Quarantine species of stem nematodes are limited in Ukraine

Abstract

In the article, the authors analyzed and systematized the results of research obtained during the processing of domestic and foreign information sources regarding the prevalence, harmfulness, and bioecological features of stem nematode species of limited distribution in Ukraine, which are included in the A2 list by the State Production and Consumer Service. In Ukraine, there are two such species: potato stem nematode (Ditylenchus destructor Thorne) and stem nematode (Ditylenchus dipsaci Filipjev). In contrast to European countries, where the potato stem nematode is not of significant economic importance, in Ukraine its mass distribution in field conditions and the manifestation of the disease d uring the storage of agricultural products lead to significant crop losses. The stem nematode is considered one of the most harmful species of phytonematodes, especially in temperate climates. Without proper control, the stem nematode can lead to a complete loss of the crop (primarily onions, garlic, cereals, strawberries, decorative bulbous plants). D. dipsaci is locally distributed in temperate climates almost all over the world (Europe, North and South America, Africa, Asia, Australia and Oceania), but the species is unable to survive in tropical climates except in some mountainous areas.
