Abstract
An assessment of the biological activity of seven soil herbicides (based on seven active substances), permitted for use in soybeans, and their five tank mixtures, is given against the common barnyard grass. The study was carried out in the Primorsky Territory in 2018, 2019 in a greenhouse. The scheme of the experiment is presented: control (without herbicide treatment); Command, EC (active agent clomazone, 480 g/l) at a consumption rate of 1.0 l/ha; Zenkor Ultra, KS (active agent metribuzin, 600 g/l) – 1.0 l/ha; Gezagard, KS (active agent prometrine, 500 g/l) – 3.5 l/ha; Proponite, EC (active agent propisochlor, 720 g/l) – 3.0 l/ha; Dual Gold, EC (active agent S-metolachlor, 960 g/l) – 1.6 l/ha; Gardo Gold, KS (active agent S-metolachlor + terbutylazine, 312.5 + 187.5 g/l) – 4.5 l/ha; Pledge, SP (active agent flumioxazine, 500 g/kg) – 0.12 kg/ha; Gezagard + Dual Gold – 2.5 l/ha + 1.5 l/ha; Zenkor Ultra + Dual Gold – 0.5 l/ha + 1.5 l/ha; Command + Dual Gold – 0.7 l/ha + 1.5 l/ha; Proponite + Pledge – 2.0 l/ha + 0.10 kg/ha; Command + Pledge – 0.7 l/ha + 0.10 kg/ha. Barnyard grass was found to be quite sensitive to most of the herbicides and tank mixtures used in the experiments. Good control of barnyard grass was ensured by the use of herbicides Gezagard, Gardo Gold and Command. However, the extremely high biological efficiency (phytotoxicity) in relation to this species in conditions of a greenhouse and optimum herbicidal potential of soil herbicides, was demonstrated by preparations Dual Gold, Proponit and tank mixtures based on them. In this regard, Dual Gold and Proponit can primarily be recommended for soil application (separately and as part of tank mixtures) in soybean crops heavily contaminated with barnyard grass.
