In this study, four species of Trichoderma in six organic culture medium were cultured. Maximum number of spores was on the broken corn seed medium and related to species T.atroviride . Harvested spores were formulated in three ways. A–T.koningii together sugar beet molasses medium B-T.atroviride selected species after harvesting of corn seeds were encapsulated with three materials include Tragacanth gum, Maltodekstrin, whey powder, with 2. 5, 5, 5 percentages respectively. C-T.atroviride spores with corn seed medium. Formulated spores in molasses after the six months were twofold standard level, Formulated spores in three encapsulating compound after three months were below standard level and spores formulated with corn seed medium after six months was the nearly standard level.
