Title	A laboratory study on the minimum dosage requirements for effective methyl bromide fumigation of food commodities.

Description	Fumigation trials were carried out to find the minimum effective dosages of methyl bromide required for about 37 stored products at 27 plus or minus 2 deg C and 40-85% RH, with adults of Tribolium castaneum (Hbst.) and third-instar larvae of Trogoderma granarium Everts as the test insects. The fumigant concentrations were noted after 0.5, 2, 4, 7 and 24 h, concentration-time curves were drawn for each commodity and integrated CT products were determined. For treatment for a period of 24 h, the stored grain (except rice), pulses (except cowpea [Vigna unguiculata]), oilseeds, spices, rice bran and poultry feed required a minimum dosage of 16 mg/litre; milled cereals required 24-32 mg/litre; for pulse cakes products, oil cakes and fish meal, the effective range was 32-64 mg/litre. Fish meal and greengram [Vigna] splits were the most sorptive commodities tested; the CT products were 112 mg.h/litre for the former when exposed to 48 mg methyl bromide/litre and 106 mg.h/litre for the latter at 64 mg/litre. Tamarind pulp was the least sorptive commodity and required only 8 mg/litre to yield the required CT product.
