Grey Box Psyllid Outbreak

[wayne olling]

Greg,

 

In response to your email I advise:

 

In Seven Hills/East Blacktown area there has been widespread recovery of foliage.

 

General observation in other areas west indicate likewise.

 

Tree loss had been from 2-5%, some of which was Council removal which may have been a little hasty given some slow recovery rates with a few trees thought lost.

 

Unscrupulous Arborists were out there telling property owners trees were dying or dead.

 

Most trees have shown high rejuvenation but those trees whick looked really bad are slower in recovery.

 

I must report that a couple of juveniles at the cnr Leabons Lane and Seven Hills Rd South and some more mature trees at Grantham Heritage Park (71 Seven Hills Rd South) which have some lower branches near enough to inspect leaves all showed signs this week of current Lace Lerp activity - not all leaves but some earlier growth mature leaves(i.e. not recovery leaves of a mature shape). However, some of the rejuvenated mature leaves on one of the juveniles at the cnr Leabons Land and Seven Hills Rd South have experienced Lace Lerp activity in recent weeks.

 

Each of the aforesaid observed leaves with Lace Lerp acitivity I subsequently sprayed with White Oil two days ago.

 

Best Wishes,

Wayne
