Summary

Trichoderma viride, T. harzianum, Gliocladium roseum, and Paecilomyces variotii were tested in biocontrol trials against several postharvest pathogens and compared with conventional fungicides. Applied as spray treatments to the fruits, these fungi partially controlled Botrytis cinerea in strawbery and kiwifruit, Fusarium oxysporum in potato and Alternaria citri in lemon. Trichoderma demonstrated significant control of artificially inoculated B. cinerea in strawberry but proved ineffective against latent infections. Several strains of Trichoderma were found to be pathogenic in kiwifruit and lemon. All three fungal species gave poor mycelial development at 0, 2, 5 and 10 deg C storage temperatures, resulting in unsuccessful fruit colonization. The overall data indicate some of the difficulties in developing biological control techniques using Trichoderma, Gliocladium and Paecilomyces.
