Abstract
The invention discloses a herbicide for a corn field. The effective components of the herbicide are composed of a component A, a component B and a component C in a mass ratio of 2-5: 5-10: 10-20, wherein the component A is thifensulfuron methyl, the component B is mesotrione or sulcotrione, and the component C is atrazine or pendimetalin. A wettable powder of the herbicide comprises, by mass, 25 to 35% of the effective components, 5 to 10% of a wetting agent and 10 to 15% of a dispersant, with the balance being a filling material. The herbicide for the corn field has partial synergistic effect on broad-leaf weeds and additive effect on gramineous weeds, is safe to corn, poses no influence on growth of corn, has improved prevention efficiency and broadened weed control spectrum, enables the usage amount of the effective components to be lowered, decreases cost for usage of the herbicide and reduces environmental pollution.
Description
Technical field
The invention belongs to technical field of pesticide, specifically a kind of corn field herbicide.
Background technology
Corn is the main economic crops of current China, the weeds grown in corn field are varied, mainly annual and perennial grassy weed, annual broadleaf weed, common are the rhizome of nutgrass flatsedge, dayflower, field thistle, cottonsedge-like thistle herb, meadow pine, corn sow thistle etc.Be used alone the generation that a kind of weed killer herbicide can not control corn field weed effectively, if weeds easily develop immunity to drugs after continuous administration, herbicide spectrum is narrow.So it is composite to need different cultivars composition to carry out, improves weeding ratio and expand herbicide spectrum.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of corn field herbicide, can weeding ratio be improved, expand herbicide spectrum, save drug cost.
The present invention is by the following technical solutions: a kind of corn field herbicide, the active ingredient of this weed killer herbicide is made up of according to 2-5:5-10:10-20 mass ratio component A, B component and component C, wherein, described component A is thifensulfuronmethyl, B component is mesotrione or sulphur humulone, and described component C is atrazine or pendimethalin.
Preferably, the mass ratio of thifensulfuronmethyl, mesotrione and atrazine is 3:7:15.
The wetting powder composition of this weed killer herbicide and mass percent are: active ingredient 25-35%, wetting agent 5-10%, dispersant 10-15%, filler surplus.
Described wetting agent is lauryl sodium sulfate or neopelex, and described dispersant is sodium lignin sulfonate or sodium alkyl benzene sulfonate, and described filler is kaolin.
Advantageous Effects of the present invention: this corn field herbicide can prevent and kill off the corn field rhizome of nutgrass flatsedge, annual and perennial grassy weed, annual broadleaf weed, to reach the wealthy two object removed of standing grain, have and expand herbicide spectrum, reduction single dose consumption, improve features such as crop safeties.Have special efficacy, three action targets to the malignant weed such as green foxtail, wild broomcorn millet, fiber crops fruit, dayflower, weeds not easily produce resistance.
