Mustard (Brassica juncea L. Czern. and Coss) Is an important oilseed crop grown in India. White rust of mustard caused by Albugo candida (Pers.) Kuntze, is one of the major diseases of mustard causing significant yield loss. It’s always better not to use same molecules for the management for long periods to avoid the probable development of resistance by the pathogens to the old fungicides. Accordingly, the current investigations were carried out to assess the efficacy of new molecules and bioagents both under lab and field conditions. The results of these investigations showed the efficacy of two fungicides Azoxystrobin 18.2% + Difenconazole 11.4% SC at 0.1 per cent concentration and Metalaxyl 8% + Mancozeb 64% at 0.2 per cent concentration in reducing white rust disease incidence with high returns (good quality pod and seed yield). It is suggested that these can be tested further under large-scale trials.
