AbstractStudy was conducted in the cold storages unit, Horticulture Department and the laboratories of Plant Protection Dept. College of Agric., Univ. of Baghdad during seasons 2005-2006, the results showed isolation of the genera Alternaria, Aspergillus, Penicillium, Cylindrocarpon, Sclerotinia and Rhizopus from green bean pods stored under 12-18c. This is the first record in Iraq of these genera as pathogenic fungi of green bean pods rot in the stores.The sterilization of green pods and packing them in the netted bags decreased the percentage of microbial decay and total infection severity by the fungi and prolong period of storage to reach 6 days, and showed lower infection severity and low frequency rate of Alternaria and Aspergillus. The genus Penicillium and Cylindrocarpon was not found in this treatment. Polyethylene bags with 16 holes showed less weight loss percent which reached 0.5% and no physiological disorder occurred. The highest pod firmness was 4.8 kg / cm2 found in polyethylene bags with 32

holes after 6 days. No pod cracking was occurred in polyethylene bags with 32 holes and netted bags when sterilized.
