Ethoxysulfuron is mainly taken up by the leaves and is translocated within the plant. After inhibition of plant growth, chlorotic patches develop and spread at first acropetally, then basipetally. The action of the product reaches its conclusion about 3-4 weeks after application with the death of the whole plant. Ethoxysulfuron acts by inhibition of the acetolactate.
