Abstract

The invention relates to an insecticide combination containing fenvalerate and omethoate. The weight ratio of the fenvalerate and the omethoate which are effective active ingredients is (0.1-5): (2-55), preferably, (0.5-3): (8-30). According to known technologies in the technical field, conventional additives and filling agents are added into the insecticide combination containing the fenvalerate and the omethoate to be prepared into wettable powders, water dispersing agents, suspending agents, water emulsions or microemulsions.

Description

A kind of Pesticidal combination that contains sumicidin and flolimat

Technical field

The invention belongs to agricultural technology field, relate in particular to a kind of Pesticidal combination that contains sumicidin and flolimat.

Background technology

The agricultural chemicals of all liquid state and the solid-state agricultural chemicals of sizable solvability is arranged in organic solvent for a long time, no matter be insecticide, bactericide or weed killer herbicide, major part is made the form of pulvis or missible oil and is used, but owing to containing in the flying away property of pulvis and the missible oil in a large number to people and animals and the harmful inflammable organic solvent of environment, so that produce poisoning in the process of production, accumulating and use, there is potential safety hazard.Especially in the long-term process of using, the resistance of having made deposits yields reduces drug effect greatly, and a large amount of organic matters evaporate into and caused serious environmental pollution in the air.

The sumicidin insecticidal spectrum is wide, to the natural enemy non-selectivity, to tag with stomach poison function as main, without interior suction and fumigation action, be applicable to the control of insect of cotton, fruit tree, vegetables and other crop, controlling object is coleoptera, diptera, single wing order, Semiptera, Lepidoptera and orthoptera pest, such as corn borer, aphid, pollen beetle, tomato moth, imported cabbageworm, codling moth, apple aphid, cotten aphid, peach fruit borer etc., but invalid to mite.

Rogor is interior absorption organic phosphor desinsection, miticide, the desinsection scope is wide, insect and mite class there be strong tagging and certain stomach poison function, in insect bodies, can be oxidized to active higher omethoate, its mechanism of action is the acetylcholine esterase that suppresses in the insect bodies, hinders nerve conduction and causes death, is applicable to prevent and treat the sucking pest on the various crop, such as aphid, leafhopper, aleyrodid, leaf mining insect and some a red-spotted lizard class good control efficiency is arranged, mite is also had certain preventive effect.

The purpose of this invention is to provide a kind of good drug efficacy, the Pesticidal combination that contains sumicidin and flolimat that consumption is low.

The technical solution adopted for the present invention to solve the technical problems is: a kind of Pesticidal combination that contains sumicidin and flolimat, wherein the weight proportion of effective active composition sumicidin and flolimat is 0.1 ~ 5:2 ~ 55,0.5 ~ 3:8 ~ 30 preferably, the described Pesticidal combination that contains sumicidin and flolimat adds conventional auxiliary agent and fills out agent by technology well-known in the art, makes wetting powder, water dispersant, suspending agent, aqueous emulsion or microemulsion.

The invention has the beneficial effects as follows: a kind of Pesticidal combination that contains sumicidin and flolimat has strengthened than both composite drug effects before, has reduced cost, has enlarged insecticidal spectrum, can either have again miticidal effect by desinsection, safety is improved, and makes simple, with low cost.
