Tree Program: Eucalyptus pests

Have you seen these little plastic capsules protruding from the base of many eucalyptus trees around the course?  These are used to treat the lerp psyllid which have been a chronic problem at SGCC for many, many years.  The insects cause leave drop, dying back of leading shoots, and a sticky, wax coating which can lead to mold on the leaves.  
We do not treat these trees regularly because of very high costs and only moderate effectiveness of the pesticide.  We did have a case saved up in the shop, so we treated the trees that were most important to aesthetics and playability.  We will continue to monitor the problem and care for the trees the best we can. 

The trees throughout the golf course are going through a major transition.  The redwoods are fading out, other trees are growing too old, and some are not adjusting to the sodium in the soil.  I am pleased to announce that John Harbottle has been hired as the designer of a tree master plan and will begin work in early September.  Golf course architects are an integral part of any construction or renovation project.  They see things that superintendents, golf pros or members would not consider.  I am excited about the possibilities and look forward to playing a role in improving an important part of this fine club.
