The trial was conducted to test the efficacy of pre-harvest spray of fungicides and bioagents on post-harvest storage diseases of onion variety Agrifound Light Red during rabi, 2011-12 and 2012-13 at Regional Research Station (RRS), National Horticultural Research and Development Foundation (NHRDF), Karnal, Haryana. The efficacy of fungicides namely carbendazim + mancozeb, metalaxyl, iprodione, propineb and bio-agents like Trichoderma viride, T. harzianum and Pseudomonas fluorescens were tested as pre-harvest foliar spray against post-harvest diseases of onion. The pooled data of storage trials conducted for the period from May to September for 120 days revealed that maximum disease reduction index of black mold was recorded with pre-harvest spray of Metalaxyl@ 0.1% (56.25%) followed by Carbendazin + Mancozeb @ 0.2% (49.07%) as compared to untreated control. The study revealed that pre-harvest spray of systemic fungicide alone and combination of systemic and contact fungicide were effective in keeping the low incidence of black mold (Aspergillus niger) in Karnal region of Haryana.
