Optimising Clearfield and ExpressSun sunflower technologies for Central European conditions

Popis výsledku v původním jazyce

This work compares the efficacy and selectivity of herbicides and tank mix combinations at different application terms in Clearfield and ExpressSun sunflower. Five plot field trials were carried out in Prague. Efficacy of tribenuron (TBM) was excellent and rather rapid on Chenopodium album. Echinochloa crus-galli was not controlled by TBM. Tank-mix combination TBM and propaquizafop (PQF) caused sunflower injury when applied in a very cold growing period. Under dry conditions, PQF efficacy on E. crus-galli was strongly reduced. Split application of TBM, when PQF was used at the second application, was less negatively affected by herbicide antagonisms. Very good results were obtained on plots treated pre-emergence with dimethenamid and post emergence with TBM. Efficacy of imazamox (IZM) on dicot weeds was strongly affected by weeds growth stages and weather conditions during application. Efficacy of IZM on E. crus-galli was increased by oil adjuvant, but this additive reduced IZM selectivity. The best
