Effect of pre-harvest fungicidal spray on the control of storage diseases of onion.

Studies were conducted at the Regional Research Station, Nasik, India, during 1993-94 and 1994-95 to investigate the control of basal rot (Fusarium oxysporum f.sp. cepae), bacterial rot (Pseudomonas spp.), black mould (Aspergillus niger) and blue mould (Penicillium spp.) which cause economic losses during the storage of onions. Treatments consisted of 3 sprays of 0.1% carbendazim, 0.25% mancozeb, 0.2% pausamycin, 0.3% copper oxychloride, 0.1% klorocin or 0.2% difolatan [captafol] at 30, 20 and 10 days before harvest, the control received no treatments. After 5 months storage the lowest loss of yield due to decay (24.88%) was obtained with 0.1% carbendazim applied at 750 g/ha.
