Survey was carried out in different commercial markets i.e  6- October, El-Obour, El-moneeb, El-Lewaa, and Bader City at three times during Autumn and Winter growing season. Illustrated results showed that  S. sclerotiorum and B. cinerea are the most important fungi which recorded higher frequency in all different markets. They recorded 28.5 and 24.9%, respectively . The highest infections were recorded in Autumn  growing season, as compared to Winter growing season. Pathogenicity tests indicated that all isolates of S. sclerotiorum and B. cinerea caused the highest infection in green bean pods under wounded or unwounded technique. Complete inhibition of linear growth of S. sclerotiorum and B. cinerea was obtained with thyme, marjoram, eucalyptus and soft guard at concentration of 3.0%, halfa-gar and artemisia at 1.0%, chitosan at 0.06% and lemongrass at 0.5%. Results indicated that the highest reduction in disease incidence was obtained with thyme at concentration of 3.0%, chitosan at 0.06% and lemongrass at 0.5%. All treatments significantly reduced white and gray mould diseases of green bean pods under different storage conditions when applied either pre or postharvest treatments. The most effective treatments are lemongrass, chitosan, thyme and soft guard, which reduced the white and gray mould diseases during the Autumn and Winter  growing seasons.
