How is Bacillus subtilis used in agriculture?

Bacillus subtilis is recognized for its role as a beneficial bacterium in agriculture, particularly as a seed treatment pesticide. This bacterium has the ability to enhance plant growth and provide protection against various pathogens. When formulated as a seed treatment, Bacillus subtilis can colonize the seed surface and promote early root development while simultaneously suppressing seed-borne diseases. This enhances seedling vigor and helps establish healthier plants.

The benefits of using Bacillus subtilis include its natural origin, effectiveness against soil-borne pathogens, and ability to improve soil health without the negative impacts associated with synthetic pesticides. This formulation can lead to improved crop yield and reduced dependence on chemical alternatives.

In contrast, while Bacillus subtilis can serve in other agricultural applications, such as soil amendments or even foliar sprays in specific contexts, the primary and most impactful use relevant to seed treatment practices is in its role as a seed treatment pesticide.
