Abstract:
Among many fungal diseases causing threat to soybean production, charcoal rot caused by Macrophomina phaseolina (Tassi) Goid. is a most threatening soil borne fungal pathogen. Fungal, bacterial and endophyte bioagents were evaluated against M. phaseolina by using dual culture technique. Among the bioagents tested, IOF isolate Trichoderma harzianum from UAS Dharwad recorded maximum mycelial inhibition (82.35 %) which was significantly superior over rest of the bioagents. Among contact, systemic and combi product fungicides tested Tebuconazole and, Trifloxystrobin 13.7 % + Penflufen 13.7% (Evergol) and Metalaxyl 4 % + Mancozeb 64 % (Ridomil gold) showed maximum mycelial inhibition. The in vitro evaluation of bioagents and fungicides compatibility tests were conducted. From studies confirmed that T. harzianum (IOF, Dharwad) was more effective compared to other bioagents. So T. harzianum (IOF, Dharwad) was used in compatibility studies with all the 14 fungicides. Results revealed that T. harzianum was more compatible with Trifloxystrobin 13.7% + Penflufen 13.7% (Evergol) (81.20%) followed by Metalaxyl 4 % + Mancozeb 64 % (Ridomil gold) (73.00 %) and mancozeb (71.80%). Least compatibility was observed in Carbendazim (12.46%).
