New herbicides for protection of sunflower

Results of two-year researches on studying of influence of new herbicides on the basis of an imazamoks on productivity and contamination of sunflower 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 LG5555 KLP hybrid, steady against imidazolinona. The predecessor - a winter wheat. Contamination type - mixed. The prevailing species of weed vegetation: an ambrosia polynnolistny (Ambrósia artemisiifólia), бодяк field (Cirsium arvense), a shchiritsa thrown-back (Amaránthus retrofléxus), a durnishnik ordinary (zobovidny) (Xánthium strumárium), 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 a bodyak field which was suppressed less effectively on option Global, BP of-1,1 l/hectare. The average yield маслосемян sunflower in control was 11,7 c/hectare. On options with use of herbicides reliable rise of productivity of culture have been got: from 67,1 to 73,5%.
