Problems solved by technology

At present, the market demand for low-toxicity, high-efficiency and environment-friendly pesticides is relatively large, but the supply is small.
[0005] For a long time, all liquid pesticide technical materials and solid technical pharmaceuticals with considerable solubility in organic solvents, whether they are insecticides, acaricides, fungicides or herbicides, are mostly in the form of emulsifiable concentrates. Use, pesticide emulsifiable concentrate has always been an important dosage form of pesticide preparations, but because the emulsifiable concentrate contains a large amount of flammable organic solvents, it has strict requirements on production, storage, transportation, and use. Phytotoxicity
Especially in the long-term use process, a large amount of organic solvents volatilize into the atmosphere, causing serious pollution to the environment, all these problems have caused widespread concern

Abstract

An aqueous emulsion of methylamino abamectin benzoate is proportionally prepared from methylamino abamectin benzoate, solvent, emulsifier, thickening agent, anti-freezing agent, defoaming agent and water through preparing oil phase, preparing water phase and mixing while shearing.

Description

Technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to an emamectin benzoic acid salt water emulsion for preventing and controlling vegetable beet armyworm, Spodoptera litura, Plutella xylostella, Pieris rapae and other crop pests and a preparation method thereof. Background technique [0002] In recent years, global pesticide policies have undergone great changes. In particular, developed countries have very strict restrictions on the use of highly toxic and high-residue pesticides. Especially after the national ban on the use of highly toxic pesticides in agriculture on January 1, 2007, the domestic market The demand for high-efficiency, low-toxicity, and low-residue environmentally friendly pesticides will increase, and high-toxic pesticide varieties will be ruthlessly eliminated under the effect of the prohibition order. Restricting and further banning highly toxic pesticides is the trend of social development and the ne...
