SUMMARY |
Azafenidin is a triazolinone herbicide that does not have EU approval for use. It has a low solubility, is semi-volatile and moderately persistent in soil. It does not persist in water in daylight conditions. Whilst the pesticide is not highly toxic to mammals there is a risk of bioaccumulation. Azafenidin shows a low to moderate toxicity to birds, most aquatic organisms and honeybees. |
