The results of studying the effect of the growth stimulants Verva and Verva-El on the growth qualities of pine ordinary seedlings grown under the pre-sowing soil preparation using the roundup (glyphosate) herbicide are presented. The necessity of the presented experiments is connected with the establishment of the impact of the joint effect of new growth-promoting drugs and pesticides traditionally used in forestry on woody plants. It was shown that under laboratory conditions, the simultaneous presence of the roundup herbicide in the growth medium (agaragar) and seed treatment with the growth stimulants Verva and Verva-El leads to an inhibition of the growth of two-week-old pine seedlings, due to a decrease in the size of the roots. In the small-plot field experiment, an increase in the stem height was found in the variants using stimulants relative to this indicator in the variant where the pine was grown only with the use of roundup.
