The effectiveness of tank mixtures of herbicides with the preparation Plektor for the protection of soybeans in the conditions of the Amur region

Abstract

The data on testing of a new herbicide Plektor, 0.03 kg/ha in the Russian Federation in a mixture with herbicides Paradox, 0.3 l/ha and Corsair, 2 l/ha for the protection of soybeans in the Amur region in 2018-2019 are presented. Processing with tank mixture was carried out in the phase of 2-3 true leaves (t.l) of soybeans. The biological efficiency of the mixtures was 70-86% and exceeded the values of the benchmark (Galaxy Top, 1.5 l/ha + Aramo, 1.5 l/ha, 65-74%). The high efficiency of the mixtures was noted against the pigweed and barnyard millet, while the Plektor mixture 0.03 kg/ha + Pauradox, 0.3 l/ha, showed high efficiency in suppression of the common commeline, and the Plector 0.03 kg/ha + Corsair, 2.0 l/ha + Miura, 0.8 l/ha - of the frost-blite. The yield increase was 4.1 - 4.4 c/ha, the weight of 1000 seeds -166-182 g and the protein content - 34-37%.
