Abstract
The present invention relates to a micro-emulsion for preventing and curing various mites of crops of fruit, vegetable and cotton, etc., pests, American otitid, cotton bollworm and pear psyllid, etc.. It is made up by using (wt%) 0.01-0.05% of avermection or ivermectin, 1.0-4.0% of high-effective cypermethrin, 4-20% of emulsifying agent, 0.1-2.0% of synergist, 5-28% of cosolvent, 0.1-1.0% of stabilizing agent and a proper quantity of deionized water through a certain preparation process. It can be made into the high-effective pesticide, miticide and nematicide, and features high-efficiency, low toxicity and less dosage.
Description
The present invention relates to a kind of A Wei, Yi Wei micro emulsion insecticide, miticide, nematocide of preventing and treating insects such as the various insects of crops, mite class, tame carcass interior lines worm, it is a kind of by A Wei or the former powder of Yi Wei (or its syrup) and efficient chlorine cyanogen, emulsifier, synergist, cosolvent, stabilizing agent, deionized water etc. to say so in more detail, with the PIT emulsifying process process efficiently, the water base microemulsion as insecticide-miticide of low toxicity.
At present, the insect such as various insects, mite class that is used for crops such as fruit tree, wheat, paddy rice, peanut, cotton, vegetables is Avermectin or ivermectin cream preparation and high chloro milk oil more effectively, control efficiency is good, but cost is too high, drift is big during use, permeability is relatively poor, and residual effect is shorter.
The objective of the invention is to overcome the deficiency of above-mentioned existing procucts, and provide that the former dose of a kind of usefulness is few, with low cost, drift is little, permeability is strong during dispenser microemulsion as insecticide-miticide.
Purpose of the present invention can realize by following measure:
In reactor, add successively:
(a) weight concentration is Avermectin or the ivermectin of 0.01-0.05%;
(b) weight concentration is the beta-cypermethrin of 1.0-4.0%;
(c) weight concentration is the emulsifier of 4-20%;
(d) weight concentration is the synergist of 0.1-2.0%;
(e) weight concentration is the cosolvent of 5-28%;
(f) weight concentration is the stabilizing agent of 0.1-1.0%;
The rest is deionized water.
Purpose of the present invention can also realize by following measure:
Adding a certain amount of cosolvent in A Wei or the former powder of Yi Wei or syrup (active constituent content 3-7%) and the high chlorine, be heated to 80-85 ℃, in (the rotating speed 200-400 rev/min) process of stirring, add emulsifier, temperature remains on 85-90 ℃, add hot deionized water (temperature 95-98 ℃) then, stirred 30-60 minute, add surplus cosolvent, synergist and stabilizing agent again, emulsion is converted into clear solution automatically in cooling procedure then, be chilled to about 30 ℃, leave standstill then, filter, pack and promptly get agricultural chemicals of the present invention.

Avermectin (Avermectin) is the macrolides farm antibiotics that is produced by streptomycete, and its main active is B
1Component; Ivermectin (Ivermectin) is two hydrogenation Avermectin, and stability is better, and insecticidal activity and Avermectin are suitable.
The molecular structure of the beta-cypermethrin that uses among the present invention (Alphamethrin) is:
Cypermethrin can generate dichloro chrysanthemum acyl chlorides with dichlor chrysanthemic acid after chloride, promptly get cypermethrin with ether aldehyde and Cymag reaction then, and again that it is suitable, trans isomer separation obtains efficient (cis) cypermethrin.
Used emulsifier is to be formed according to 70/10/20 ratio is composite by anion surfactant, cationic surfactant and deionized water among the present invention.
Used cosolvent is made up of one-components such as higher aliphatic, PVP, ether, polyalcohols among the present invention, has height and oozes, helps emulsification function and can antifreeze, froth breaking, increases the stability of system simultaneously.
Used synergist is ten thousand spirits (Methomyl), granville carbosulfan etc. among the present invention.
Used stabilizing agent is ultra-violet absorber, DMF etc. among the present invention.
The present invention give further instruction in order to illustrate better below by embodiment:
