A field trial was carried out for studying the efficiency and selectivity of the soil combined selective herbicide Metofen (metholachlor + oxyfluorfen) and the soil contact herbicide Pledge affecting the leaves, in a fruit-bearing raspberry plantation. The treatment was applied in the second half of March. The following variants were set: 1 Control (untreated, non-weeded); 2. Metofen 120 ml/da; 3. Metofen – 150 ml/da; 4. Pledge 50 WP – 20 g/da; 5. Pledge 50 WP – 40 g/da. The effect of the applied herbicides on the weed species association and their infestation levels, as well as the herbicide selectivity to the raspberry plants, were studied under the conditions of permanent soil wetting. The results showed that the soil herbicides Pledge 50 WP and Metofen demonstrated very good herbicide efficacy at the two applied rates of the same active ingredient. The herbicides Metofen – 120 ml/da and Pledge 50 WP – 20 g/da and 40 g/da showed good selectivity to the raspberry plants and they could be used for weed control. The applied higher rate of Metofen caused phytotoxicity and suppressed the growth of the raspberry plants.
