p.1729-1741. Spinosad compounds (Tracer 24% SC, Spinosad 0.125% WP), the bacterial pathogen Bacillus thuringiensis (St) in forms of Protecto 10% and Dipel2x, the Granulosis virus (GV) (Virotecto 4% and the natural infected larvae of PTM with (GV), Fars 5% E.C. an antimoulting compound (IGR), rice straw treated with Cidial 50% EC (an organophosphate insecticide) and the chemical insecticide Cypermethrin 10% E.C. (Pyrothroid) were evaluated to suppress potato tuber moth .(PTM) Phthorimaea operculella (Zeller) on stored potato tubers in open field. The best reduction through all treatments, for both tuber infestations and gallery numbers during the whole storing period was related to Tracer with both rates (7.5 and 5 ml/ton). Spinosad treatment came on the 2nd rank, Fars in the 3rd rank, followed by Dipel 2x and GV infected larvae in the 4th rank. Using rice straw treated with Cidial gave a considerable reduction for both tuber infestations and gallery numbers. Very close reduction was recorded between Virotecto and Protecto for tuber infestation and gallery numbers. The Cypermethrin treatment proved ineffective at the final storing period. So, either Tracer 24% S.C at rate of 5mljton or Spinosad 0.125% WP at a rate of 1kgjton could be a good tool for protecting potato tubers during the whole storing period. Also. the antimoulting agent Fars could be a good tool and in the same time much safer than the chemical ones. Includes references. Summary in Arabic.
