Foliar fertilization and deep-root feeding show promise in strengthening a trees natural immunity to attack by Mountain, Pine, Ips, Spruce and other bark beetles.

While not considered an adequate treatment alone to combat an infestation of bark beetles, fertilization promotes tree health along with natural pitch production, the trees natural defense against boring beetles. Under certain circumstances a tree under attack is able to "Pitch Out" a boring beetle, killing the boring insect by encapsulating the beetle in pitch or sap.

Studies have shown healthier trees to be far more resistant to beetle attack. We believe that foliar or deep-root fertilization combined with a programmed approach to pesticide application to be the most effective means of protecting high-value, specimen and old growth trees.

A Horizon Forestry™ representative would be pleased to evaluate your site, management plan and controls to stop the spread of Mountain, Pine, Ips, Spruce and other bark beetles and determine if foliar or deep-root fertilization is right for you.
