Free-Flowing is a comment from arborists.

ArborSystems Boxer Insecticide (Chemical: Emamectin Benzoate) has been described as free-flowing, not gummy. Tree care professionals don’t have to stop and clean their Wedgle all the time. But you need to take care of your Wedgle every day and, we make it easy. You can clean it in a bucket of water or with the garden hose adapter to keep it from clogging or corroding. Just as you can treat almost any tree in five minutes or less, cleaning the unit takes minutes too. For more information, click here for how to information and videos.
