Abstract
The invention discloses a pesticide composition comprising ethoxysulfuron and halosulfuron-methyl and application thereof, the pesticide composition comprises the active components of the ethoxysulfuron and the halosulfuron-methyl, and the mass ratio of ethoxysulfuron to halosulfuron-methyl is 0.05-10: 0.5-10. The pesticide composition, showing obvious synergistic effect on the matching range, reduces the pesticide dosage, reduces the pesticide dosing number, reduces the pesticide dosing cost, reduces the adverse effects of pesticides on ecological environment, expands the herbicidal spectrum, can solve various weed problems by one-time use, makes up the defects and limitations when using a single agent, extends the agent service life, has the vital significance to the comprehensive treatment of weed resistance, is fast in drug efficacy, long in period of preserving effect and low in use cost, and can be used to control broadleaf weeds and sedge weeds in rice fields.
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 ethoxysulfuron and halosulfuronmethyl of paddy field broad leaved weed and sedge 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.Paddy rice 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 in the world consequence.But the serious of rice field crop smothering is the major obstacle of its high yield of restriction, stable yields.At present, the pattern of preventing and kill off adopt " envelope, two is killed, three benefits " of weeds in paddy field is carried out more, at present for different phase, there is different weed killer herbicide kinds available, but most kinds are difficult to guarantee a drug and keep paddy rice interior without grass whole breeding time, the increase of medication number of times has greatly increased cost accounting undoubtedly, has also increased the weight of the impact on environmental ecology.Therefore, exploratory development paddy field is once used and keeps paddy rice without careless safety, highy potent herbicide, to seem particularly important in whole breeding time.
Ethoxysulfuron, chemical name: 1-(4,6-dimethoxypyridin-2-yl)-3-(2-phenoxy ethoxy sulfonyl) urea.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, then withered.Ethoxysulfuron can effectively be prevented and kill off broad leaved weed and the sedge weed of sugarcane, wheat, paddy field.
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 control paddy rice weeds (especially pernicious broad leaved weed of rice field middle and later periods) harm in whole breeding time, the object of this invention is to provide a kind of composition pesticide containing ethoxysulfuron and halosulfuronmethyl, make it have efficient, wide spectrum, environmentally friendly, be beneficial to the features such as the weeds in paddy field comprehensive regulation.Another object of the present invention is to provide a kind of application of the above-mentioned composition pesticide containing ethoxysulfuron and halosulfuronmethyl.
