Abstract
This study was carried out to find an environmentally accepted method for managing Sclerotinia white mold disease which is considered one of the most important disease affecting beans and attacks a wide range of hosts in worldwide. It affects plants in all stages which causing losses in the field and extends to the store and marketing. Furthermore the difficulty of resistance because it has the ability to colonize the soil for long periods, by configuring sclerotia allow the fungus to survive adverse conditions and provide the main source of initial inoculum.
Salts, micronutrients, antioxidants, bio-agent Trichoderma species were of concern in this study. The research also employed several combinations to develop a strategy prevent sclerotia formation and improve Trichoderma efficacy for disease management.
The results for this investigation are summarized as follow:
1- Islation and identification of sclerotinia sclerotiorum and bioagent:
Isolation and identification of Sclerotinia white mold pathogen from naturally infected bean plants were carried out. Isolation of bio-agent from healthy bean plant samples performed a number of localities at Ismailia governorate (Abo-Sultan, Serabium and Fayed). Isolation trials revealed that eleven isolates belonging to five isolates from Sclerotinia sclerotiorum and six isolates from Trichoderma species, white mold disease was widespread in all tested fields during the seasons of 2011 - 2012.
