Phytosanitary monitoring and measures to combat quarantine weeds in northern Kazakhstan

Abstract

This article presents the results of diagnostics and monitoring of quarantine weed species in the territory of Northern Kazakhstan. Surveys of quarantine objects were conducted in the Akmola, North Kazakhstan, Kostanay, and Pavlodar regions. Based on the outcomes of the research, Acroptilon repens was detected in all of the aforementioned regions, while field dodder was found in the Akmola and Pavlodar regions.

Acroptilon repens (L.) DC. is a root-sprouting perennial belonging to the Compositae family (formerly Compositae). In many countries, it is classified as a quarantine weed. Dodders (Cuscuta spp.) are annual herbaceous twining plants belonging to the group of obligate parasites and are widely distributed worldwide. In the northern regions of Kazakhstan, the distribution of dodder is insignificant; it mainly grows along roadsides, along ravines, near railway tracks, on river banks, and on lands of the state forest fund.

The present study is aimed at obtaining comprehensive information on the spread and degree of harmfulness of quarantine weeds in the territory of Northern Kazakhstan. The data obtained will serve as a basis for assessing the phytosanitary status of the region and developing effective measures to control and limit the spread of these species.
