5969RE: [AZ] Severe fungus and flies
- Aug 1, 2006The comment "I saw what appears to be small, white, round fungus
attached to branching pats of the stems. Leaves, in two areas have
begun to drop off." appeared to me to be describing azalea scale
also. See http://www.pbase.com/bstelloh/problems and scroll down, to
see pictures of it on some of my plants. It seemed like a really
serious problem, with the leaves drying up and falling off, and the
stems turning black. I eventually discovered a systemic insecticide
containing Imidacloprid and that seemed to fix it.

Azalea Bark Scale- eriococcus azaleae -- White egg sacks in twig

are present, do not spray. Beneficials will usually control this
insect. If heavy infestation -use summer oil spray.

I would think the fungus is due to the increased rainfall/moisture. I
dont know what type of fly would infest an azalea, but undoubtedly
the increased rainfall is helping them breed prolifically. I would
spray with a combination fungicide/insecticide. Safer makes one if
you are wishing to be environmentally gentle. Also available is
plant food with systemic insecticide. Horticultural oils will
temporarily keep bugs away; you have to re-spray after a rain. The
fungus can also be alleviated with some baking soda dissolved in
water (add a drop or two of dishwashing liquid helps the baking
soda stick to the leaves), but, again, must be re-applied after rain.
In my opinion, your best bet is to go to a local nursery (a real
nursery, where they employ horticulturally trained people) and get
their advice on a product to use. Take in a sample of the fungus,
even the fly, in a jar.

This is from the ASK US page, so please send me a CC.
Last week, my mother noticed that her azalea bush was infested with
flies. Yesterday, upon closer inspection, I saw what appears to be
small, white, round fungus attached to branching pats of the stems.
Leaves, in two areas have begun to drop off. The fly situation has
My mom lives in Queens, NY (Zone 6); we have had some very irregular
weather over the past 6 weeks....more than normal rainfall and right
now, extreme heat.
Please advise as to what I can use to save her beautiful azalea.
