Abstract

The invention relates to the field of pesticides, and provides a compound pesticide. The formula of the compound pesticide contains the following components in part by weight: 1 to 60 parts of thiacloprid, 0.1 to 20 parts of abamectin and the balance of aids and filler. The compound pesticide disclosed by the invention has a broader prevented and controlled spectrum, and can be used for treating a variety of pests and mites on fruit trees, vegetables, soybeans, peanuts, cotton, corns, wheat and other crops in one pesticide application.

Description

A kind of composite insecticide

Technical field

The present invention relates to pesticide field, relate to a kind of composite insecticide particularly.

Background technology

Because insecticide thiophene worm quinoline is efficient to the sucking mouth parts insect, relatively poor to other mouthpart insect effect, and the control spectrum is narrower, selects the effect with synergy or expanding prevention spectrum composite with it of suitable insecticide, can be used for insect and administer, meet the requirement of modern agricultural development.

Summary of the invention

(1) technical problem that will solve

The composite insecticide that the purpose of this invention is to provide a kind of mechanism of action complementation, low toxicity, low-residual, has wider control spectrum.

(2) technical scheme

A kind of composite insecticide of the present invention, the prescription of described composite insecticide is as follows: by weight, comprise following component:

Thiophene worm quinoline 1-60 part

Avermectin 0.1-20 part

All the other are auxiliary agent and filler.

Wherein, add the Tebuconazole bactericide in the described composite insecticide, it accounts for the 0.1-20% of gross weight.

Wherein, the preferred content of active ingredient thiophene worm quinoline and Avermectin is 2-80% in the described composite insecticide.

Wherein, the preferred content of described composite insecticide active ingredient thiophene worm quinoline and Avermectin is 10-50%.

Wherein, described Avermectin substitutes with Affirm (Merck Co.).

Wherein, utilize above-mentioned said composite insecticide, be equipped with known auxiliary agent of those skilled in the art and filler, can process formulation is missible oil, aqueous emulsion, microemulsion, water or oil-suspending agent, wetting powder or water dispersible granules.

(3) beneficial effect

Composite insecticide of the present invention compared with prior art has following advantage:

The one, increase quick-acting.Thiophene worm quinoline quick-acting is fast, and abamectin pest killing speed is slower, but the lasting period is long, the mixture that both are re-dubbed, and existing quick-acting has lasting effect again.

The 2nd, increase the mode of action to insect.Thiophene worm quinoline is based on interior suction, and based on stomach poison function, both are composite with strong complementarity to insect for Avermectin.

The 3rd, delay insect and produce drug resistance.Because of nicotinoids agricultural chemicals such as thiophene worm quinoline easily develop immunity to drugs, and the abamectin pest killing mechanism of action is special, and does not have cross resistance between the nicotinic insecticide such as thiophene worm quinoline, and the mixture that is re-dubbed with it can delay insect and produce drug resistance.

Thiophene worm quinoline and Avermectin or Affirm (Merck Co.) be composite to have technical advantages such as significantly efficient, low toxicity, wide spectrum.A drug can doublely be controlled two or more primary pests, and the lasting period can be equivalent to above routine administration twice, and to the pest natural enemy gentleness, no cross resistance.Therefore, saving of labor, economy, society and environmental benefit are all very remarkable, are the desirable insecticides of producing the green non-pollution agricultural product.

Composite insecticide of the present invention, because thiophene worm quinoline and Avermectin all have complementary preferably, Zu He composite insecticide thus, sucking mouth parts, pests with chewing mouthparts all there is the better prevention effect, the control and double the controlling that can be used for the insects such as aphid, plant hopper, leafhopper, beet armyworm, cotton bollworm, two spotted spider mite of field crop, this insecticide good drug efficacy, cost is low, the control spectrum is wide, toxicity is low, to crop safety.Insect, evil mite are planted by a drug that can be used for various crop such as fruit tree, vegetables, soybean, peanut, cotton, corn, the wheat Zhiduo County of can holding concurrently.
