Abstract

The invention discloses a compound herbicide. The compound herbicide comprises the following active components according to the mass ratio of (1-5):(10-20):(10-20): a component A (nicosulfuron), a component B (propisochlor or butachlor) and a component C (atrazine). The compound herbicide comprises the following wettable powder components by mass percent: 30-40% of the active components, 1-6% of a wetting agent, 5-10% of a dispersant, and the balance of a filler. The compound herbicide has part of synergistic effect on broadleaf weeds in corn fields, has an additive effect on grassy weeds, is safe to corn, does not adversely influence the corn growth, has a relatively good control effect on annual weeds, such as barnyard grass, setaria viridis, dungweed and nightshade, and can improve the control efficiency, expand the weed control spectrum, reduce the consumption of the active components, lower the use cost and reduce environmental pollution.

Description

A kind of complex weedicide

Technical field

The invention belongs to technical field of pesticide, specifically a kind of complex weedicide.

Background technology

The weeds grown in current corn field are varied, be used alone the generation that a kind of weed killer herbicide can not control corn field weed effectively, defect in various degree is often there is in the weed killer herbicide kind containing single-activity component on Agriculture Field control of weeds, as after continuous administration, weeds easily develop immunity to drugs, herbicide spectrum is narrow, and application times is many can weighting ring environment pollution.Different cultivars composition carries out composite, is the important means that the modal method of control resistant weed becomes integrated control weeds in field.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of complex weedicide, can preventive effect be improved, expand herbicide spectrum, reduce the consumption of active ingredient, save drug cost.

The present invention is by the following technical solutions: a kind of complex weedicide, active ingredient is made up of according to 1-5:10-20:10-20 mass ratio component A, B component and component C, wherein, described component A is nicosulfuron, B component is propisochlor or butachlor, and described component C is atrazine.

Preferably, the mass ratio of nicosulfuron, butachlor and atrazine is 2:10:20.

The wetting powder of this weed killer herbicide becomes to be grouped into and mass percent is: active ingredient 30-40%, wetting agent 1-6%, dispersant 5-10%, 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 complex weedicide has part synergistic effect to broad leaved weed in corn field, has summation action to grassy weed, to corn safety, growth, without impact, has favorable effect to annual weed such as barnyard grass, green foxtail, lamb's-quarters, black nightshades.Can preventive effect be improved, expand herbicide spectrum, reduce the consumption of active ingredient, save drug cost, reduce environmental pollution.
