Problems solved by technology

[0003] 1. The solvent in this preparation is methanol, which has poor storage stability, and usually the decomposition rate is over 20% after heat storage
[0004] 2. Acephate is a slow-acting insecticide with slow insecticidal speed
[0005] 3. The production cost of acephate original drug is high, the effective dosage per mu is large, and the production and use costs are relatively high
[0006] 4. Acephate is a systemic insecticide, and frequent use of a single dose can easily lead to drug resistance and affect its service life
In addition, the insecticide is not effective in killing older larvae
[0007] 5. EC preparations waste solvents, pollute the environment, and do not meet the requirements of the development trend of pesticides
Therefore, although phoxim has a good control effect on rice borer, it has not become a conventional drug for controlling rice borer.

Abstract

A composite insecticide in the form of wettable powder for preventing and eliminating the pests of rice, fruit tree, vegetables, etc is prepared phoxim, acephate, assistant and filler through adsorptive mixing, and pulverizing.

Description

Technical field: [0001] The invention belongs to pesticide compounding and a preparation method thereof, in particular to a compound insecticidal wettable powder prepared from phoxim, acephate, auxiliary agents and fillers through adsorption, mixing and crushing. Background technique [0002] Methamidophos is a conventional pesticide for controlling rice borers, especially rice leaf rollers. Due to its high toxicity, it has been included in the list of banned pesticides, and its use has been banned in many rice producing areas. As a low-toxic substitute product of methamidophos, acephate has increasingly become a routine pesticide for the control of rice leaf roller. The currently commercialized acephate preparation is mainly 30% acephate emulsifiable concentrate. The main disadvantages of this preparation are: [0003] 1. The solvent in the preparation is methanol, and the storage stability is very poor, and the decomposition rate after thermal storage usually reaches mor...
