Harnessing Trichoderma asperellum: Tri-Trophic Interactions for Enhanced Black Gram Growth and Root Rot Resilience.

Root rot caused by Macrophomina phaseolina, a common soil-borne disease in black gram, is managed with chemical fungicides, leading to toxicity and degradation of beneficial soil microbes. Existing bioagents, like talc formulation, cause leaching, clogging, and reduced productivity. The development of liquid bio-formulation via drip irrigation is crucial to mitigate biotic stress and maximize yield.
