Abstract
The pesticide composition mainly comprises imidacloprid and chlorpyrifos, which is uniformly mixed with solvent, emulsifier and penetrant, and can be make into emulsifiable solution, powder, wettable powder or micro emulsion. Said pesticide composition is high in insecticidal effect, low in toxicity and strong in systemic property, possesses special control effect for apple aphid, at the same time it also can be used for controlling other pests, such as thrips, aphid, imported cabbageworm, diamondback moth, aleyrodids, scale louse, peach fruit borer, red mite and others.
Description
The invention belongs to pesticide field, relate in particular to a kind of insecticides.

3PS, other title: termite is clear, Lan Zhu, Le Siben kills worm, Tai Lekai Tao Sisong) belongs to organophosphorus compounds broad spectrum disinfestation, miticide, have tag, stomach poison function.It is 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.
Imidacloprid and chlopyrifos are mainly used with single agent form, make the insecticidal spectrum relative narrower, and insect is easy to generate pesticide resistance.The synergistic complex of agricultural chemicals is the control spectrum that enlarges pesticide species, saves the method for medication, also is the measure that prevents that insect from developing immunity to drugs.From the patent application situation, the patent of invention of Zhejiang Zhang Aen " a kind of composition pesticide and preparation method thereof " is the binary mixture preparation of Imidacloprid and Avermectin; The patent of invention " a kind of first woods paste insecticide " of Guangxi Science ﹠ Technology Consultative Centre's application is Imidacloprid and methylamine squama binary mixture preparation; The patent of invention of Agricultural University Of Nanjing " compound method of a kind of cyhalothrin, chlorpyrifos mixture " is the binary mixture preparation of cyhalothrin and chlopyrifos; The patent of invention of Agricultural University Of Nanjing " a kind of insecticide " is chlopyrifos, parathion-methyl and phoxim ternary mixture preparation.Up to now, still find no the report that closes Imidacloprid and chlopyrifos composition.
Wooly aphis (Eriosoma lanigerum Hausmann) is distributed in all over the world, is mainly apple the host plant of China, secondly also has Siberian crabapple, Malus spectabilis and premium.Wooly aphis is located parasitism with hollow and underground root of aptery viviparous adult and the intensive healing of wound the in the shade limb of apple tree of nymph, the Ye Qunzhong that cuts saw kerf, young sprout, axil, fruit spur end, carpopodium, calyx or the rhizosphere etc. that exposes the face of land and causes harm, draw juice, consume fruit tree nutrition, had a strong impact on growing and the differentiation of bud of apple tree, make tree vigo(u)r weak, the age of tree shortens, and yield and quality reduces.Simultaneously because breaking of insect gall causes the invasion and attack of other damage by disease and insect, easily as the generation of apple tabaniformis and apple canker etc.Heavier orchard is taking place, and the wooly aphis fruit of also causing harm can make it all be ruined when treelet is injured.At present, wooly aphis still there is not the effectively preventing method.
The objective of the invention is to Imidacloprid and chlopyrifos are carried out synergistic complex,, reduce cost of use, delay insect it is developed immunity to drugs, especially provide a kind of effective method for the control wooly aphis to enlarge their control spectrum.
Below narrate main contents of the present invention:
Imidacloprid chlorpyrifos pesticide composition is characterized in that containing Imidacloprid and chlopyrifos.
The formulation that insecticides of the present invention can be processed according to the method for well known to a person skilled in the art is missible oil, pulvis, wetting powder, microemulsion.
Be that example is described in detail implementation method of the present invention below with the cream preparation:
Insecticides missible oil of the present invention, it is by Imidacloprid and chlopyrifos, and solvent, emulsifier, bleeding agent are formulated, and the percentage by weight of various components is in the cream preparation:
Imidacloprid 0.1～5%
Chlopyrifos 10～40%
Emulsifier 5～25%
Solvent 10～70%
Bleeding agent 0.5～20%
Emulsifier described in the invention described above cream preparation is 0201,500
#, 6202,2201,700
#, Tween-80, Tx-20 and emulsifier known in those skilled in the art any two or three.
Solvent described in the invention described above cream preparation is any one of toluene, dimethylbenzene, acetone, dimethyl formamide and solvent known in those skilled in the art.
Bleeding agent described in the invention described above cream preparation be diesel oil, azone, machine oil, peregal, JFC and bleeding agent known in those skilled in the art any one.Bleeding agent is mainly used in the raising drug effect.
The compound method of cream preparation of the present invention is those skilled in that art's known method: soon Imidacloprid, chlopyrifos are dissolved in the corresponding solvent, add bleeding agent, emulsifier again, stir, and promptly get insecticides cream preparation of the present invention.
Beneficial effect of the present invention: (1), insecticides of the present invention have special control efficiency to wooly aphis, when insecticides 1000-2000 of the present invention doubly uses, demonstrate after 48 hours the wooly aphis control efficiency is reached more than 90%, the 15th day control efficiency to wooly aphis still reaches more than 63% behind the medicine; (2), enlarge the control spectrum of Imidacloprid and chlopyrifos, synergistic effect is remarkable: Imidacloprid and chlopyrifos are the Pesticidal compositions that a kind of novel nitro-methylene-type and organophosphorus compounds pesticide compositional form, the pesticide compositional that belongs to different mechanism of action types, many to the insect action site, except being used to prevent and treat the wooly aphis, also can be used for preventing and treating thrips on vegetables, fruit tree, the cotton, vegetable aphid, cabbage caterpillar, diamond-back moth, aleyrodid, scale insect, peach fruit borer, two spotted spider mite, cotton bollworm, pink bollworm insect; (3), evidence, the advantage that the present composition has is efficient, quick-acting, the lasting period is long.
