Context: The Punjab Agricultural University (PAU) has developed a biocontrol agent, Trichoderma asperellum, to manage foot rot disease in Basmati rice crops.
About Foot Rot Disease: It is a fungal disease affecting Basmati rice crops, primarily at the seedling stage. Caused by Fusarium verticillioides, a soil-seed borne pathogen. Spreads through the plant root, leading to stem base colonization. Symptoms include pale yellowing, elongation, drying, and eventual death of seedlings. Current treatments involve chemical fungicides like Sprint 75 WS (carbendazim + mancozeb), harmful to soil and consumers.
Trichoderma asperellum: Biocontrol agent offering a non-chemical alternative, aiding disease management while minimizing environmental harm.
