Palo Verde Tree Dripping Water In Mesa AZ
Insect pests can and do injure the Palo Verde and other desert trees. These pests can damage leaves, twigs, branches, trunks and roots. The most dangerous is the root borer. The Palo Verde Borers are root borers and are rarely seen above ground. Adults are 4" to 6" long with antennae nearly as long as their bodies. Adults are active July through October. Immature larvae feed on roots of Mexican Palo Verde and other non-native trees. Larvae spend up to three years underground feeding on roots over a 7 to 10 year period Palo Verde Borers will gradually kill a tree. Most adult borer females lay eggs from spring through summer. Another class of Insect that usually attacks stressed or damaged desert trees like the Palo Verde are Flatheaded Borers Flatheaded Borers most commonly invade sunburned or otherwise damaged areas along the trunks and branches of trees. Olive-gray adults lay eggs under the bark of damaged areas. The larvae are cream colored and legless and mature to 1 1/2" long. The maturing larvae feed on dead wood and make small tunnels filled with what appears to be sawdust. This damage occurs beneath the bark and can go unnoticed for long periods. Another type of insects is the insects that attack the foliage of desert trees. These include: Acacia whitefly, aphids, and psyllids.
Acacia White Fly actually appears dark gray or black because of a large dark spot on the body. These insects reproduce rapidly and cause significant leaf loss. Aphids are a common and wide spread plant pest that can attack desert species. Aphids are restricted to the succulent new growth on the tips of twigs of desert trees. Aphids reproduce rapidly and can quickly kill small twigs and deposit honey dew (a clear, sticky material excreted by aphids that blackens leaves and twigs).
Psyllids feed by scraping at the undersides of leaves giving the leaves a blotchy, yellowing appearance. Psyllids suck plant juices and produce honeydew, sometimes in crystallized form, on which blackish sooty mold grows. Abundant psyllid infestation can cause defoliate and reduce plant growth.In the summer of 2017 I was called to look at a tree that was dripping water as it turned out I discovered it was infested with spittle bugs something I had not encountered before. So add spittle bugs to the list.
Here is what you need to do if the limbs on your Palo Verde start dripping or dying:
1 have us treat your Palo Verde with medicine that will boost the immune system of the tree. This medicine is injected directly into the trunk - this will get the tree's immune system producing enzymes that dissolve fungus bacteria and viruses.
2 Starting immediately - treat your Palo Verde yearly withBio Advanced Tree and Shrub. (Treat for spittle bugs with Bio Advanced Three In One) In some cases it may take a while to work its way to the top of your tree. Treat your tree annually as the  Palo Verde Borers or the Palo Verde Long Horne Beetles are hard to kill. You can get Bio Advanced Tree and Shrub at Home Depot.
