Effects of different components of IPM in the management of the potato tuber moth, in storage

Abstract

Different treatments to control potato tuber moth (PTM), Phthorimaea operculella (Zeller) for 2 and 4 months of storing potato tubers were investigated. A granulosis virus (GV) preparation at 5 kg ton-1 of tubers was effective against PTM for up to 2 months of storage, i.e. up to sprouting. Deltamethrin (0.05% at 7.5 kg ton-1 of tubers) was effective for up to 4 months of storage and sprouting and there were very few infestations by the pest in the treated tubers. Bacillus thuringiensis (BT) was ineffective against PTM. Zero to very low pest infestations were achieved with several treatment combinations (GV + BT + deltamethrin + lantana; deltamethrin + BT + GV) even after 4 months of storing tubers of different resistance levels. © 1992.
