Description

technical field

[0001] The invention relates to the production field of biological pesticide products, in particular to an extraction process of abamectin. Background technique

[0002] With the improvement of people's living standards and the call for green food, biopesticides are favored in the current pesticide market, and avermectin is the most popular biopesticide product with great development potential in the current biopesticide market.

[0003] As a new type of biopesticide, abamectin has the following unique advantages: wide insecticidal spectrum, strong insecticidal activity against various insects, mites and animal parasites; Cross-resistance and long-lasting effect; easy to degrade in soil and water, no accumulation and persistent residue in organisms, no pollution to the environment, and no pollution. Therefore, Abamectin and its derivatives occupy an increasing share in the pesticide and veterinary drug market, and their development prospects are very optimis...
