Description Phosphine scores over other fumigants on many aspects including ease in application, low cost, less residue problem and least effects on treated food commodities. It is the major fumigant currently used for the protection of stored' products in- India and elsewhere. It has certain unique features in its toxic action against insects. Large variations are observed in the susceptibility not only between the developmental stages of the same species but also between the age groups of the same life stage. Longer exposure period is essential for its effective ness. Insects are narcotized at higher phosphine concentrations. The toxicity is not enhanced by combining with any other fumigant. Carbon dioxide, although potentiates phosphine toxicity in some species, the effect is not noticed in the tolerant stages of other species. Sublethal doses of phosphine induce the stored products insects to develop resistance quickly. Recent advances in phosphine dosing methods aiming at complete control are also discussed.
