Therefore their isolation and identification could be helpful for applying them in biological control. They isolate by pour soil diluted suspension on Dawet, Peptone – Rose Bengal, or modified Potato- Dextrose-Agar mediums. Species can identify based on colony characteristics, growth characteristics and morphological characteristics of conidiophores, phialids, and conidia. Eighty-five isolates of Trichoderma from 25 soil samples, from 8 regions of the Fars province sugar beet fields, isolated and purified with this method. With studied their characteristics eight form-species of Trichoderma identified with names: T. asperellum, T. atroviride, T. brevicompactum, T. harzianum, T. longibrachiatum, T. spirale, T. tomentosum and T. virens . Methods of isolation, identification and morphological characteristics of these fungi described.
