Bacillus Subtilis
Bacillus subtilis is a beneficial soil bacterium used to naturally control crop diseases. It works by producing antimicrobial compounds that kill harmful fungi and bacteria, triggering plant immune responses, and competing with pathogens for space and nutrients. It also releases enzymes that break down fungal cell walls and helps plant growth by improving nutrient absorption. Farmers use B. subtilis as a seed treatment, soil treatment, and plant spray to combat diseases like root rot, blight, and powdery mildew. It also helps stop spoilage in fruits and vegetables. A safe, environmentally friendly, and sustainable control, B. subtilis is a main tool for limiting crop diseases, reducing the reliance on chemical controls.
