PureAg Biologic Army is a unique combination of predatory bacteria and parasitic fungi. Bacillus thuringiensis is a natural occurring, soil-borne bacteria used for natural insect control. It consists of a spore, which gives it persistence, and a protein crystal within the spore, which is toxic. When the bacteria is consumed by certain insects, the toxic crystal is released in the insects highly alkaline gut, blocking the system which protects the pest’s digestive system. The stomach is penetrated, and the insect dies by poisoning from the stomach contents and the spores themselves. This same mechanism makes BT harmless to birds, fish and mammals whose acidic gut conditions negate the bacteria’s effect.
