Abstract
Sorghum [Sorghum bicolor (L.) Moench] belongs to the family Poaceae. In India, sorghum is grown both in kharif and rabi seasons. Sorghum production in the world is affected by different biotic and abiotic factors. Among which sorghum anthracnose caused by Colletotrichum graminicola is considered one of the most important damaging diseases of sorghum. The present investigation was carried out during 2023 and 2024 kharif season at Agriculture Research Station, NAU, Mangrol with aimed to find out a management of anthracnose by using different fungicides either individually or in combination. Different treatments were tested in the field growing highly susceptible dual purpose sorghum cultivar CSV-21. Total seven fungicides Mancozeb 75% @ 0.3%, Carbendazim 12% + Mancozeb 63% wp @ 0.3%, Azoxystrobin 18.2 + Difenoconazole 11.4% w/w SC, Thiophanate methyl 70% WP, Metiram 55% + Pyraclostrobin 5% WG, Propiconazole 25 EC @ 0.1% and Carbendazim 50 WP @ 0.1% and control were tested. The two years pooled data results were revealed that foliar spray of Carbendazim 50% WP @ 0.1% seed treatment showed minimum disease (PDI) 27.67% with maximum 27.02 per cent disease control (PDC) and highest grain yield 3504 kg/ha and dry fodder yield 13511 kg/ha, respectively as compare to other treatments over control.
