Abstract: The optimal conditions are require to market Trichoderma as a biocontrol agent against soilborne fungi and nematodes. These include a proper formulation, an efficient delivery system and alternative methods for application of Trichoderma. In this research, three factors of time were spoted to inoculate in complete randomized design with five repeats for each treatment. In first time factor, Trichoderma fungi and 2000 nematode larvaes was inoculated to the soil so that this soil had been mixed with peat and bran wheat ratio 1% and tomato three-week-seedlings were transmitted to the pots after 18 days. In second time factor, the mixture of mentioned soil was inoculated with fungi and nematode in time of transmission of three-week-seedlings. In third time factor, Trichoderma fungi were inoculated to the mixture of mentioned soil and seedlings were transmitted and 2000 larvaes were inoculated to the soil after 18 days. Disease and growth indices were measured after 45 days. First time factor gave the best control and second time factor gave the worst control. Roots dry weight and plant aerial organs were increased compared to testimonial infected plants, followed by 22-72% and 19-51%, respectively. Galls diameter, nematode penetration and nematode population were reduced compared to testimonial infected plants, followed by 21-70%, 19-72%, 23-68% and 28-69%, respectively. These differences were significant compared to contaminated control in level of five percentages. When nematode exposures against Trichoderma fungi more than 10 days, paralysis in acidic productions aggregation and drop behind to receive to the root and roots protect against nematode attack.
