treatsuddenoakdeath

Agrifos is the only treatment for sudden oak death that works. It works by stimulating the immune system of trees. The easiest way to administer this treatment is with a bark penetrant called pentrabark. This should be used as a basal spray to the lower trunk (only- no leaves) of the tree. Repeat this treatment at least 2-4x per year. This treatment is also good for madrones, redwoods, bays, beech trees, pines etc.... any tree you wish to increase the immune system to fight a decline.
