Blackgram (Vigna mungo L. Hepper) is a vital pulse crop often affected by foliar fungal diseases like Cercospora leaf spot, Anthracnose and Powdery Mildew. A field study was conducted at MARS, UAS Dharwad, during Kharif 2021 to evaluate the efficacy of Fluxapyroxad + Pyraclostrobin (Priaxor 500 SC) against these diseases. The fungicide applied at dosage of 300 and 200 ml/ha significantly reduced disease severity, recording mean disease severity of 15.06 and 15.58 % for Cercospora leaf spot, 15.68 and 16.34 % for Anthracnose and 18.21 and 18.60 % for powdery mildew, with 55-60% reduction over control. The highest yield (9.07 q/ha) and no phytotoxic effects were observed with Priaxor 500 SC @ 300 ml/ha. The dual-action SDHI and QoI chemistry provided both protective and curative benefits. Thus, Priaxor 500 SC @ 200 ml/ha is recommended for effective and sustainable management of foliar diseases of blackgram.
