EFFECTIVENESS OF THE HERBICIDES IN CROPS SOYBEAN

Abstract

The article presents research results of studying the efficiency of application of soil-applied and postemergent herbicides. The paper contains data on weed infestation of soybean crops 30 days after the application of herbicides and before harvesting, as well as technical effectiveness of herbicides. It was established that 30 days after the application of herbicides the least amount of weeds (7-10 pcs. /m2) was against the background of complex use of subsoil (harnes (1.5 l / ha) + gezagard (2.0 l / ha)) insurance and tank mixtures of postemergent herbicides (achibo (1.5 l / ha) + harmony (6 g / ha) and achibo (1.5 l / ha) + bazahran (2.0 l / ha)). The highest technical effectiveness was provided under the use of soil-applied herbicides (harness (1.5 l / ha) + gezagard (2.0 l / ha)) in combination with a mixture of postemergent herbicides (achibo (1.5 l / ha) + harmony (6 g / ha ) and achibo (1.5 l / ha) + bazahran (2.0 l / ha)). Thus, the technical effectiveness was 90.1 and 89.0 %,30 days after making in process control and before harvesting - 94.5 and 92.8 % respectively
