This study was carried out to development the environment-friendly control method of Myzus persicae using Beauveria bassiana and Environment-friendly agricultural materials (EFAM).
Germination rate the dried conidia of B. bassiana was 90 percent at 24-27 ˚C temperature condition. Mortalíty of M. persícae was 56. 7% at 1 X1 07 cfu/ml conidia concentration. Four EFAM such as Pachungtan, Wangjungwang, Newbiodakill, Muginchon were low toxicity to B. bassiana growth. Among them, Muginchon (derris extract) and Wangjungwang (neem extract) could have synergistic effect to aphid mortality when mixing treat with B. bassiana, which protection value was 99% in 3 days after treat.
