Abstract:
To find out most suitable newer molecule fungitoxicants for minimizing Alternariablight disease incidence of oilseed Brassica crop getting maximum yield a trial was carried out during Rabi 2019-20 in field condition at Tirhut College of Agriculture, Dholi, Muzaffarpur farm in RBD with three replications and eight treatments. Six different fungitoxicants namely, Carbendazim 50WP, Hexaconazole 5EC, Mancozeb 75WP, Propiconazole 25EC, Trifloxystrobin 50WG and Carbendazim12%+ Mancozeb 63% were evaluated for their efficacies on pathogen. Data on the yield measurements under different treatments shows that all the treated plots resulted in better crop and less disease incidence than the control plots. The plots given seed treatment with Carbendazim 50WP @2g/kg seed and foliar sprays of Trifloxystrobin 50WG @ 1g/l of water were found to be superior on all the other treatments. Least PDI (20.5%), maximum 1000 seed weight (4.1g), highest yield (1430 kg/ha), maximum yield increased over control (591.7kg/ha) and highest CB ratio of 1.71 was recorded from this treatment. This treatment was statistically at par with seed treatment with Carbendazim50WP @ 2g/kg seed and foliar spray with Propiconazole 25EC @1ml/l of water where 27.8% PDI, 3.8g per 1000 seed weight, 1343.3 kg/ha yield, 505.0 kg/ha increased yield over control and 1.60 CB ratio was recorded.
