Abstract
The invention discloses pesticide composition containing chlortoluron, pretilachlor and halosulfuron-methyl and an application of the pesticide composition. The pesticide composition comprises effective components, namely, the chlortoluron, the pretilachlor and the halosulfuron-methyl, wherein the mass ratio of the chlortoluron to the pretilachlor to the halosulfuron-methyl is in a range of (15-120):(10-50):(0.5-10). The pesticide composition has an obvious synergistic effect within the matching range, the dosage of a pesticide is reduced, pesticide usage times are reduced, the pesticide usage cost is reduced, and adverse effects caused by thepesticide on theecological environment are reduced; theherbicide controlling spectrum is expanded, various weed problems are solved through one-time application, and defects and limitations during single agent usage are overcome; the service life of the pesticide composition is prolonged, and thepesticide composition is significant tocomprehensive treatment of weed resistance. The pesticide effect is played quickly, and the pesticide composition is long in lasting period, low in usage cost and capable of being used for controllingwheat or barley field grass weeds and broadleaf weeds in the period before seedling and after sowing of wheat or barley as well as in the three-leaf period after sowing of the wheat or the barley.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of for preventing and kill off the composition pesticide containing chlortoluron, the third careless amine and halosulfuronmethyl of wheat (barley) field grassy weed, broad leaved weed.
Background technology
According to statistics world's cereal produce every year due to illness, worm, crop smothering loss 14%, the loss that wherein crop smothering causes is about 11%, weeds harm is the key factor of restriction crop yield.The use of chemical herbicide is one of important symbol of agricultural modernization.In recent years, the sales volume of weed killer herbicide increases year by year, and the proportion that accounts for agricultural chemicals sales volume increases year by year, uses area and expands year by year.The crops that wheat is Consumption of China amount maximum, cultivated area maximum, gross yield maximum, per unit area yield is the highest, have consequence in the world.But the serious of wheat crop smothering is the major obstacle of its high yield of restriction, stable yields.Wheat weeds is prevented and kill off mainly and is sprayed as main taking cauline leaf after weeds seedling at present, and weed killer herbicide kind is taking acetyl-CoA carboxylase inhibitor class as main.Single herbicide continuously long-term use causes herbicide resistance obvious, and the weeds such as wheatland Alopecurus, amur foxtail, Wang grass, ox chickweed, shepherd's purse have all produced obvious resistance to multiple weed killer herbicide.Efficient, the safe weed killer herbicide that explore early application after Wheat Growing Soils sealing or wheat weeds seedling, can effectively prevent and kill off resistance, malignant weed seems particularly important.
Chlortoluron, chemical name: 3 (3-chlorine p-methylphenyls)-1,1-dimethyl urea.Belong to phenyl ureagroup herbicides, mainly absorb the transmission of inhibited photosynthesis electronics by root and cauline leaf, for before selectivity seedling, herbicide after seedling, also there is selection systemic action.Chlortoluron is efficient, broad-spectrum herbicide, can be applicable to wheat, corn, Soybean and Other Crops Tanaka and prevents and kill off grass family and broad leaved weeds.
The third careless amine, chloro-2 ', the 6 '-diethyl-N-of chemical name: 2-(2-propoxyl group ethyl) antifebrin.Belong to chloroacetanilide herbicides, can pass through plant hypocotyl, mesocotyl and coleoptile and absorb, root slightly absorbs, and suppresses effective division of cell, the formation of the synthetic and polysaccharide of impede protein matter simultaneously, also remote-effects photosynthesis and respiration.The third careless amine can effectively be applied to paddy field and prevent and kill off the grassy weeds such as barnyard grass, lady's-grass, moleplant seed, double part annual broadleaf weed and the sedge weed controlled.
Halosulfuronmethyl, the chloro-5-of chemical name: 3-(4,6-dimethoxypyridin-2-base amino carbonyl amino sulfonyl)-1-methylpyrazole-4-carboxylate methyl ester.Belong to sulfonylurea herbicide, can absorb by weeds root and leaf, in plant body, conduct, suppress acetolactate synthase activity, thereby cause weeds to stop growing, death.Halosulfuronmethyl can effectively be prevented and kill off broad leaved weed and the sedge weed of sugarcane, corn, paddy field.
Summary of the invention
Goal of the invention: in prior art to farmland weed develop immunity to drugs problem, single use control efficiency poor, once use the problem that is difficult to effectively to control weeds harm in wheat whole breeding time, the object of this invention is to provide a kind of composition pesticide containing chlortoluron, the third careless amine and halosulfuronmethyl, make it have efficient, wide spectrum, environmentally friendly, be beneficial to the features such as the wheat weeds comprehensive regulation.Another object of the present invention is to provide a kind of application of the above-mentioned composition pesticide containing chlortoluron, the third careless amine and halosulfuronmethyl.
Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is:

The best proportioning screening of embodiment 9 chlortolurons, the third careless amine and halosulfuronmethyl
In order further to understand chlortoluron, the third careless amine and the synergy of halosulfuronmethyl mixture to weeds, the inventor has carried out formulation screening test to chlortoluron, the third careless amine and halosulfuronmethyl mixture.
Test material: Lin's grass (Beckmannia syzigachne (Steud.) Fern.), ox chickweed (Malachiumaquaticum (L.) Fries (Stellaria aquatica (L.) Scop.), pick up from experimental field, Jiangsu Province Agriculture Science Institute in October, 2012, adopt natural air drying under rear room temperature condition, pack paper bag into, be placed in 4 DEG C ± 0.5 Refrigerator store.
Test apparatus: PWT-510 type spray tower, plum Teller AB135-S electronic balance, volumetric flask, triangular flask, beaker, graduated cylinder, polypots, pipette, chi, scissors etc.
Test method: the chlortoluron, the third careless amine and the former medicine of halosulfuronmethyl that first take certain mass, add methyl alcohol fully to dissolve the Tween 80 aqueous solution dilution of rear use 0.1%, be mixed with single dose mother liquor, according to mixture object, serial proportioning be set, it is stand-by that each proportioning arranges 5-7 concentration gradient.Polypots (15cm × 11cm × 7cm) is filled to air-dry fine earth, in polypots bottom infiltrating irrigation mode, make soil completely moistening.Soil is horse liver soil, pH6.7, and the content of organic matter 1.6%, for subsequent use after air-dry sieving.Each polypots is broadcast respectively 35 of Lin's grass, 15 of ox chickweeds, broadcasts rear fine earth and covers, the about 0.2cm of thickness.Broadcast after rear soil spraying is processed and put into Jiangsu Province Agriculture Science Institute 300m
2greenhouse by solar heat is cultivated, and maintenance ground moistening keeps the skin wet every day.
The growing state of seedling after the emerging and emerge of routine observation Lin grass, ox chickweed after medicine.Within after medicine 30 days, investigate Lin's grass, ox chickweed overground part fresh weight, calculate the i.e. preventive effect to target weeds of fresh weight inhibiting rate.Adopt DPS data handling system to obtain the virulence regression equation of single dose chlortoluron, the third careless amine, halosulfuronmethyl and 16 Ternary agent, calculate ED
50value and 95% confidence limit.With the abundant method calculating of Sun Yun co-toxicity coefficient.Co-toxicity coefficient is greater than 120 and is expressed as synergistic effect, is less than 80 and is expressed as antagonism, is expressed as summation action between 80～120.
Result of the test: medicine post processing is observed for 20 days, chlortoluron, the third careless amine and halosulfuronmethyl are in 15-120: 10-50: 0.5-10 ratio mixture is used rear Lin's grass, the jaundice of ox chickweed partial blade to withered, inhibitory action to Lin's grass, ox chickweed rises with the increase of drug concentration, and Tong grass, ox chickweed are had to very high biologically active.
