Abstract

Experiment was conducted to study the effect of plant defense activators on white rust of Indian mustard cultivar RH-
749 under artificial epiphytotic conditions. The size of pustule of white rust was recorded minimum in Metalaxyl 0.3%
(0.32 mm) followed by Metalaxyl 0.2% (0.33 mm) during 2015-16, although, the maximum size of pustules were observed
in check was 6.55 mm followed by zinc sulphate at 0.50% (5.88 mm) during 2016-17. Among the abiotic chemicals, salicylic
acid was recorded significantly better among all the treatments. The number of pustules were recorded maximum in check
was 7.47 and 7.53 followed by zinc sulphate at 0.50 % was 7.1 and 7.3 during 2015-16 and 2016-17, respectively. Salicylic
acid 0.25% reduces 31.5% white rust disease over the control followed by calcium sulphate at 1.0% which reduces
disease 24.0%. Zinc sulphate at 0.50% was found least effective abiotic chemical which reduce 6.1% disease
