Abstract
The invention discloses a herbicide composition which contains oxadiazon and penoxsulam. The herbicide composition comprises the following effective components: oxadiazon, penoxsulam and the balance of pesticide adjuvants, wherein the ratio of the oxadiazon and the penoxsulam in parts by mass is 1:1-140:1, and the total weight of the oxadiazon and the penoxsulam accounts for 5%-80% of the herbicide composition in percentage by weight. The herbicide composition disclosed by the invention is used for preventing and controlling the annual weeds of a paddy field; compared with the independent use of a single agent, the herbicide composition disclosed by the invention obviously enhances the weeding effect, enlarges the weed control spectrum, achieves safety in crops, reduces the usage amount of pesticides, reduces the pollution of the pesticides to the environment and postpones the generation of the drug resistance of the weeds.

Variety classes weed killer herbicide mixture, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.Screening by formulation of pesticide, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay disease, worm, the drug-fast generation of crop smothering, is the important means that agricultural synthesis is administered.The formula screening of inventor Dui Evil humulone and penoxsuam conducts in-depth research Fa Xian Evil humulone and penoxsuam carries out mixture, in certain mixed ratio scope, paddy field annual weed is had to synergy or summation action, after further study, completed the present invention.
The composite relevant report of Wei Fa Xian Evil humulone and penoxsuam at present.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention be by this Herbicidal combinations for preventing and kill off farmland weed, be particularly useful for paddy field annual weed.
Technical scheme: for achieving the above object, the invention provides the Herbicidal combinations of a kind of Han oxadiazon and penoxsuam, it comprises active ingredient Evil humulone and penoxsuam; the ratio of quality and the number of copies of Evil humulone and penoxsuam is 1:1～140:1; Evil humulone and the penoxsuam gross mass mark percentage composition in Herbicidal combinations is 5%～80%, and all the other are in agricultural chemicals, to allow to use and acceptable auxiliary element.
Herbicidal combinations those skilled in the art of the present invention can be according to known method, selects suitable pesticidal preparations auxiliary element, makes the upper conventional formulation of the agriculturals such as suspending agent, oil-suspending agent, water dispersible granules, wetting powder, effervescent tablet, granulae effervescentes.
The auxiliary agent using in Herbicidal combinations provided by the invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, safener, thickener, pH adjusting agent, defoamer, antifreezing agent, deionized water, filler etc., all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption, according to formula requirement, are determined through simple test.
The production technology of the various application forms of Herbicidal combinations provided by the invention all belongs to existing known technology, does not repeat them here.
The frequency of administration of Herbicidal combinations provided by the invention and amount of application have small variations with crops, weeds, weather condition variation, can be by using suitable dosage to reach the object of effective control.
The present invention has expanded herbicide spectrum, and composition has Synergistic response to target, can provide good solution for uncultivated area, orchard, Cotton Fields, preventing and kill off of vine crop field weed, and the weeds comprehensive regulation is had to positive effect.
