During the past years there has been an increase in the number of tomato greenhouse facilities in Michoacan. The expected high yield for some of these greenhouses has not been attained due mainly to the presence of tomato diseases, which in many cases, the identity of the pathogen is unknown. The objectives of this research were to determine the incidence and the etiology of the main diseases affecting greenhouse grown tomato in central Michoacan. Sampling was carried out in six commercial tomato greenhouses located in four municipalities from March to October 2007. The main diseases detected were wilting of young and mature plants, late blight, bacterial speck and powdery mildew. The identified pathogens were Phytophthora infestans, Oidiopsis taurica, Rhizoctonia spp., Fusarium oxysporum, Oidium neolycopersici and Pseudomonas syringae pv. tomato. Late blight caused by P. infestans and mildew caused by O. neolycopersici were the most important diseases detected due to the high disease incidence and severity. [ABSTRACT FROM AUTHOR]
