In this study, using a completely randomized blocks design in the field, controlling effect of biological agents comprising mustard flour, Trichoderma koningii T18, T. virens T59, T. brevicompactum T30, T. harzianum T56, mixture of four Trichoderma isolates, mustard flour + mixture of four Trichoderma isolates and two commercial biological product of Trichodermin B and Subtilin were evaluated against wheat common bunt caused by Tilletia laevis. According to the infection index, all treatments were able to reduce infection percentage and showed significant differences (P SP - 741 EP - 748 AU - Mehrabi Koshki, M AU - Zafari, D AU - Sharif Nabi, B AD - KW - Wheat common bunt KW - Mustard flour KW - Trichoderma Trichodermin B KW - Subtilin.
