Abstract
The present invention relates to a kind of broad-spectrum built pesticide and manufacture method thereof, it is characterized in that with double solvents solution being made in the dissolving of the former powder of sevin, same again methamidophos from crude oil, cypermethrin crude oil are miscible, add behind the emulsifier formulated.This compounded pesticides synergy is remarkable, and is lower to the person poultry toxicity to crop safety, can be widely used in the control of insect on the various crop.The present invention also has simple for process, and is with low cost, easy to use, and characteristics such as economic benefit height are suitable for promoting the use of.
Description
The present invention relates to a kind of broad-spectrum built pesticide and manufacture method thereof.
Acephatemet (methamidophos) is a high-efficient broad-spectrum insecticide commonly used, but owing to the high application that has limited on crops such as fruit tree, vegetables of its toxicity; Cypermethrin (cypermethrin) is also famous with high-efficiency broad spectrum, but owing to developing rapidly of pest resistance to insecticide threatening its service life; Sevin (carbaryl) is one efficient, low toxicity, broad spectrum activity old farmer medicine kind, once is extensive use of at the seventies, and recent two decades is stopped using basically because of the development of pest resistance to insecticide and the factors such as formulation characteristic of itself in the back.More than three kinds all have many producers formally to register in China.In the preparation registration, acephatemet is 50% cream preparation, and cypermethrin is 10% cream preparation, and sevin is 25% wetting powder.And sevin also has a suspension complex preparation, by the registration of Zichuan, Shandong Liu Quan insecticide factory and chemical plant, Xinji City, Hebei produce (The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC: " and newly organized agricultural chemicals handbook, 1989, agriculture publishing house, P.33～36,90～93,148～151; " agriculture chemical registration bulletin ", 1992; 1993).Measured through us in recent years, many insects have recovered susceptibility to sevin again, find that simultaneously itself and acephatemet, cypermethrin have obvious role in synergism, thus these several medicaments have been carried out composite research, and sevin has been joined into cream preparation.
The purpose of this invention is to provide that a kind of synergy is remarkable, insecticidal effect is high, cheap, easy to use, toxicity is lower, the simple ternary built insecticidal emulsifiable concentrate of technology preparation.
This broad-spectrum built pesticide is formulated by acephatemet (methamidophos) crude oil, the former powder of sevin (carbaryl), cypermethrin (cypermethrin) crude oil, double solvents and emulsifier, and each proportioning components (percentage by weight) is as follows:
Methamidophos from crude oil 10～30%
The former powder 5～15% of sevin
Cypermethrin former turbid 0.5～3%
Double solvents 40～73%
Emulsifier 8～15%
Wherein contained component of double solvents and proportioning (percentage by weight) are as follows:
Dimethyl sulfoxide (DMSO) 3～15%
Dimethylbenzene 20～40%
Industrial alcohol 30～70%
Ethyl acetate 3～10%
Wherein emulsifier is 656H and OP-10, and the two proportioning by weight is 4～8: 1～4.
The manufacture method of this broad-spectrum built pesticide may further comprise the steps:
A, preparation double solvents add the former powder of sevin in reactor, heated and stirred makes its dissolving;
B, add methamidophos from crude oil, cypermethrin crude oil and emulsifier in above-mentioned steps gained solution, heated and stirred is even, promptly gets broad-spectrum built insecticidal emulsifiable concentrate preparation.
Wherein the heating-up temperature in steps A is 55～60 ℃, and mixing time is 40 minutes; Heating-up temperature in step B is 40～45 ℃, and mixing time is 30 minutes.
Advantage of the present invention and good effect are as follows:
1. synergy is remarkable, insecticidal spectrum is wide, preventive effect is good, and can tackle resistant insect.
2. simple, with low cost, the no three wastes of manufacturing process produce.
3. easy to use, toxicity is lower, to crop safety, be suitable for promoting the use of.
Accompanying drawing is a compound insecticidal missible oil technological process of production block diagram.
The present invention can provide by following embodiment:
Embodiment one: give successively to add dimethyl sulfoxide (DMSO) 15Kg, dimethylbenzene 52.5Kg, industrial alcohol 75Kg, ethyl acetate 7.5Kg in the 500 liter reactors; Stirring is warming up to 60 ℃, drops into the former powder of sevin (purity 95%) 28.4Kg; Constant temperature stirred after 40 minutes, added methamidophos from crude oil (purity 73%) 82.2Kg, cypermethrin crude oil (purity 90%) 3.33Kg, 656H 25.7Kg, OP-10 10.3Kg; Be warming up to 45 ℃, constant temperature stirs shut down in 30 minutes, promptly got 30% compounded cream preparation 300Kg.
Embodiment one products obtained therefrom can form milky emulsion after adding entry, and the conventional spray method uses back moistening plate-out ability on crop leaf good, belongs to medium pesticide.Except that can preventing and treating cotton bollworm, cotten aphid effectively, also can be used for insects such as the multiple Lepidoptera of control, coleoptera, Homoptera, Semiptera and mite class on other crop in the production.General diluted concentration is 1000～2500 times during use, and control efficiency can reach more than 90%, and the longevity of residure is about 7-12 days.
Embodiment two: method is with embodiment one.Various raw material additions are: dimethyl sulfoxide (DMSO) 13.4Kg, dimethylbenzene 46.9Kg, industrial alcohol 67Kg, ethyl acetate 6.7Kg, the former powder 39.5Kg of 95% sevin, 73% methamidophos from crude oil 82.2Kg, 90% cypermethrin crude oil 8.33Kg, 656H 20Kg, OP-10 16Kg make 35% compounded cream preparation 300Kg at last.
The fundamental characteristics of embodiment two products obtained therefroms is identical with embodiment one product, and toxicity does not also obviously strengthen, but pest controling effect is increased, and particularly homoptera pest such as cotten aphid and mite class drug effect is had obvious enhancing.Dilution is 1200～3000 times during general the use, and control efficiency can reach more than 90%.About 8-13 of the longevity of residure days.
Embodiment three: method is with embodiment one.Various raw material additions are: dimethyl sulfoxide (DMSO) 12.5Kg, dimethylbenzene 59.5Kg, industrial alcohol 92Kg, ethyl acetate 8Kg, the former powder 26.3Kg of 95% sevin, 73% methamidophos from crude oil 54.8Kg, 90% cypermethrin crude oil 11.1Kg, 656H 18Kg, OP-10 18Kg make 25% compounded cream preparation 300Kg at last.
The fundamental characteristics of embodiment three products obtained therefroms is identical with embodiment one product, though total effective component content decreases, preventive effect is still very high.Dilution is 1000～2500 times during general the use, and control efficiency can reach more than 90%, about 8～11 days of the longevity of residure.
