Abstract

An in vitro study was conducted at the Department of Plant Pathology, Dr. Sharadchandra Pawar College of Agriculture, Baramati, during 2024–2025, using Completely Randomized Design (CRD) to assess the compatibility of Trichoderma asperellum with seven fungicides at full and half recommended doses via the poison food technique. Fluxapyroxad 333 g/L FS and Kresoxim-methyl 44.3% SC were found to be highly compatible, allowing over 90% radial growth of T. asperellum at both concentrations. Fosetyl-Al 80% WP showed moderate compatibility (65–75% growth), while Tebuconazole 25.9% EC, Difenoconazole 25% EC, Propiconazole 25% EC and Hexaconazole 5% EC were incompatible, significantly inhibiting fungal growth. The findings indicate that Fluxapyroxad and Kresoxim-methyl can be safely integrated with T. asperellum in disease management, whereas caution is needed with Fosetyl-Al and the remaining fungicides should be avoided. This study supports the selection of compatible chemical partners in integrated plant disease management programs involving biological control agents.
