Sabbour M. M., Singer, S. M.
Abstract: Under laboratory conditions, the LC50 recorded 122X104 and 106X104 conidia/ml for the fungi, Paecilomyces fumosoroseus and Paecilomyces lilaceous. , respectively. under semi field conditions the corresponding LC50 136 X104 and 119 X104conidia/ml P. fumosoroseus caused a significant decrease in infestation reached to 21 9.45 and 20 8.12after 90 days of the post applications as compared to 8913.03 and 79 11.12 individuals in the control during season 2012 and 2013. , respectively. The weight of the potato recorded during 2012 were, 5879 8.28 and 5667 7.18 kg/ feddan in the plots treated with P. lilaceous and P. fumosoroseus respectively as compared to 3398 4.29 kg/ feddan in the control during season 2012. During season 2013 the highest weight scored 5992 8.21kg/feddan after treatment with P. lilaceous.
