I need to control scale on a young tulip tree.
Will Sevin concentrate poured on the ground in the root area do the job?
Sevin Concentrate is used mainly as a foliar treatment. It can be sprayed directly on the tree to treat for scale. If you are wanting to treat systemically, Fertilome Tree & Shrub Insect Drench would be a better option. It is safe to use on your trees. You will use 1 fl. oz. per inch of distance around the trunk.
