Název v původním jazyce

Efficacy and selectivity of post-emergent application of flumioxazin and oxyfluorfen in sunflower

Popis výsledku v původním jazyce

Efficacy and selectivity small plot field trials were carried out in sunflower in 2008 and 2009. For C. album, an efficacy of 97 % was found after pre-emergent application of flurochloridone + acetochlor; the efficacy of oxyfluorfen was 88 to 95 %; the efficacy of flumioxazin was below 50 %; efficacy of flumioxazin increased to 67 % and 69 %, when surfactants were added. Full control of A. retroflexus was found after all pre-emergent and early post-emergent herbicide treatments. Full control of M. annuawas found only after application of oxyfluorfen. T. arvense was fully controlled by flurochloridone + acetochlor and oxyfluorfen. Selectivity of tested sunflower hybrids to flurochloridone + acetochlor, bifenox and flumioxazin was acceptable. Higher phytotoxicity (23 to 45 %) was recorded when surfactants were added to flumioxazin. The highest phytotoxicity (68 to 81 %) was recorded after the application of oxyfluorfen.
