Diplodia Tip Blight is a fungus disease. Now the question is how to treat it? Most pines are tall and if the pine is sprayed for treatment, there is the danger of drift into unwanted areas. When a person is sick, the doctor can give them medicine via an injection or pills and all the medicine ends up inside the body. Not so with tree treatment. Chemicals applied with spray or soil injection do not all end up in the tree. What is the better way for treating conifers and pines for prevention of Diplodia Tip Blight? Use the Wedgle Direct-Inject Tree Injection System with ArborSystems Shepherd Fungicide. For more information, click here.
