Abstract
A kind of compound organophosphorus insecticide that contains efficient, the low toxicity of organic phosphor, emulsifier, solvent, stabilizing agent, have that production technology is easy, toxicity is lower, safe in utilization, residual low in crops, the advantage that insects such as various aphid mites, oriental tobacco budworm, fruit tree budworm, corn borer, rice fulgorid, rice leaf roller is all had preventive and therapeutic effect, in use the method for available sprinkling not only also can be used sprinkling poisoned soil method, stem brush method.
Description
The present invention relates to compound organophosphorus insecticide, more detail is a kind of by acephatemet, Rogor, emulsifier, stabilizing agent etc. be mixed having of forming the desinsection scope be wide, low toxicity compound organophosphorus insecticide efficiently.
The insect of control sucking mouth parts and biting mouthparts on agricultural as paddy rice, wheat, corn, peanut, soybean, fruit tree aphid mite etc., generally is to prevent and treat with omethoate emulsifiable solution, phoxim emulsifiable concentrate, Rogor at present.Have working concentration higher, insect easily develops immunity to drugs, and sprinkling personnel poison easily, and agricultural chemicals is in the residual more high shortcoming of crops.Especially to oriental tobacco budworm, the cigarette aphid mite of harm tobacco leaf, the flolimat that uses is residual higher at present.
Present inventors are in order to solve the weak point of above-mentioned agricultural chemicals, through studying with keen determination, the compound organophosphorus insecticide that discovery obtains after being mixed with acephatemet, Rogor, emulsifier, stabilizing agent, organic solvent has efficient, low toxicity, the advantage of broad spectrum activity has so far been finished the present invention.
The purpose of this invention is to provide a kind of be used to the prevent and treat oriental tobacco budworm of tobacco, efficient, the low toxicity of cigarette aphid mite, basic noresidue, the compound organophosphorus insecticide of broad spectrum activity.
It is easy that second purpose of the present invention provides a kind of production technology, and easy to use and safety is lower-cost to all medicative compound organophosphorus insecticide of fruit tree budworm, corn borer, rice fulgorid, rice leaf roller.
In order to achieve the above object, the present invention is achieved in that
In the enamel reacting dose, add:
(a) weight concentration is the acephatemet of 8-14%;
(b) weight concentration is the Rogor of 26-32%;
(c) weight concentration is the emulsifier of 5-15%;
(d) weight concentration is the urea of 0.5-10%;
The rest is organic solvent, dimethylbenzene, toluene.
The emulsifier of Shi Yonging in the present invention, use be that surfactant by cationic, anionic and nonionic is mixed and forms.
In order to make medicament stable in storage, use, purpose of the present invention can also be found by add urea in medicament.
The present invention's compound organophosphorus insecticide is difficult for using with alkaline agricultural chemicals, chemical fertilizer, to prevent to reduce pesticide supplying effect.
Compound organophosphorus insecticide of the present invention is toxic lower, safe in utilization, residual low in crops, the multiple insect that harms the crops all there is preventive and therapeutic effect, not only the method for available sprinkling is used, also available sprinkling poisoned soil method, stem brush method, advantages such as production technology is easy can be used for the serious various aphid mites of murrain, oriental tobacco budworm, fruit tree budworm, corn borer, rice fulgorid, rice leaf roller etc.
The present invention give further instruction in order to illustrate better below by embodiment.
Embodiment 1:
Taking by weighing concentration is 80% methamidophos from crude oil, 100 grams, insert in the there-necked flask that 2000 milliliters of 150 methyl alcohol that restrain are housed, open and stir, acephatemet is dissolved in the methyl alcohol, adds emulsifier, urea 6 gram urea, dimethylbenzene 244 grams that 440 gram concentration are 80% Rogor crude oil, 60 grams again, heat to 70 ℃, stirred 2 hours, precipitation is filtered, promptly.
Embodiment 2:
Take by weighing concentration and be 80% methamidophos from crude oil 215 grams, insert in 2000 milliliters of there-necked flasks that 200 gram methyl alcohol are housed, open to stir, acephatemet is dissolved in the methyl alcohol, add 300 gram concentration again and be 80% Rogor crude oil, the emulsifier of 100 grams, 15 gram urea, toluene 170 grams, heat to 70 ℃, stirred 2.5 hours, precipitation, filter, promptly.
Embodiment 3:
Take by weighing concentration and be 80% methamidophos from crude oil 150 grams, insert in 2000 milliliters the there-necked flask that 180 gram methyl alcohol are housed, open and stir, acephatemet is dissolved in the methyl alcohol, and adding 385 gram concentration again is 80% Rogor crude oil, the emulsifier of 80 grams, 10 gram urea, dimethylbenzene 195 grams.Heat to 70 ℃, stirred 2.5 hours, precipitate, filter, get final product.
