The Q&A Archives: Monterey Bay Brush Cherry - Bugs

Question: We have a one year old hedge of 35 plants and there is a little life sucking bug on the leaves that are really small but are making the plants look sickly. What is the best pesticide or solution to solve the problem.


Answer: Syzygium, the brush cherry, is susceptible to an insect called Eugenia psyllid. These are very small jumping insects and an infestation can cause defoliation. There are no foliar sprays registered for homeowner use in the state of California, but there is a predatory wasp that tends to show up when psyllid populations are large. In the meantime, you can partially control the damage by spraying the hedge (upper and lower leaf surfaces) with a strong spray of water. This will dislodge and disorient the pests and stop them from feeding, at least temporarily. You may also want to contact your local Cooperative Extension office to see if they can offer any other solutions. (714-708-1606) Best wishes with your landscape!
