With purity ranging from 98% to 100%, it effectively controls pests like caterpillars and other larvae on fruit trees, vegetables, herbs, and flowers. This naturally occurring bacterium produces proteins toxic to specific insect pests, without harming beneficial insects or plants. Processed through fermentation, Bt requires specialized bioreactors for optimal production. Available in various packaging options, including powders or liquid formulations, its widely used in organic farming, horticulture, and crop protection.
