Thrips

It's time to post about bugs. Got a call at the hotline about T-H-R-I-P-S.

It made me realize that San Antonio has got a really bad thrips problem this year.

Could be the ChilliThrips or Flower Thrips.
It's time to find out!!

I've got plumbago dying back. Read that Chilli Thrips, Scirtothrips dorsalis, was the culprit.

Here is a link from the University of Florida about Chilli Thrips:

A link about roses and Chilli Thrips

About all I can say is Yuck!!! Is there any hope for my roses? Hardly a bloom this year.
Do I fight?

Bacterial Leaf Scorch of Shade Trees

http://www.apsnet.org/education/LessonsPlantPath/BLS/default.htm

Article compares, Leaf Scorch due to abiotic stress with biotic stress. Lists symptoms of both.

Bacterial Leaf Scorch is a vascular disease.

BLS is one of a group of diseases caused by Xylella fastidiosa.

BLS of oak may be confused with oak wilt, another vascular disease. Like BLS, initial symptoms of oak wilt appear as scorched leaves. Unlike BLS, however, scorching appears in spring to early summer, and trees defoliate and die within several months after symptoms appear.
