A newly discovered bacterium called Streptomyces luomodiensis SCA4-21 offers a natural solution to banana Fusarium wilt, a serious disease that destroys banana crops globally. When applied to banana plants, this beneficial bacterium reduced disease occurrence by 59% while also promoting healthier plant growth. The bacterium works by producing antifungal compounds that kill the disease-causing fungus and by enriching the soil with other helpful microorganisms that protect the plant.
