Abstract:

Systemic resistance in plants can be induced through biotic or abiotic plant defense inducers. Efficacy of plant defense activators was tested against Albugo candida causing white rust on mustard cv. DRMRIJ-31 under artificial epiphytotic conditions during two consecutive cropping season. The maximum reduction of the size of pustules was found in Metalaxyl at 0.3 % was 56.61 % and minimum reduction over the check was recorded in check followed by ZnSO4 at 0.50 % was 15.27 %. In non-conventional chemicals maximum reduction of size of pustules over the check was observed in salicylic acid at 0.25 % was 45.99 % followed by CaSO4 at 1.00 % was 38.98 %. The significant minimum number of pustules was observed in Metalaxyl at 0.2% was 1.73 pustules/25 mm2 area in rabi season (Table 3). Among non-conventional chemicals salicylic acid at 0.25% was found better over all the treatments and zinc sulphate at 0.50 % was recorded minimum reduction of the disease over the check. Among the bio control agents, both Trichoderma viride at 1.00 % and Pseudomonas fluorescens at 1.00 % were found significantly better over the check. The per cent disease index in all the treatments, Metalaxyl 0.3% found superior with 48.69 per cent disease reduction over the check. Among non-conventional chemicals salicylic acid at 0.25% was found best with 38.41 per cent reduction over the check followed by calcium sulphate at 1.00 % showed disease index (29.91 %), Borax at 0.50 % (23.93 %) and potassium sulphate at 1.00 % (18.88 %).
