Abstract
The present invention relates to a binary pesticide composition made up by mixing abamectin with chlorpyrifos, the abamectin, chlorpyrifos, solvent, emulsifier and penetrant can be made into emulsifiable solution powder, wettable powder or micro emulsion. Said composition possesses high insecticidal effect, low cost, can make pests delay production of drug-resistance, and has special control effect for pear psyllid, at the same time it can be used for controlling other pests, such as thrips, aphid, imported cabbageworm, diamondback moth, aleyrodids, peach fruit borer and red mite, etc.
Description
The present invention relates to a kind of composition pesticide, relate to a kind of insecticides specifically.

3NO
3PS, other title: termite is clear, Lan Zhu, Le Siben kills worm, Tai Lekai, Tao Sisong.) belong to organophosphorus compounds broad spectrum disinfestation, miticide, have tag, stomach poison function.Be applicable to insect and mite class on the various crop such as control citrus, cotton, corn, apple, pears, paddy rice, peanut, soybean, wheat and tea tree.Chlopyrifos is degraded easily in environment, and environmentally safe, the lasting period is longer.
Pear sucker belongs to Homoptera, Psyllidae.Pear sucker distributes general, but comparatively common with northern pears district.The pear sucker feeding habits are more single, the leaf of pear tree sheet of mainly causing harm, and thorn is inhaled juice, and the blade rate of being injured can reach more than 70%, the blade elder generation blackening of being injured, petiole shortens, last withered coming off, little with fruit in season deformation, shade deviation influences commodity value.The pear tree untimely defoliation owing to be injured is caused depauperation, so that influence the output in the coming year.And nymph secretes a large amount of honeydew mucus on blade, lead to dark mildew, increases the weight of the fallen leaves of pear tree, influences the result quantities in the coming year.According to data, because causing harm of pear sucker causes the underproduction of pears very serious, the average underproduction 17～18%, every approximately 667m
2The output value reduce 680～720 yuan.At present, it is clean that the medicament of control pear sucker mainly contains wood louse, and still, medicament is single to be easy to make insect to develop immunity to drugs, and therefore, is necessary to study new medicament.
It is a kind of to pear sucker effectively preventing method that purpose of the present invention provides, and enlarges the control spectrum of Avermectin and chlopyrifos, improves their preventive effect.
Below narrate main contents of the present invention:
Avermectin chlorpyrifos pesticide composition is characterized in that containing Avermectin and chlopyrifos.
The formulation that insecticides of the present invention can be prepared according to method known in those skilled in the art is missible oil, pulvis, wetting powder, microemulsion.
Be example explanation the invention process method with missible oil of the present invention below:
Insecticides missible oil of the present invention is formed by Avermectin, chlopyrifos and solvent, bleeding agent and emulsifier assembly system, and wherein the percentage by weight of various components is:
Avermectin 0.1～5%
Chlopyrifos 10～50%
Emulsifier 5～25%
Solvent 10～70%
Bleeding agent 0.5～20%
Solvent described in the cream preparation of the present invention is any one in toluene, dimethylbenzene, acetone, dimethyl formamide and the solvent known in those skilled in the art.
Emulsifier described in the cream preparation of the present invention is 0201,500
#, 602,2201,700
#, any two or three in Tween-80, Tx-10 and the emulsifier known in those skilled in the art composition.
Bleeding agent described in the cream preparation of the present invention is any one in diesel oil, azone, machine oil, peregal, JFC and the emulsifier known in those skilled in the art.
Beneficial effect of the present invention: (1), this insecticides have special control efficiency to pear sucker; (2), enlarged the control spectrum of Avermectin and chlopyrifos: except that to the pear sucker, other insect on vegetables, fruit tree, the cotton such as thrips, vegetable aphid, cabbage caterpillar, diamond-back moth, aleyrodid, scale insect, peach fruit borer, two spotted spider mite, cotton bollworm, pink bollworm etc. are all had preventive and therapeutic effect.(3), evidence, the advantage that the present composition has is efficient, quick-acting, the lasting period is long.
