Cost benefit ratio of bio-control agents, botanicals and fungicide in the management of white rot of onion caused by Sclerotium rolfsii Sacc. in Manipur
The research investigation was undertaken to evaluate the economics of the management of white rot of onion by Trichoderma harzianum, Trichoderma viride, garlic (Allium sativum L.), turmeric (Cucurma longa L.), sweet flag (Acorus calamus L.) and Carbendazim (50% WP). Carbendazim recorded highest gross return followed by T. harzianum and T. viride respectively. Carbendazim also recorded highest net return followed by T. harzianum and garlic respectively. Among the treatments, Carbendazim gave the highest net return cost benefit ratio of 1:3.25. Garlic extract gave cost benefit ratio of 1:2.96. T. harzianum gave cost benefit ratio of 1:2.89.
