Compatibility of Fungicides with Potent Trichoderma Isolates

Abstract

The sensitivity of biological control agents were tested against fungicides that are used to treat plant diseases. Application of fungicides should not interfere with biological control agents ability to effectively manage disease. Trichoderma is an aggressive coloniser of soil and plant roots that can flourish in a variety of environmental circumstances. It also functions as a natural bioagent to shield plants against infection by soil-borne fungal infections. Evaluation of the various fungicides against five potent Trichoderma isolates in vitro was done in order to determine the compatibility of bioagents with the fungicides was performed at the Department of Plant Pathology, College of Agriculture, JNKVV, Jabalpur. Trichoderma was highly compatible with the following contact, systemic, and combi fungicides: Imbrex (Fluxapyroxad EC), Curzate M8 (Cymoxanil 8%+ Mancozeb 64% WP), Vitavax (Carboxin 37.5% + Thiram 37.5% DS) and Seedkot (Thiram 75% WS), while it proved just moderately compatible with Amistar top (Azoxystrobin 18.2% + Difenoconazole 11.4% SC) and Headline (Pyraclostrobin 20% WG). It showed least compatibility with Nativo (Tebuconazole 50%+ Trifloxystrobin 25% WG), Taqat (Captan 70%+ Hexaconazole 5% WP), Folicur (Tebuconazole 25.9% EC), and Saaf (Carbendazim 12% + Mancozeb 63% WP).
