Assessment of different fungicides against rust (Uromyces fabae de Bary) disease of field pea (Pisum sativum L.)

Abstract

The present study was conducted during Rabi season of year 2017-18 at the experimental field of JNKVV, Jabalpur (M.P.) for assessment of different fungicides in controlling rust disease of field pea. Seven treatments including control with three replications were taken up by using RBD. Treatments of foliar spray of propiconazole (Tilt 25% EC) @ 0.1% (T1), tebuconazole (Folicure 25.9% EC) @ 0.17% (T2), difenoconazole (Score 25% EC) @ 0.06% (T3), hexaconazole (Contaf plus 5% SC) @ 0.2% (T4), azoxystrobin (Amistar 23% SC) @ 0.1% (T5), carbendazim + mancozeb (Saaf 75% WP) @ 0.2% (T6) and control (Spray of plain water)- T7, were applied at the first initiation of disease symptoms and second at 15 days after the first spray. The data were recorded at 15 and 30 days after the spray. Results showed that the per cent disease intensity (PDI) was significantly low (11.40 and 14.96%) in Propiconazole 25% (EC), followed by Difenoconazole 25% (EC) with 14.66 and 16.09 per cent, respectively. The highest seed yield was recorded in Propiconazole 25% (EC) sprayed plot 19.61 q/ha, followed by Difenoconazole 25% (EC) with 19.40 q/ha, respectively as compared to control which recorded maximum per cent disease intensity (28.74 and 39.85%) and lowest yield 13.75 q/ha.
