Improvement of the integrated protection system of sugar beet crops from weeds in the conditions of the Orel region

The purpose of our work was to study the effectiveness of the use of chemical protection agents and their influence on the yield of Murray hybrid sugar beet in the conditions of the Orel region. On average, over years of the research, the yield on the control plots (without herbicide treatment) was 24.1 t/ha, and the yield of sugar was 3.1 t/ha. This is a small, but quite satisfactory yield on this agrochemical background. In option 2 (using an integrated plant protection system: Betaren Super 1.2 l/ha; Condor 0.03 l/ha; Satellite 0.2 l/ha; Lornet 0.12 l/ha; Imidor 0.1 l/ha ha + Betaren 22 1.5 l/ha, Lornet 0.18 l/ha, Forward 1.2 l/ha, Karachar 0.15 l/ha + Betaren 22 1.5 l/ha, Condor 0.03 l/ha ha, Satellite 0.2 l/ha, Lornet 0.25 l/ha, Kynfos 0.3 l/ha, Forward 1.4 l/ha) the average yield was 30.4 t/ha, and the sugar yield was 3, 9 t/ha. The yield here is higher than in the control group by 6.3 t/ha. The third option turned out to be the most fruitful one. The fractional application of herbicides after the emergence of sugar beet did not affect its vegetation, but it suppressed the growth and development of weeds effectively. The average annual yield was 33.2 t/ha, and the sugar yield was 4.5 t/ha.The obtained experimental data allow to conclude that the system of the integrated weed control used in the experiments with sugar beet crops: Betaren Super 1.2 l/ha; Condor 0.03 l/ha; Satellite 0.2 l/ha; Lornet 0.12 l/ha; Imidor 0.1 l/ha + Betaren 22 1.5 l/ha, Lornet 0.18 l/ha, Forward 1.2 l/ha, Karachar 0.15 l/ha + Betaren 22 1.5 l/ha, Condor 0.03 l/ha, Satellite 0.2 l/ha, Lornet 0.25 l/ha, Kinfos 0.3 l/ha, Forward 1.4 l/ha is highly efficient.
