A naturally occurring bacterium called Cystobacter fuscus shows great promise as a biological control agent against a serious fungal disease that damages cotton plants. When formulated as a solid product and applied to soil, this microorganism was able to prevent disease in over 70% of cotton plants tested in greenhouse experiments. The bacteria work by attacking and breaking down the fungal pathogen while also promoting healthier plant growth, offering farmers an environmentally friendly alternative to chemical fungicides.
