Modern herbicides in soybean crops

Learning objects-soybean cultivar Mezenka, herbicides Harmony, Harmony Classic, Аlgorithm. The aim of this work is to study the impact of modern herbicides in the farms of the Oryol region on weeds in crops of soy and its productivity. There were studied the species composition of weeds in crops of soybean research and Education Center (NOPC) "Integration" of federal State educational institution of higher education budget "Oryol State Agrarian University named after N.V. Parakhin». The influence of the weeds of herbicide Almazis, Harmony and Harmony Classic under the prevailing conditions of the economy on plaçe 110 ha. The results showed that in the period of vegetation on experimental field NOPC «Integration» (Orlovsky district of Oryol region) were common weeds Poa family and several families of flowering plants. High efficiency herbicides showed Harmony Classic 0.05 kg/ha-97%, Harmony 0.008 kg/ha (95%) against the background of the use of the herbicide Algorithm 1 l/ha, whereas the only herbicide effectiveness Algorithm showed 56%. Therefore only use herbicide Algorithm proved to be unnecessary and inefficient. Additional use of herbicides Harmony and Harmony Classic has allowed to increase collection of soybeans to 0.3 and 0.5 tons per hectare, respectively applied herbicides.
