Product Overview:

Avermectin B1a is a naturally derived macrocyclic lactone compound obtained through the fermentation of Streptomyces avermitilis. It is the major active component of the Avermectin B1 mixture, often comprising over 90% of the total content. Known for its high potency at low doses, Avermectin B1a exhibits powerful insecticidal and acaricidal properties, making it highly effective against a variety of mites and insect pests.

It works primarily by disrupting the nervous system of target pests, causing paralysis and death. Avermectin B1a is widely used in agriculture, horticulture, and animal health, and is suitable for integrated pest management (IPM) programs due to its natural origin and low environmental persistence.
