Description

Pesticide composition and application thereof Technical Field The invention belongs to the technical field of pesticide and discloses a pesticide composition and application thereof. Background Dimpropyridaz is a pyrazoloamide pesticide with novel action mechanism developed by Pasteur, is mainly used for field crops such as fruit trees, vegetables, soybeans, cotton, grains, potatoes and the like, flowers, ornamental plants and the like, and is high in efficiency for preventing and controlling pests such as lepidoptera, coleoptera, diptera (flies, mosquitoes, vegetable spot-shaped flies and the like), hemiptera, thysanoptera and the like, and especially sucking mouthparts pests such as aphids, whiteflies, psyllids and the like. The chemical method for controlling the pests has the advantages of high efficiency, rapidness, simple and convenient operation, low cost and the like, can rapidly control the pest spreading by poisoning, inhibiting or interfering the physiological metabolism of the pests, and can realize emergency control especially in large-scale outbreak. The broad spectrum can act on various pests at the same time, and the medicament has various dosage forms (such as spraying, fumigation and the like) so as to adapt to the requirements of different scenes. However, this method also has significant drawbacks of environmental pollution (pesticide residue contaminates soil, water sources and food chains), drug resistance development (prolonged use leads to increased pest adaptability), non-target biocidal (miskilling beneficial insects and natural enemies, destroying ecological balance), and residual hazards (threatening human health). Therefore, the low-toxicity high-efficiency medicament is scientifically selected and applied regularly so as to balance the control effect and the environmental sustainability. Disclosure of Invention In order to solve the problems, dimpropyridaz is scientifically combined with any one of the compound of the formula I and the compound of the formula II with different action mechanisms, and targets for effective control and reasonable compounding proportion are screened, so that the control effect can be remarkably improved, the insecticidal spectrum is expanded, the single resistance development probability of pests is reduced through the action of multiple targets, the cost is reduced, and the comprehensive advantage of scientific medication is embodied. In order to achieve the aim, the invention adopts the following technical scheme that the pesticide composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is dimpropyridaz, and the active ingredient B is a compound shown as a formula I: (formula I) or formula II: In the formula II, the mass ratio of the active ingredient A to the active ingredient B is 80:1-1:80. Further, the active ingredient B is a compound shown in a formula I, and the mass ratio of the active ingredient A to the active ingredient B is 1:50-40:1 or any value in the numerical range. Further, the active ingredient B is a compound of the formula II, and the mass ratio of the active ingredient A to the active ingredient B is 1:40-60:1, or any value in the numerical range. Further, the active ingredient B is a compound shown in a formula I, and the mass ratio of the active ingredient A to the active ingredient B is 1:50-20:1 or any value in the numerical range; Further, the active ingredient B is a compound of formula I, and the mass ratio of the active ingredient A to the active ingredient B is 1:35-20:1, or any value in the numerical range. Further, the active ingredient B is a compound of the formula II, and the mass ratio of the active ingredient A to the active ingredient B is 1:22-40:1, or any value in the numerical range. Further, the pesticide composition comprises an auxiliary component acceptable in pesticide besides the active component, wherein the auxiliary component is selected from one or more of wetting agents, dispersing agents, emulsifying agents, thickening agents, disintegrating agents, antifreezing agents, antifoaming agents, solvents, preservatives, stabilizers, synergists or carriers. Further, the pesticide composition is prepared into a solid preparation or a liquid preparation. Further, the solid preparation is water dispersible granule and wettable powder, and the liquid preparation is suspending agent, emulsifiable concentrate, aqueous emulsion, microemulsion and dispersible oil suspending agent. The invention also discloses the application of the pesticide composition in controlling crop pests. Further, the pests are lepidoptera pests or hemiptera pests; Further, the lepidoptera pests are asparagus caterpillar, plutella xylostella, cabbage caterpillar and rice stem borer, and the hemiptera pests are rice planthoppers. The beneficial effects of the invention are as follows: 1) The pesticide composition disclosed by the invention is reasonably compounded through pesticides wit
