Phytosanitary monitoring and measures to combat quarantine weeds in northern Kazakhstan

Abstract

Background and Aim. The study aimed to obtain comprehensive information on the distribution and degree of harmfulness of quarantine weeds in the territory of Northern Kazakhstan. The results 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.

Materials and Methods. The research was carried out in 2025. The study used generally accepted plant protection methods in determining the spread of quarantine weeds, as well as the improved Abbot formula in calculating the biological effectiveness of herbicides.

Results. This article presents the results of diagnostics and monitoring of quarantine weeds in Northern Kazakhstan. Quarantine species were monitored in Akmola, North Kazakhstan, Kostanay, and Pavlodar regions. According to the results of surveys, creeping mustard (pink) was found in all of the above regions, and field dodder was detected in Akmola and Pavlodar regions.

Conclusion. The main phases of growth and development of quarantine weeds in the territory of Northern Kazakhstan during the study year occurred from the third decade of April to the third decade of July. The effectiveness of non selective herbicides based on the active ingredient glyphosate, against creeping mustard (pink) ranged from 85.0 to 94.0%.
