Abstract

Two programs for controlling PTM were developed, program I included the sex pheromone water traps, and two biocides, Abamedin 1.8% ail() Xentari 10.3% and program II included the sexphermone water traps only . Data showed that the percent reduction of infestation according Hendrson and Telton formula were 97% and 52% for program I and program H , respectively . The mean yield of program I was 21.100 ton / fed. while it was 16.50 ton / fed. for program II compared with 15.9 ton / fed. for the control . Also the results showed that the percent reduction of PTM infestation was 100% for the stored potato yield from program I after 2 months storage , while it reached to 64.81% and 61.85% after the same period of storage in the potato yield from program II when treated with Verotecto and Agerin , respectively.
