Abstract:
The pistachio gardens in Iran rival other countries with ۲۸۰۰۰۰ hectares and rank first in the world in terms of annual production ۳۰۰,۰۰۰ MTs. Ecological factors for Pistachio planting favor the growth of Aspergillus flavus which produce aflatoxin as secondary metabolites which reduces Pistachio exports. It is important to control A. flavus and its aflatoxin production to increase Pistachio exportation in the country. Soil borne fungi such as Fusarium spp., Phytophthora spp. and verticilium spp. makes also root rot on pistachio trees which resulted yield reduction. It was necessary to find various ways for control management of these fungi to control wilting and inhibit toxic production on pistachio. Soil solarization and biological control application were two best methods for controlling soil borne fungi and A. flavus which are used in many countries. We used soil solarization method for controlling soil borne fungal pathogens in Kerman Application of this method reduced population density of the pathogen from ۱۱۰۰ CFU –g/soil to ۳۰۰ after ۲ weeks and reduced to ۱۰۰ CFU –g/soil after ۴ weeks. This method was simple, effective, no side effect and economic which can be used in nearly warm areas. Keyword: Control, Soil solarization, Aspergillus flavus, Pistachio
