Efficiency of soil herbicides in a mixed type of corporation of corn

Results of three-year researches on studying of influence of soil herbicides on productivity and contamination of corn in the Rostov region are presented in article. The scheme of experience included three herbicides and control option (without use of herbicides). Experiments were made on a hybrid of NANOSECOND of 2012. The predecessor - a winter wheat. Contamination type - mixed. The prevailing species of weed vegetation: an ambrosia polynnolistny (Ambrósia artemisiifólia), a shchiritsa thrown-back (Amaránthus retrofléxus), a foxtail gray (Setaria glauca). All species of weed plants which are found on the skilled site have shown to herbicides high sensitivity, except for an ambrosia polynnolistny which was suppressed less effectively on Dual Gold option, KS - 1,6 l/hectare. The average yield маслосемян sunflower in three years of researches in control was 11,7 c/hectare. On options with use of herbicides reliable rise of productivity of culture have been got: from 26,7 to 42,9%.
