Bacillus subtilis Biofungicide for Potato Disease Management in West Bengal
Potato is an important commercial winter-season crop in West Bengal, particularly across Hooghly, Purba Bardhaman, Paschim Bardhaman, Bankura, Paschim Medinipur and surrounding agricultural regions.
Commercial potato production requires healthy seed tubers, balanced fertilization, suitable irrigation, good soil drainage and effective management of soil-borne pathogens.
Potato crops may be affected by fungal pathogens such as Rhizoctonia solani and certain Fusarium species. These organisms can cause diseases affecting underground stems, roots and developing tubers.
Rhizoctonia solani is responsible for potato black scurf and stem canker. Black scurf produces dark fungal structures on the tuber surface, while stem canker may damage underground stems and interfere with normal crop establishment.
Bacillus subtilis is a beneficial spore-forming bacterium widely studied for plant growth-promoting activity and biological antagonism against selected fungal pathogens.
Peak Laboratories manufactures Bacillus subtilis microbial agricultural products in liquid and powder formulations for potato growers, agricultural distributors, wholesalers and bulk buyers across West Bengal and India.
Role of Bacillus subtilis in Potato Root Health and Biological Fungal Suppression
Bacillus subtilis is a Gram-positive, spore-forming bacterium capable of surviving under a range of environmental conditions. Its spores can contribute to formulation stability when products are manufactured and stored appropriately.
Selected strains produce antimicrobial lipopeptides such as surfactin, iturin-family compounds and fengycin-family compounds. These metabolites may contribute to antagonistic activity against susceptible fungal organisms.
Some strains can form biofilms and colonize root-associated environments, allowing beneficial bacteria to interact with plant roots and other microorganisms.
Research has investigated selected Bacillus subtilis strains for suppression of Rhizoctonia solani, the pathogen associated with potato black scurf and stem canker.
Certain strains have also been studied for activity against other fungal pathogens, although the results vary with the organism, bacterial strain and environmental conditions.
Bacillus subtilis for Potato Seed Tuber, Soil and Rhizosphere Management
Healthy seed tubers are essential for successful potato cultivation. Infected planting material can introduce pathogens into agricultural fields and contribute to early disease development.
Where supported by applicable product-label directions, suitable Bacillus subtilis formulations may be incorporated into seed-tuber treatment or planting-stage biological management programs.
Soil application may introduce beneficial bacterial cells or spores into the potato root-zone environment, where they can interact with developing roots and soil microorganisms.
During crop establishment, suitable root-zone conditions may encourage beneficial microbial activity. Soil moisture, temperature, organic matter, pH and microbial competition can influence bacterial survival and colonization.
