Abstract
The invention relates to a herbicide composition containing flufenacet and isoproturon and an application thereof. The mass ratio of flufenacet to isoproturon, the active ingredients of the pesticide composition, is (5-80) to (10-80). The pesticide composition has the advantages that the pesticide composition shows obvious synergistic effects in the ratio range, thus reducing the dosage of pesticides, the number of pesticide use, the pesticide use cost and the adverse impacts of the pesticides on the ecological environment; as the weed control spectrum is expanded, the problems of grassy weeds and part of broadleaf weeds in wheat fields are solved by using the pesticides once, thus making up for the defects and limitation during single agent use; the service life of the agent is prolonged, which is of important significance to comprehensive treatment of the resistance of the weeds; the pesticide composition takes effect quickly, has long duration, is low in use cost and can be used for controlling the grassy weeds and part of broadleaf weeds in the wheat fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide containing flufenacet and isoproturon preventing and kill off grass family and part broad leaved weed for wheat paddock.
Background technology
According to statistics world's cereal produce annual due to illness, worm, crop smothering loss 14%, the loss that wherein crop smothering causes is about 11%, and Weed infestation 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 accounting for agricultural chemicals sales volume increases year by year, uses area and expands year by year.Wheat is the crops that Consumption of China amount is maximum, cultivated area is maximum, gross yield is maximum, per unit area yield is the highest, has consequence in the world.But the serious of wheat crop smothering is the major obstacle restricting its high yield, stable yields.Current wheat weeds is prevented and kill off mainly based on cauline leaf spraying after weeds seedling, and weed killer herbicide kind is based on acetyl-CoA carboxylase inhibitor class.The continuous Long-Time Service of single herbicide causes herbicide resistance obvious, and the weeds such as wheatland Alopecurus, amur foxtail, Wang grass, ox chickweed, shepherd's purse all create obvious resistance to multiple weed killer herbicide.In addition, cornfield haulm process weed killer herbicide is slightly poor to Safe to wheat, and medicine processus aboralis is met low temperature and is easy to produce poisoning, threatens Wheat Production.Use after exploring wheat weeds seedling, effectively prevent and kill off resistance, efficient, the safety herbicide of malignant weed seem particularly important.
Flufenacet, chemical name: 4 '-fluoro-N-isopropyl-N-2-(5-Trifluoromethyl-1,3,4-thiadiazoles-2-base oxygen base) antifebrin.Belong to fragrant oxanamide class weed killer herbicide, absorb by plant roots and cauline leaf, effective division of T suppression cell and growth.Flufenacet effectively can be applied to corn, wheat, barley, Soybean and Other Crops Tanaka prevent and kill off numerous annual gramineous weeds and some broad leaved weed.
Isoproturon, chemical name: 3-(4-isopropyl phenyl)-1,1-dimethyl urea or-3-are to cumenyl-1,1-dimethyl urea.Belong to phenyl ureagroup herbicides, absorb inhibited photosynthesis electron transmission mainly through root and cauline leaf, for before selectivity seedling, herbicide after seedling, also there is selection systemic action.Isoproturon is efficient, broad-spectrum herbicide, can be applicable to the crop Tanakas such as wheat, corn, paddy rice and prevents and kill off grass family and broad leaved weeds.
Patent flucarbazone isoproturon (application number: 201210011487.4) be background information is had according to isoproturon, flucarbazone isoproturon to wheatland grass family and part broad leaved weed cauline leaf treatment effect outstanding, but sealing effect is poor, flufenacet isoproturon has outstanding cauline leaf process and sealing effect to wheatland grass family and part broad leaved weed, a drug solves Weed infestation in wheat whole breeding time, has saving of labor, labour-saving advantage.
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 being difficult to effectively to control Weed infestation in wheat whole breeding time, the object of this invention is to provide a kind of composition pesticide containing flufenacet and isoproturon, 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 above-mentioned application containing the composition pesticide of flufenacet and isoproturon.

The optimum proportioning screening of embodiment 6 flufenacet and isoproturon
1) flufenacet and the screening of isoproturon optimum proportioning
In order to understand flufenacet and isoproturon mixture further to the synergy of weeds, the present inventor has carried out formulation screening test to flufenacet and isoproturon mixture.
Shi Wang grass (Beckmanniasyzigachne (Steud.) Fern.), ox chickweed (Malachiumaquaticum (L.) Fries), in October, 2013 picks up from experimental field, Jiangsu Province Agriculture Science Institute, adopt natural air drying under rear room temperature condition, load paper bag, 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 flufenacet and the former medicine of isoproturon that first take certain mass, add the Tween 80 aqueous solution dilution that methyl alcohol fully dissolves rear use 0.1%, be mixed with single dose mother liquor, arrange serial proportioning according to mixture object, it is stand-by that each proportioning arranges 5-7 concentration gradient.Polypots (15cm × 11cm × 7cm) is filled air-dry fine earth, in infiltrating irrigation mode bottom polypots, makes soil completely moistening.Soil be horse liver soil, pH6.7, the content of organic matter 1.6%, air-dry sieve after for subsequent use.Each polypots Bo Wang grass, ox chickweed, broadcast rear fine earth and cover, thickness is about 0.2cm.When weeds 2 ~ 3 leaf phase, weeds are fixed to 15 strains/alms bowl, put into Jiangsu Province Agriculture Science Institute 300m after spraying process
2greenhouse by solar heat is cultivated.
Ding after medicine phase Guan Cha Wang grass, ox chickweed growing state.After medicine, 30 days investigation weeds overground part fresh weights, calculate fresh weight inhibition namely to the preventive effect of target weeds.Adopt DPS data handling system to obtain the virulence regression equation of each process, calculate ED
50value and 95% confidence limit.Co-toxicity coefficient is calculated by the abundant method of Sun Yun.Co-toxicity coefficient is greater than 120 and is expressed as synergistic effect, is less than 80 and is expressed as antagonism, be expressed as summation action between 80 ~ 120.
Result of the test: medicine post processing is observed for 20 days, flufenacet and isoproturon mixture use Hou Wang grass, ox chickweed partial blade jaundice inhibitory action that is careless to withered Dui Wang, ox chickweed rises ， Dui Wang grass with the increase of drug concentration, ox chickweed has very high biologically active.
