Abstract
Purpose. The study aimed to evaluate the impact of various herbicide treatments on Solidago canadensis L. and develop recommendations for its long-term management. Methods. Three chemical control schemes were assessed in 2021–2025: Lintur 70 WG (triasulfuron + dicamba), Roundup Max (glyphosate), and Dianate BASF (dicamba). Treatments were applied using a handheld sprayer during the active vegetative growth phase at a temperature of +20–23 °C and relative humidity of 65–70%. The herbicides' effectiveness was evaluated comprehensively by determining the suppression of the above-ground part, the number of viable shoots, and the ability to regenerate. Statistical analysis was performed using ANOVA with the LSD₀.₀₅ criterion in Statistica 13.0 and Microsoft Excel 2019. Results. The results show that all the herbicides tested have a clear suppressive effect on Solidago canadensis L., although their effectiveness varies considerably depending on the active ingredients and how long they remain effective for. Overall, Lintur 70 WG exhibited the greatest effectiveness, providing rapid and progressive suppression of plant growth, reaching 91.8 ± 3.5% by 42 days after treatment, along with the greatest biomass suppression (86.8 ± 2.7%) and the strongest decrease in shoot density (~90% to 3 shoots/m²), indicates the minimal regeneration ability of the plant. Dianate BASF exhibited moderate but less stable control, with final suppression of 79.3 ± 3.5% and biomass suppression of 69.3 ± 2.6%. The reduction in shoot density (~71% to 6 shoots/m²) suggests partial recovery potential of the species after treatment. Roundup Max demonstrated moderately high yet less sustainable performance, reaching 84.7 ± 3.5% suppression and 57.2 ± 2.4% biomass suppression, with the weakest reduction in shoot density (~63% to 9 shoots/m²), indicating the highest regeneration potential among the tested variants. Conclusions. These findings confirm that multicomponent herbicides with different modes of action are the most effective way to sustainably control S. canadensis, as they ensure rapid biomass suppression and minimal regeneration. The study highlights the importance of considering the physiological responses of plants when predicting the duration of herbicide effectiveness against invasive species. These results could inform the development of chemical management strategies for invasive weeds in Ukrainian agroecosystems and natural habitats.
