Bacillus subtilis is a spore forming bacterium which, when applied to the seeds or plants, it colonizes the developing root system of the plants. The bacterium competes with and thereby suppresses fungal disease such as Rhizoctonia, Fusarium, Aspergillus, and others.
Bacillus subtilis continue to live on the root system and provide protection throughout the growing season. Therefore, even if treated seeds are stored for prolonged periods, the bacteria stay alive, and then grow and multiply after the seeds are planted.
