he present study aims to evaluate the effect of different doses of the selective herbicide Spotlight Plus on desiccation in soybean. The field experiment was set up in 2022 in the region of Knezha, Northern Bulgaria. Seven treatments, including untreated control, four experimental doses of the selective product Spotlight Plus, and two dose rates of the non-selective product Beloukha with a broad spectrum action, were analyzed. The products were applied with an experimental sprayer Pulvexper at BBCH stage 87. The results showed that using the selective product Spotlight Plus containing 60 g/l carfentrazone-ethyl as a desiccator does not negatively affect the crop's yield quantity or oil content. The application with both of the tested products increased the desiccation rate on pods, stems, and leaves in comparison to the untreated plots and enhanced the crop yield.
