Increase of phenolic content is one of the defensive barriers against pathogenic disorders and environmental stresses. In this study the effects of fungal species of arbuscular mycorrhizal species Funneliformis mosseae, Rhizophagus intraradices, Funneliformis caledonius and Tricoderma, Tricoderma harzianum Tricoderma aureoviride on induction of phenolic compounds in pistachio plant Badami Riz Zarand at 0, 36, 72, 132 and 288 hours after nematode inoculation was performed in three replications based on completely randomized design. The results showed that the total phenol content in treated plants had a significant increase compared to the control. Pistachio seedling treated by mycorrhizia at 132 hours and Trichoderma after 72 hours showed slowly increase in at 132 hours post-nematode inoculation and Trichoderma slowly after 72 hours of inoculation, there was a slight increase in phenol content in the presence and absence of the nematode, so that in 288 hours had maximum of increase. Also, the growth factors of leaf number in Mycorrhiza-Trichoderma treatment were equal to 18.53 and 33.33%, respectively, causing an increase in leaf number weight in the presence and absence of nematodes. Also, mycorrhiza treatment compared to healthy control is equal to 24.77% and mycorrhiza-Trichoderma-nematode treatment with 69.19% have the highest number. The studied fungi can be suggested for using in biological control of root-knot nematode.
