Embodiment Construction

[0008] Get the former drug emamectin benzoate 0.1%, dissolve in 5% solvent DMF, then add the mixture 10 of cyclic phenol polyoxyethylene ether dodecylbenzenesulfonate=8+2 %, then add 20% of the original drug Dimehypo and 64.9% of the water after metering the metering tank and throw it into the reaction pot to stir. After dissolving evenly in 60 minutes, take a sample and analyze it to meet the technical indicators of the present invention: methylamino A Vermectin benzoate% (m / m) ≥ 0.1; Dimehypo% (m / m) ≥ 20; PH value range 5.5-7.5; transparent temperature range (°C) 0-50; emulsion stability is qualified; Long-lasting foaming (1minrd thickness) (ml) ≤ 25; low temperature and heat storage stability are qualified, and then pumped into the settling tank, high-level tank, and filtered through a filter, it becomes a packable product.

[0009] Field drug efficacy tests prove that the present invention (field drug efficacy test report is attached) has the characteristics of fast knockd...

Abstract

The invention relates to methylamino avermectin benzoate*dimehypo micro-emulsion, which is formed by adding a mixture of alkylphenol polyethenoxy ether and dodecylbenzene sulfonic acid, solvent DMF and water into a technical product of methylamino avermectin benzoate, a technical product of *dimehypo. The weight proportion of the phenol polyethemoxy ether and the twelve-cyclo benzene sulfonate is 8:2. Field drug efficacy experiments prove that the drug can knock down rice stem borers quickly, the efficacy is over 90 percent in 20 days after the application of the drug, the consumption is low, the chemical injury does not exist, the production cost of cotton can be reduced, and the benefit can be increased.

Description

technical field [0001] The invention relates to a pesticide for preventing and controlling rice pests, in particular to a kind of emamectin benzoate · insecticidal double microemulsion pesticide for preventing and controlling rice borer. Background technique [0002] In recent years, rice stem borer pests have occurred seriously, and the rice stem borer has produced varying degrees of resistance to the control effects of some pesticides. The amount and frequency of pesticides used by farmers to control stem borer have increased year by year, which has greatly improved farmers. The cost of production is high, and farmers are in urgent need of a medicament that can effectively prevent and control the pest of Chilo suppressalis. Contents of the invention [0003] The object of the present invention is to provide a kind of emamectin benzoate·insecticidal double microemulsion for above-mentioned drawback. It is characterized in that the drug is made by dissolving 0.1%-5.0% of ...
