Abstract
A composite insecticide in the form of liquid with high and durable effect, high dispersity and stability, and broad spectrum is prepared from abamectin, high-effect cypermethrin, emulsifier, cosolvent and water. It is suitable for the pests of vegetables.
Description
Technical field
The present invention relates to a kind of agricultural insecticide composition.Particularly be a kind of and plant protection, the broad spectrum insecticide very harmonious close friend of environment.
Background technology
Since 20th century the nineties, the Avermectin that broad spectrum activity is good, the lasting period is long is generally all adopted in the control that is used for the brassicaceous vegetable insect.But owing to behind the Avermectin contact polypide, can not cause that insect dewaters rapidly, desinsection speed is slower, and adding the single agent content of commercially available Avermectin mostly is 1% missible oil or 1.8% above missible oil, and price is than higher.Thereby, influenced the enthusiasm that peasant household uses Avermectin.
Vegetable-crop pest-insect, particularly lepidoptera pest in recent years: cabbage caterpillar, diamond-back moth is big in the various places insect density, harm is rampant day by day, and is very huge to the loss that production and the processing of vegetables causes.
Because of the pesticide resistance of vegetable-crop pest-insect to beta-cypermethrin strengthens year by year, so its control efficiency is barely satisfactory.The first two years, plant protection department once tried to introduce the Phenylpyrazole insecticides fluorine worm nitrile and the chlorfenapyr of import, but because of its ton valency 100,000, hundreds thousand of more than promotion and application in large area.
Simultaneously the vegetables pest control is mostly continued to use old formulation cream preparation, sprays that dosage is big, cost is high, residual height, and the generation of person poultry poisoning's incident is constantly arranged.And, a large amount of organic solvents spray release, cause the serious pollution of the significant wastage and the atmospheric environment of the energy.
Summary of the invention
The purpose of this invention is to provide a kind of efficient, low toxicity, low cost, delay pesticide resistance, drug effect is rapid, residual life is short, to the harmonious close friend's of environment insecticides.With Avermectin, beta-cypermethrin, emulsifier, cosolvent and water, after certain production technology is processed into microemulsion, vegetable-crop pest-insect there is good control efficiency.
The objective of the invention is to realize in the following manner: a kind of insecticides is to be Main Ingredients and Appearance with Avermectin and beta-cypermethrin, adds emulsifier and organic solvent auxiliary agent and the formulated microemulsion of water, and its composition and percentage by weight are as follows:
The composition percentage by weight
Avermectin 0.2～0.8%
Beta-cypermethrin 1.6～6.0%
Emulsifier 20.0～35.0%
Organic cosolvent 5.0～12.0%
Water 40.0～70.0%.
Described emulsifier is made up of No. 601, farming breast and No. 705 mixing of farming breast, and wherein to account for the percentage by weight of whole composition be that the percentage by weight that 10.0～15.0%, 705 emulsifier account for whole composition is 13.0～20.0% to 601 emulsifier.
Described organic cosolvent is mixed by methyl alcohol and dimethylbenzene and forms, and wherein to account for the percentage by weight of whole composition be 2.0～5.0% to methyl alcohol, and the percentage by weight that dimethylbenzene accounts for whole composition is 3.0～7.0%;
After component of the present invention was determined by best proportioning, with Avermectin, beta-cypermethrin and organic solvent auxiliary agent suction modulation kettle, stirring and dissolving was mixed 40 minutes to transparent homogeneous, and suction emulsifier for mixing again adds surplus at last after 30 minutes water fully stirs.With sedimentation in it suction precipitation jar special 12 hours, discharge the bottom precipitation thing after sample examination is qualified,, obtain A Wei beta-cypermethrin microemulsion finished product limpid transparency liquid input liquid filling machine production line packing.
The generation bacterium of Avermectin is a streptomyces griseus in the A Foman streptomycete among the present invention, and makes after cultivation and fermentation by producing bacterium, belongs to novel ten hexa-atomic macrolides antiinsect antibiotics.Insect based on stomach poison function, is had concurrently action of contace poison.After medicament enters polypide, can promote the release of r-aminobutyric acid from nerve endings, hinder the transmission of pest movements nerve signal, make the polypide paralysis, inertia is not got food, until death.Can be used for preventing and treating lepidoptera pests such as vegetable-crop pest-insect such as cabbage caterpillar, diamond-back moth, beet armyworm.
The english common name of Avermectin is; Abamectin, chemical molecular formula C

14Other title has: like to go out, like power mite gram, worm mite light etc. than rhzomorph, acetamiprid, 7051 desinsection elements, avermectin, the evil utmost point.
Beta-cypermethrin belongs to the pyrethroid insecticides of synthetic among the present invention, and it is that invalid body in 8 isomer in the cypermethrin technical material is become active isomer through the isoversion transposition, and desinsection is renderd a service higher about 1 times than cypermethrin.Insect is had very strong tagging and stomach poison function, and the nerve conduction that makes insect is blocked and strenuous exercise, the spasm of body are occurred, and paralysis is dead at last.Ovum to some lepidoptera pest has certain lethal effect simultaneously.Knockdown effect is strong, desinsection speed is fast, insecticidal spectrum is wide, can be widely used in the control of insect on cotton, vegetables, fruit tree, tobacco, the Soybean and Other Crops.
The english common name of beta-cypermethrin is: beta-cypermethrin.
Chemical name is: (IR cis) S and (IS cis) R-a-cyano group-(3-phenoxy group)-3-C-2,2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester.
Chemical molecular formula: C

Other trade name has: annihilate, defend that evil is clean, height goes out spirit, unmatched powder etc.
The present invention has following characteristics:
1, the present invention is mixed with microemulsion with Avermectin and beta-cypermethrin, organic solvent auxiliary agent, water, and its co-toxicity coefficient is estimated the synergy highly significant.After two effective ingredients are composite, integrate both advantages: drug effect is rapid, the lasting period is long, delay pesticide resistance, reduced use cost, insecticidal spectrum is wider, realistic production application.
2, said preparation belong to thermodynamics through the time stable dispersion, the agricultural chemicals dispersity is high, reaches the miniaturization degree, the agricultural chemicals particle is generally 0.01～0.1 micron.Dispersed better in water, stronger to the target body permeability, the attached plant surface energy is better, so drug effect lasting stability more.
3, this formulation is by the liquid pesticide effective ingredient, surfactant (emulsifier), and organic solvent auxiliary agent and water are formed.With water is medium, do not contain or contain organic solvent less, thereby do not fire not quick-fried, production operation, storing safely, save a large amount of organic solvents, environmentally friendly harmony simultaneously.
4, this formulation belongs to liquid pesticide formulation non-solvent formulation, is rising novel form, and the trend that replaces traditional missible oil is gradually arranged, and extensive market prospects is arranged.
Experimental result of the present invention is as follows:
(1) to rat acute per os LD
50:
♂: 926mg/kg belongs to low toxicity
♀: 794mg/kg belong to low toxicity (2) to rat acute through skin LD
50:
♂:＞2000mg/kg belongs to low toxicity
♀:＞2000mg/kg belongs to low toxicity
(3) rabbit skin excitant: 1,24,48 and 72 hours integrations are: 2,3,2.5,2 minutes, and to skin moderate excitant.
(4) lagophthalmos stimulates: it is 12 minutes that 1 hour lagophthalmos stimulates integral exponential (I, A, O, I).The average index (M, I, O, I) of lagophthalmos stimulation in 48 hours is 5 minutes.Eye there is slight stimulation.
(5) guinea pig skin allergy: belong to weak sensitization class agricultural chemicals.
(6) control diamond-back moth, cabbage caterpillar effect
Effect was remarkable when said preparation was prevented and treated diamond-back moth, cabbage caterpillar on brassicaceous vegetable, and the result equates with demonstration test, and demonstration test the results are shown in following table:
