Management of Cercospora Leaf Spot [Cercospora canescens Ellis and Martin] of Mothbean [Vigna aconitifolia (Jacq.) Marechal] through Fungicides

Background: Cercospora leaf spot of mothbean caused by canescens Ellis and Martin is one the most important fungal diseases causing damage to crop. C. causes losses yield in major Mothbean growing areas Rajasthan. Its affects foliation severe infection damaged entire crop that lead loss up 50-70%. In this, Check efficacy new molecules available market should be analyzed with this disease. Methods: Nine fungicides were tested at four concentrations (50, 100, 150 200 ppm) under vitro conditions CRD design against also field conditions. The experiment was conducted Research Farm College Agriculture, SKRAU, Bikaner, during Kharif 2019 RBD application foliar spray nine different disease mothbean. Result: Among these molecule tested, trifloxystrobin 25% + tebuconazole 50% WG carbendazim 12% mancozeb 63% WP highly effective maximum inhibition mycelial growth (100.00%) ppm concentrations. results vivo studies revealed spraying 0.15% helped manage successfully reduced intensity (15.51%) control (72.71%) recorded highest (8.10 q ha-1) as appropriate time.
