Abstract

Sampling was done from sesame plants from research field of Vali-e-Asr University of Rafsanjan. Rhizoctonia solani was isolated and identified. These isolates were all multi-nucleotide, pathogenic and belonging to the AG3 anastomosis group. The possibility of biological control of Rhizoctonia rot of sesame was investigated using of Trichoderma harizianum and Rhizophagus intraradices. This experiment was conducted with 7 treatments (inoculated soil with Trichoderma, inoculated soil with arbuscular mycorrhiza, inoculated soil with Trichoderma and arbuscular mycorrhiza, inoculated seed with Trichoderma, inoculated seed with arbuscular mycorrhiza, inoculated seed with Trichoderma and arbuscular mycorrhiza and control without antagonistic agents) and 4 replicates for each treatment. According to the results obtained from different treatments, the inoculated soil with Trichoderma(mean=0.19), the inoculated soil with Trichoderma and arbuscular mycorrhiza(mean=0.193) and the inoculated seed with Trichoderma and Arbuscular mycorrhiza(mean=0.11) showed the highest amounts of disease control.
