The infestation by soil-borne pathogens and autotoxicity are the main restrictions in worldwide muskmelon (Cucumis melon L.) production (Zhuang, 2008; Cheng, 2011).Trichoderma could be of prime importance for biological control management of the replant failure of muskmelon reducing the disease incidence o Fusarium wilt and the effects of autotoxic compounds.Degradation of root exudates and autotoxic compounds by Trichoderma were studied systematically in laboratory and greenhouse.According to the SA plant culture, eighteen Trichoderma strains were found growth advantage in presence of root exudates of muskmelon, and Trichoderma strains (T 8, T 58 and T 120) were screened for degradation of ferulic acid, benzoic acid and cinnamic acid.It was observed that the mixture of spore suspension of Trichoderma strains (T 8, T 58 and T 120) had the degradation function to ferulic acid, benzoic acid and cinnamic acid at 100, 300 μg.mL-1 concentrations, and the maximum degradation was found in treatment with benzoic acid,followed by ferulic acid and cinnamic acid.The results of pot experiments indicated that Trichoderma strains (T 8, T 58 and T 120) through liquid fermentation had alleviation function of autotoxicity due to the three autotoxic compounds.The alleviation increased significantly as a result of inoculation with Trichoderma strains before 3 d of treatments with the three phenolic acids, significantly higher than the treatments without inoculation with Trichoderma strains.
