Comparative Efficacy of Durofume and other Fumigants against Root-Knot Nematode and Weeds in FCV Tobacco Nurseries*

Studies were conducted to compare the efficacy of Durofume with methyl bromide and ethylene dibromide individually in nurseries and resultant yields by use of seedlings from fumigated beds. Durofume and methyl bromide were highly effective in controlling root knot and weeds in tobacco nurseries. Ethylene dibromide was inferior to both, though having nematicidal and weedicidal action. Though the cost of treatment is high initially, in view of the multiple advantages viz., absolute nematode control, weed control, increased transplants and increase in cured yields by using seedlings from fumigated beds, utility of durofume in nurseries is advocated.
