Abstract : The growing environmental and health issues due to excessive use of chemical pesticides have increased the need for environmentally friendly alternatives in agriculture. Integrated Pest Management (IPM) offers a green solution by combining biological, cultural, and chemical approaches to minimize pest damage without impacting beneficial organisms. In biological alternatives, biopesticides have become widely popular because they are specific, environmentally benign, and less toxic compared to traditional pesticides. Trichoderma species, particularly Trichoderma harzianum, are widely recognized for their applications in plant disease management, plant growth promotion, and soil health improvement. This study investigates bulk cultivation of T. harzianum on different grains to determine optimal substrate materials and develop a talc-based biopesticide. Findings showed that maize and mixed grains supported maximum growth of the fungus, while rice and wheat were suboptimal. The developed product exhibited maximum viability and shelf-life stability, validating its field efficacy in green agriculture. Statistical analysis confirmed uniform growth patterns on substrates. The study indicates the potential of T. harzianum as a very effective and eco-friendly biocontrol agent, a good substitute for chemical pesticides, and a means of promoting environmentally friendly crop management practices.

Keywords : Integrated Pest Management. Biopesticide, Trichoderma Harzianum, Sustainable Agriculture, Talc-Based Formulation.
