Abstract
The invention discloses an aqueous emulsion containing pesticide Chlorfenapyr, and is characterized in that the aqueous emulsion takes the components with the weight percentage as the raw materials: 0.1-50% of Chlorfenapyr, 1-50% of solvent, 1-30% of emulsifier, 0.1-1% of thickening agent, 0.5-5% of antifreeze and 0.1-1% of defoamer, and the water is supplemented to be 100%. After the formulation is filtered by a plurality of times of experiments, the optimal ratio of the components is 1%-15%. Compared with missible oil, the preparation formulation is little in residua for crops, so as to fundamentally solve the problems of low flash, unsafe storage, high cost and easy phytotoxicity, thus having certain advantages of safety and environmental protection. The desinsection aqueous emulsion containing Chlorfenapyr can be widely applied to diamond back moth, corn earworm, woodborer and Lepidoptera with resistance on vegetables, cotton, fruit trees and paddy, and has remarkable control effects.
Description
Technical field:
The present invention relates to a kind of disinsection aqueous emulsion that contains chlorfenapyr, particularly a kind of plant protection disinsection aqueous emulsion that contains chlorfenapyr.
Background technology:
The kind of the insecticide that protective plant is used is a lot, generally adopts missible oil and wetting powder.The organic solvent that well-known missible oil contains is easy to volatilize, catches fire, harmful poisonous to human body and plant, contaminated environment, transportation is not easily, and simultaneously, wetting powder has a large amount of dust in producing, using, exist too to face contaminated environment, influence operating personnel's health.
Summary of the invention:
The present invention has overcome shortcoming of the prior art, provides that a kind of to have a safety and environmental protection efficient, contains the disinsection aqueous emulsion of chlorfenapyr.
In order to solve the problem of above-mentioned technology, the present invention is achieved by the following technical solutions, the aqueous emulsion that bath emulsion is made up of chlorfenapyr, emulsifier, antifreeze, defoamer, solvent, thickener and water of counting that contains chlorfenapyr, it forms content (is 100% in aqueous emulsion weight): chlorfenapyr: 0.1%～50%, chlorfenapyr 0.1%～50%, solvent 1%～50%, emulsifier 1%～30%, thickener 0.1%～1%, antifreezing agent 0.5%～5%, defoamer 0.1%～1%, wherein water is supplemented to 100%.
The present invention compares with the insecticide emulsifiable concentrate that contains chlorfenapyr, and aqueous emulsion is owing to contain or only contain a little poisonous inflammable aromatic hydrocarbon solvent, thus can avoid producing with storage and transport process in inflammable and explosive phenomenon.This formulation does not have unpleasant poisonous smell, and is little to eye irritation, reduced the pollution to environment, improved greatly producing accumulating and user's safety.In addition, aqueous emulsion is a matrix with the water of cheapness, and the emulsifier consumption is 1%～30%, and is approximate with missible oil.Though increased auxiliary agents such as some emulsifier, antifreeze, on economic benefit, can compete with corresponding missible oil.It is bigger than missible oil that aqueous emulsion sprays droplet, after vestiges that stay after not having wetting powder to squirt and missible oil use, and fruit powder phenomenon such as come off.Existing many evidences, the drug effect of aqueous emulsion is suitable in the corresponding missible oil with dosage, and the toxicity of warm blooded animal is reduced greatly, and is good with the wettable of other medicaments such as suspending agent or liquid fertilizer.
