Description To ensure seed quality, peanut seeds received for export by the Plant Quarantine Unit of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) were subjected to phosphine and methyl bromide fumigation. Effective control of eggs, larvae, and adults of Caryedon serratus Olivier was achieved with methyl bromide vacuum fumigation (16 g/m3 for 4 h exposure). Under normal atmospheric pressure (NAP), phosphine fumigation @ 0.5,1.0, and 2.0 g a.I./m3 for 24, and also with 0.25 g a.l. for 72 h gave effective control of eggs and larvae. Ph~phlne (1.0 g a.l./40 kg burlap bag) with bruchld Infested pods for 120 h resulted in 100% larval and 93% adult mortality. Both the fumigants did not impair the viability of peanut seeds. A dosage of 16 g/m3 of methyl bromide for 4 h under vacuum or 0.25 g a.l./m3 of phosphine for 72 h under NAP or placing 1.0 g a.l. of ph~phlne in dry pods stored in 40 kg burlap bag covered with polythene sheets for 120 h can satisfy the seed health requirements.
