During the period 2006-2008 in the experimental field of the Experimental station of soybean - Pavlikeni is displayed field trial in non-irrigated conditions for establishing the efficacy and selectivity of the herbicide Diflufenikan - 500 g/l Pelican 50 KS in soybean agrocenosis background in natural mixed type weediness. Results obtained may be generalized in the following more important conclusions: Herbicides Diflufenikan - 500 g/l Pelican 50SC has relatively high selectivity EWRS 2-3 ball and is suitable for treatment of soybean crops after germination before sowing at a dose of culture 125 ml /ha. Herbicide effectiveness Diflufenikan - 500 g/l Pelican 50 KS varies from 73 to 89% on annual dicotyledonous weeds S. nigrum; Amaranthus spp.. Less herbicide effect from 25 to 50% is established under Ch. album and the least from 8 to 52% in the group of weeds annual Monocotyledon Setaria spp., Eh. crus-galli. The increase in grain yield of soybean varies from 11.3 to 106.0% compared to the control variant control - zero and is in direct relation to the effect achieved in the fight against weeds.
