The pathogenic microflora and entomofauna were studied on the Chaenomeles Lindl. cutivars (Maloideae, Rosaceae). In central Russia, the multi-year systematic monitoring of pathogens and phytophages was carried out on plants Ch. japonica, Ch. cathayensis, Ch. ×superba. Among the identified pathogens, the micromycetes belonging to genera Botrytis, Cytospora, Diplocarpon, Entomosporium, Gloeosporium, Monilia, Neonectria, Penicillium, Pestalotia, Phomopsis, Phyllosticta, Septoria and Sphaeropsis were found to be injurious. With age, the accumulation of infectious background, including viral diseases and the damaging entomofauna was noted in the plantings of fruit crop Chaenomeles. The species composition of phytophages is mainly represented by autochthonous species (polyphages and oligophages), preferring the plants of Rosaceae family. Despite the abundance of species in the phytophage complex, it has a little effect on the decorativeness of Ch. japonica, Ch. cathayensis and Ch. × superba.
