Abstract

The present invention discloses an insecticidal aqueous emulsion containing abamectin. Its composition contains (by wt%) abamectin 0.1-5%, emulsifier 5-25%, antifreezing agent 1-5%, defoaming agent 0.05-0.2%, solvent 3-35%, thickening agent 0.5-1% and the rest is water. It can be extensively used for killing antagonistical pests of cabbage moth, leaf miner and red mite, etc. on the vegetables, tangerine and cotton, etc.

Description

technical field [0001] The invention relates to an insecticidal aqueous emulsion containing abamectin, in particular to an abamectin-containing insecticidal aqueous emulsion for plant protection. Background technique [0002] There are many types of insecticides used to protect plants, and emulsifiable concentrates and wettable powders are generally used. It is well known that emulsifiable concentrate contains a large amount of organic solvent, which is easy to volatilize and catch fire, poisonous to human body and plants, pollutes the environment, and is inconvenient to transport; wettable powder has a lot of dust in production and use, pollutes the environment and affects the health of operators. Contents of the invention [0003] The invention overcomes the disadvantages in the prior art and provides a safe and environment-friendly insecticidal water emulsion containing abamectin. [0004] In order to solve the problems of the above-mentioned technologies, the present ...
