SUMMARY |
Beflubutamid is a selective herbicide used to control broad-leaved weeds in cereals. It has a low aqueous solubility and is quite volatile. There is a low risk of groundwater contamination and it is non-persistent in soil. However it can be quite persistent in water bodies. It has a moderate oral toxicity to mammals and has been shown to cause reproduction or development issues in humans. It is moderately toxic to birds, earthworms and most aquatic organisms. It has a low toxicity to honeybees. |
