Prevent drilling damage when providing trunk injection treatment to your trees.

Use the Wedgle Direct-Inject System which prevents long-term wounding and protects tree health and vitality. The Wedgle is designed to inject the chemical directly into the cambial zone, right where the tree can use it. No air enters the sapwood, so chemical is readily absorbed. The vascular system is undisturbed, maintaining nutrient movement upward and laterally. Multiple or annual treatments can be made without injuring the tree. Drilled holes often extend beyond active layers so chemical is lost in non-active wood where the tree cannot use it. And drilling allows air into the vascular system triggering wound response causing callusing and Compartmentalization Of Decay In Trees (CODIT). For more information, click here.
