Does Surflan need to be watered in?


Surflan AS Herbicide is a concentrate that is to be mixed with water. You do not have to do any additional watering immediately after the application, however a minimum of ½ inch of rain or its equivalent in sprinkler irrigation is necessary to activate Surflan AS Herbicide within 21 days of the application.
