AvoJect is a specialized avocado injecting syringe designed for the application of phosphonate for the prevention of root rot caused by Phytohpthora cinnamomi, the most devastating disease of avocados. Trees of all ages are effected as the disease destroys the fine white feeder root system; there is a gradual decline for older trees, but a dramatic effect for those that are younger. The main application window is in Autumn when leaf flush has hardened and roots are actively growing. An Autumn application can result in high phosphonate root concentrations which ensures root protection for a longer period. The higher concentrations provide good protection for the tree roots through the wetter winter, and results in a healthier root system going into the spring to support the critical flowering period where significant stress is placed on the tree.
