Horticulture is a branch of agriculture. Its main task is to obtain biologically valuable high-quality produce. At present, intensive and super-intensive horticulture is a promising trend that can significantly increase yields and reduce production costs at a high planting density of fruit trees. Research in the field of nursery growing is of great importance in the intensification of horticulture, since the laying of intensive fruit orchards is carried out only with high-quality, leveled planting material on clonal rootstocks.

The paper provides an overview of the epidemiology and etiology of canine pyometra. The authors analyze risk factors, clinical manifestations, and clinical forms of the disease and well on some aspects and problems of diagnosing pyometra and diagnostic criteria for the early detection of sepsis signs (a systemic inflammatory reaction) in dogs suffering from pyometra. The main modern methods of pyometra therapy are analyzed. It is emphasized that, at present complete ovariohysterectomy is the most effective and safe method of treating any form of canine pyometra.

The antibacterial activity of 25 samples of essential oils and seven aqueous samples and ethanolic plant extracts was evaluated against the complex of potato blackleg pathogens Dickeya chrysanthemi, Pectobacterium odoriferum, Dickeya didantii and Pectobacterium carotovorum subsp. carotovorum. To identify the described species, studies of pathogens were carried out in vitro with a skin diffusion test on agar, requiring minimal inhibitory (MIC) and minimal bactericidal concentrations (MBC) of essential oils and plant extracts.
