Abstract
The invention discloses an acaricidal composition containing active ingredients, namely chlorine chlorfenapyr and spirodiclofen. The weight ratio of the chlorine chlorfenapyr to the spirodiclofen is (1-30) to (1-30), and the total weight of the active ingredients accounts for 1%-60% of that of the composition. The acaricidal composition provided by the invention is prepared into wettable powder, water dispersible granules, suspending agent, suspoemulsion and microcapsule suspension according to a universal technology in the field. The acaricidal composition is used for preventing red spiders, polyphagotarsonemus latus, tetranychus cinabarinus boisdu and tetranychus urticae koch, and further can be used for preventing mites on fruit trees, vegetables and cotton. The acaricidal composition has the advantages that firstly, the synergism is remarkable, wherein the chlorine chlorfenapyr and the spirodiclofen are blended with each other without conflict, so that the synergism can be adjusted, the dosage of the composition can be reduced, and the cost can be reduced; secondly, by virtue of double action mechanisms of the compounded two acaricide, the insecticide resistance of the mites is delayed; and thirdly, an insecticidal spectrum is expanded, wherein the application range of the composition is enlarged, and the composition is suitable for a plurality of mites on the fruit trees, the vegetables and the cotton.
Description
Technical field
The present invention relates to the chlorine chlorfenapyr and spiral shell mite ester is the miticide composition of active ingredient.
Background technology
The chlorine chlorfenapyr, chemical name is 4-bromo-2-(4-chlorphenyl)-1-[(2-chloroethoxy) methyl]-5-trifluoromethyl pyrpole-3-formonitrile HCN, be the new pyrrole heterocycle compound with obvious pesticide and miticide actility that Hunan Chemical Research Institute designs and synthesizes.
Its structural formula is:
The chlorine chlorfenapyr is the analog of new type disinsection miticide chlorfenapyr.Thereby its mechanism of action is by disturbing Intramitochondrial electrochemical gradient blocking oxide phosphorylation process.Through result of the test show noval chemical compound chlorine chlorfenapyr have excellent tag, stomach poison activity and comprehensive toxic action, its toxicity is low, safety is good, without cross resistance.
Spiral shell mite ester (Spirodiclofen) chemical name be 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro [4,5]-last of the ten Heavenly stems-3-alkene-4-base-2,2-dimethyl butyrate acid esters.Its structural formula is for being:
The mechanism of action is the Fatty synthesis that suppresses in the pest mite body.Spiral shell mite ester has tags and stomach toxicity, without interior absorption.It is wide that it kills mite spectrum, the ovum children holds concurrently and kills, lasting period length, low toxicity, low-residual, safety are good, and other miticides without cross resistance.Shortcoming is that its quick-acting is poor, to becoming the mite effect undesirable.Use with existing miticide, both can improve its quick-acting, be conducive to again the resistance management of mite evil.
