In-vitro Evaluation of Fungicides and Botanicals against Uromyces ciceris arietini Inciting Chickpea Rust Disease

Chickpea, commonly known as gram is one of the important pulse crops in India. The crop faces numerous disease attacks, resulting in losses to both quality and quantity. Among the diseases, rust caused by Uromyces ciceris arietinum, is a sporadic disease of chickpea. Considering the notoriority of disease A study was conducted at department of plant Pathology and Agril Microbiology, PGI MPKV, Rahuri during 2021-22 which aimed to assess the efficacy of fungicides against the pathogen causing rust disease under in vitro conditions. Among five fungicides, Tebuconazole 50% + Trifloxystrobin 25% w/w WG and Azoxystrobin 18.2% + Difenoconazole 11.4% w/w SC were found cent per cent effective against U. ciceris arietini, which completely inhibited uredospore germination at all three concentrations, viz. 50 ppm, 100 ppm, 500 ppm. However, Propiconazole 25% EC, Tebuconazole 25% EC and Hexaconazole 5% SC were found cent per cent effective against test pathogen only at 500 ppm. Among botanicals, Azadirachtin and Pongamia oil showed effective treatments to some extent. Maximum uredospore germination (63%) was recorded in control (Tap water).
