chloro-5-of 3-(4,6-dimethoxypyridin-2-base amino carbonyl aminoSulfonyl)-1-methylpyrazole-4-carboxylate methyl ester; Chlorine pyrrole chlorine sulphur is grand; The chloro-5-[[[[(4 of 3-, 6-dimethoxy-2-pyrimidine radicals) ammoniaBase] carbonyl] amino] sulfonyl]-1-methyl isophthalic acid H-pyrazoles-4-methyl formate; Chloropyridine sulphur is grand; Halosulfuronmethyl (standard items).English name Halosulfuronmethyl. English synonym is: SEMPRA (R); NC-319; Mon12000; PERMIT;PERMIT (R); Battalion; BATTALION (R); HALOSULFURON-METHYL. CAS 100784-20-1. Chlorine pyrrole is phoneticSulphur is grand, be mainly used in wheat, corn, paddy rice, sugarcane, lawn etc. and prevent and kill off broad leaved weed and nutgrass flatsedge, as storehouse ear, Datura, artemisiifolia,Amaranthus retroflexus, flowerofanhour root or herb, knotweed, purslane, black nightshade, Cassia tora, lead a cow, the rhizome of nutgrass flatsedge etc. This medicament can suppress side chain ammonia in plantThe biosynthesis of base acid leucine, isoleucine, valine, but improper use may be to doing deposits yields poisoning, and Different CropOr between crop different cultivars of the same race, the drug resistance of sulfonylurea herbicide be there are differences.
Along with the development of Development of China's Urbanization, rural laborer transfers to cities and towns in a large number, and concentration of landholdings degree improves, wheatlandControl of weeds is more and more stronger to the dependence of herbicide. Efficiently, low toxicity, low-residual, succession crop harm is little is current herbicideThe important directions of research and development.
The deficiency existing in actual application in order to make up above each single dose, inventor furthers investigate, greatlyUnexpected discovery on the formula indoor screening of amount and the basis of field control effectiveness test, herbicidal composition of the present invention is in certain proportioningComposite in scope, weeds of wheat is had to good prevention effect, the preventive effect showing and activity level exceed each componentStack, there is unforeseeable synergistic function, solved above two herbicides and deposited in herbicide spectrum, preventive effect and securityLimitation, reached and expanded herbicide spectrum, improve preventive effect, improve the object of security, can meet current agricultural to weedingThe demand of agent.
Summary of the invention
The object of the invention is to the defect for current wheat paddock herbicide, a kind of broad weed-killing spectrum, herbicidal effect are providedGet well, use safety, be conducive to the herbicidal composition of the weeds of wheat comprehensive regulation.
The present invention has adopted following technical scheme:
