Analyzed the elements of intensive technologies of potato and spring barley, including the use of herbicides to control weeds and increase the number of yield potato varieties will and spring barley varieties Sontsedar on dark gray forest soils of the western steppes of Ukraine. Established the number of  vegetation in crops segetal cultures during their growing season for the 2014-2016 biennium.

Investigated the relationship between the use of herbicides and quality indicators potato and spring barley. In the field of potato (control) starch content in the average years of study was 1.2 times less compared to the version №6 (Gezagard - 4 l / ha + Panther - 1 l / ha). The content of protein in the grain of spring barley to control an average of 3 years was 1.3 times less compared to the version №6 (Lancelot - 33 g / ha + Aksial - 1 l / ha (phase out the tube).

Established, that productivity of test crops on average 3 years was: potatoes – 10,6t / ha of forage. units. application of herbicides in the version Gezagard - 4 l / ha + Panther - 1 l / ha (+ 34.2% for control), spring barley – 7,2 feed. units. in the version making preparations Lancelot - 33 g / ha + Aksial - 1 l / ha (phase out of the tube) (+ 26,3% for control).
