Pearl millet (Pennisetum glaucum L.) is a versatile cereal crop grown for food, feed and forages. It is affected by several diseases. Among them the bajra blast caused by Pyricularia grisea (Cooke) Sacc. has become a serious threat to pearl millet grain and fodder production from last 8-10 years. In the present study, efficacy of nine fungicides was evaluated in vitro at three different concentrations (1000, 1500 and 2000 ppm) at Department of Plant Pathology, College of Agriculture, Agricultural University, Jodhpur in 2020-21. Among all, tricyclazole, carbendazim 12% + mancozeb 63% and tebuconazole 50% + trifloxystrobin 25% at all the concentrations completely inhibited the mycelial growth (100%) over control and were found significantly superior over rest of the treatments. Fungicide carbendazim was the second best with (99,100 and 100% inhibition) at 1000, 1500 and 2000 ppm concentrations, respectively followed by tricyclozole18%+mancozeb 62% with (95, 97 and 100% inhibition) at 1000, 1500 and 2000 ppm concentrations, respectively. While chlorothalonil fungicide was the least effective in inhibiting the mycelial growth (46, 48 and 51%) at 1000, 1500 and 2000 ppm concentrations, respectively.
