Greengram cultivation is severely constrained by destructive foliar diseases, often causing yield losses of up to 60%. To address this challenge, a field trial was conducted during kharif 2021 at UAS, Dharwad to evaluate the efficacy of Fluxapyroxad 167 g/L + Pyraclostrobin 333 g/L 500 SC (Priaxor® 500 SC) against the major fungal foliar diseases of greengram (Vigna radiata L. Wilczek). Priaxor 500 SC effectively reduced Cercospora leaf spot, Anthracnose and Powdery mildew incidence. Application of this combi fungicide at 300 ml/ha recorded the lowest mean PDI values (15.84, 13.61 and 12.71) with corresponding yield improvement of 60.97 per cent over control which was closely followed by 200 ml/ha, which was statistically on par with higher dosage. No phytotoxic effects were observed even at higher doses. The superior efficacy is attributed to the complementary action of fluxapyroxad (SDHI) and pyraclostrobin (QoI), providing both preventive and curative protection. Priaxor 500 SC @ 200 ml/ha emerged as a highly effective, economically viable and safe option for managing foliar fungal diseases and enhancing productivity in greengram.
