Abstract
The invention discloses an herbicide composition containing chlortoluron, pretilachlor and diflufenican and a use thereof. Active components of the herbicide composition comprise chlortoluron, pretilachlor and diflufenican. A mass ratio of chlortoluron, pretilachlor to diflufenican is 10-150: 10-50: 1-50. The herbicide composition has obvious synergism in the above ratio range, reduces an herbicide use dosage, reduces herbicide use frequency, reduces an herbicide use cost, reduces the unfavorable influence produced by the herbicide on an ecological environment and enlarges a weeding spectrum. Through one herbicide use step, various weed problems are solved and defects and limitation of single-ingredient herbicide use are overcome. The herbicide composition prolongs a service life and has an important meaning for comprehensive control of weed resistance. The herbicide composition can fast produce effects, has long action time, has a low use cost and can be used for preventing and controlling gramineous weeds and broadleaf weeds in a wheat field.
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 diflufenican 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.Wheat in China cultivated area and output rank first in the world, and are Wheat Production state and countries of consumption the biggest in the world.But weeds harm is one of limiting factor of wheat paddock high yield and high quality always.Whole nation wheatland crop smothering area reaches more than 30%, loses every year nearly 5,000,000,000 kilograms of wheat, severe inhibition the production of China's wheat.Weeds of wheat pesticide resistance problem is more and more serious at present, the narrow easy generation poisoning of Common Herbicides herbicide spectrum.Therefore, exploratory development wheat paddock once uses and keeps seeming particularly important without careless safety, highy potent herbicide in wheat whole breeding time.
Chlortoluron, chemical name: 3-(the chloro-4-tolyl of 3-)-N, N-dimethyl urea or N-(the chloro-4-aminomethyl phenyl of 3-)-N, N-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 the Dry crop Tanakas such as wheat, barley, corn, Chinese sorghum, cotton and prevents and kill off grass family and broad leaved weeds.
The third careless amine, chemical name: 2-is chloro-2 ', 6 '-diethyl-N-(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.
Diflufenican, the chloro-2-of chemical name: 2,4-bis-(α, α, α-trichlorine fluorine m-phenoxy)-3-pyridine anilide.Belong to acetamide-group herbicides, can absorb by weeds young root or young shoot, in plant body, conduct, suppress carotenoid biosynthesis, cause chlorophyll destroyed, membranolysis, weeds show as young shoot decolouring or white, and last whole strain is wilted dead.Diflufenican can effectively be prevented and kill off grassy weed and the broad leaved weed of wheat paddock.
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 diflufenican, 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 diflufenican.
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 diflufenican
In order further to understand chlortoluron, the third careless amine and the synergy of diflufenican mixture to weeds, the inventor has carried out formulation screening test to chlortoluron, the third careless amine and diflufenican mixture.
Test material: amur foxtail (Alopecurus aequalis Sobol.), Veronica (Veronica didyma Tenore), pick up from experimental field, Jiangsu Province Agriculture Science Institute in May, 2013, 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 diflufenican 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 30 of amur foxtails, 30 of Veronicas, 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 amur foxtail and Veronica after medicine.Within after medicine 30 days, investigate amur foxtail and Veronica 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, diflufenican 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.
