During the recent years the symptoms of spotted tomato, differed from the previously known ones, were found in the Republic Moldova conditions. The fungi of the genus Myrothecium with a frequency of about 30% were found among the fungi isolated from necrotic areas of tomato leaves. It has been established that the fungi of the genus Myrothecium demonstrated a phytotoxic effect on seeds germination, causing of growth oppression and deformation of seedlings rootlets. The sporodochial fluid with conidia suspensions or culture fluids caused the necrosis formation of on the tomato leaves and rapid wilting of isolated tomato shoots. The fungi of the Myrothectium genus exhibited antibiosis and hyperparasitism against the Alternaria alternata fungi. The relationship of fungi Myrothecium with other micromycetes from tomato patches indicates a possible of typical symptoms distortion caused by previously known pathogens.The probability of the Myrothecium dissemination on tomatoes with seminal infection exists. One of the reasons of the enhancing role of Myrothecium infection of tomatoes can be a short rotation of soybean, known as a Myrothecium susceptible culture.
