Abstract

Influence of MH and carbendazim application in preventing loss of onion bulbs during storage was assessed in two varieties. Individual treatment of 2,000 ppm MH reduced the percentage of rotting, fungal infection and sprouting to a greater extent in variety 'N-53'. The preharvest treatment appeared more effective than the postharvest in this variety. In case of 'Local White' also a similar trend was observed but the response obtained in general was not promising. Preharvest treatment with carbendazim significantly reduced the rotting and fungal infection in both the varieties during storage. However a combined application of carbendazim and MH (1,000 ppm and 2,000 ppm, respectively) exhibited better results as compared to the individual treatments in both the varieties.
