Effect of maleic hydrazide alone and in combination with fungicides, on postharvest losses in storage of rainy-season onion.

ABSTRACT :

 

High losses occurred of stored rainy-season onions in India due to sprouting and decay. It was shown that the use of maleic hydrazide reduced losses due to sprouting. However, at higher doses decay increased. An experiment was conducted at the Associated Agricultural Development Foundations research stations at Karnal (Haryana) and Nasik (Maharashtra) to study the effects of maleic hydrazide (MH) alone at 1500, 2000 and 2500 p.p.m. and in combination with captafol at 0.2% and carbendazim at 0.1%. MH at 2500 p.p.m. gave significantly lower sprouting and total loss both at Karnal and Nasik. Although there were no significant differences in decay at either location, application of MH in combination with fungicides, i.e. MH at 2000 p.p.m. + carbendazim at 0.1%, resulted in less sprouting and decay at Nasik. However, at Karnal, no such trend in losses due to decay (which may be due to bacterial infection against which fungicides have no effect) was observed.
