Effect of different soil and weather conditions on efficacy, selectivity and dissipation of herbicides in sunflower

Popis výsledku v původním jazyce

Six sunflower herbicides were tested at two application rates (1N and 2 N) on three locations (with different soil types) within three years (2015-2017). Efficacy of tested herbicides on Chenopodium album increased with an increasing cation exchange capacity (CEC) of the soil. Efficacy of pendimethalin was 95 %, flurochloridone and aclonifen 94 %, dimethenamid-P 72 %, pethoxamid 49 % and S-metolachlor 47 %. All tested herbicides injured sunflower on sandy soil (Regosol) which had the lowest CEC, especially in wet conditions (phytotoxicity 27 % after 1N application rate). The highest phytotoxicity was recorded after the application of dimethenamid-P (19 % at 1N and 45 % at 2N application rate). Main symptoms of phytotoxicity were leaf deformations and necroses and the damage of growing tips, which led to destruction of some plants. Aclonifen, pethoxamid and S-metolachlor at 1N did not injure sunflower on the soil with the highest CEC (Chernozsem) in any of experimental years. Persistence of tested her
