Abstract
The present investigation was conducted during Rabi 2024 at the Organic Research Farm, Bundelkhand University, Jhansi, to evaluate the efficacy of seed bio-priming with chemicals and biocontrol agents against white rust of mustard caused by Albugo candida. The experiment, laid out in a Randomised Block Design with nine treatments and three replications, assessed disease incidence at 30, 45 and 60 DAS. Among all treatments, Mancozeb @ 3 kg-1 seed showed the lowest mean disease incidence (16.80%), followed by Carbendazim (17.80%). Biocontrol agents like Trichoderma harzianum also provided effective disease suppression (19.04%), while botanical extracts showed moderate control. Overall, seed treatment with fungicides and bioagents significantly reduced disease incidence compared to the untreated control, highlighting its importance in integrated disease management strategies for sustainable mustard production.
