摘      要：Avocado sadness caused by the Oomycete Phytophthora cinnamomi Rands, is one of the main diseases affecting this fruit crop in Michoacan, Mexico, without having an efficient control strategy for that. In this research three Trichoderma isolates and Ridomil Gold? 4E fungicide were tested in avocado trees infected with this pathogen using the growing and coloring vegetative flow growing. Results were analyzed with an experimental design completely random with four treatments and repetitions. Different responses were presented form avocado trees to each treatment. Trichoderma erinaceum Bissett, Kubicek & Szackacs treatment was the best controlling disease in trees with grade II and III damage. Trichoderma aggressivum Samuels & W. Gams controlled better in trees with grade III damage. At last, Trichoderma arundinaceum Zafari, Graef. and Samuels were the best controlling trees with the highest grade damage. Fungicide Ridomil Gold? 4E controlled the disease in trees with the lowest grade damage (I and II), their medias were similar to witness.
