TREE-äge Insecticide and PHOSPHO-jet Fungicide recently received registration from the California Department of Pesticide Regulation (CDPR), and are now labeled for use in the state. TREE-äge is applied through the Arborjet injection system in which the formulation is sealed inside the tree. Injecting TREE-äge directly into the tree’s vascular system not only provides protection quickly, but is also effective in controlling insects that feed under the bark, according to the manufacturer. TREE-äge provides up to two years of control for insects like emerald ash borer (EAB) and mountain pine beetle. PHOSPHO-jet, a systemic fungicide, helps suppress various plant diseases like sudden oak death, anthracnose, Phytophthora, black spot, scab, fire blight in apple, root rot in avocado and citrus, canker blight and many others. PHOSPHO-jet inhibits fungal cells while eliciting a plant health response from the tree.
