In 2017 in the Far Eastern Research Institute of Plant Protection (FERIPP) in field experience conducted registration trials of soil herbicide Gardo Gold at the rate of 4.0 l/ha and studied the effectiveness of a tank mixture Gesagard 2.5 l/ha + Dual Gold 1.5 l/ha when applied before emergence of soybean varieties Sphere. As a standard we used a combination of herbicides Proponit 2.0 l/ha + Pledge 0.1 kg/ha. Recorded high biological effectiveness of Gardo Gold, experienced and standard tank mixtures against a number of annual grass weeds and annual dicotyledonous weed species in hydrothermal conditions of last growing season, favorable enough for the implementation of the herbicidal potential of soil preparations. In such circumstances, their use may be sufficient and the only element of chemical protection of soybean from weeds, or to serve as a basis for the subsequent application of herbicides on vegetative plants.
