Default What's eating my trees?

Fred,

There are differences of opinion about the merit of Japanese Beetle traps; I
did not put one up this year, and I've seen fewer JB than usual.

Sevin, either liquid or dust, is a common treatment for JB, but it can make
a mess (white dust or milky film on plants, but it beats having no leaves).
I noticed JB on a weeping Japanese cherry near my roses; the worst JB
problem was at the top of the tree, so my little hand-sprayer was clearly
not going to work.

I used a hose-end sprayer to spray the tree with Orthenex
(insecticide/fungicide combo already on hand for my roses), as I was not
sure that the thicker solution of liquid Sevin would work with the hose-end
sprayer.

My suggestion would be to take down the JB traps, as you may just be
attracting more beetles to your yard.

Get yourself a hose-end sprayer & Orthene or other systemic pesticide &
follow the directions on the bottle.

I arived at several nersreys this evening with my damaged leaves, alas,
after each had closed so I turn here for advice....

I more or less suddenly have a couple of problems in the front yard of my
new (well new to me) home. The yard, and especially the "natural area"

is
a bit overgrown, and has a few large trees, so quite a bit of shade, but

it
features a mature dogwood (about 20ft) which has leaves which are
shriveling, and have quite a bit of brown spots on both top and bottom of
the leaves. I dosed it with Immunox (the only fungicide at Lowes?) a

couple
of weeks ago, but no improvement yet (no worse though). Any
recommendations?

Worse, is the wholesale slaughter of my Japanese Maple trees. I have 2

hear
the front door, and they're being eaten to death by what my coworkers say

is
Japanese Beetles. I noticed the beetles a couple of weeks ago in the
gladiolas - and so hung a bab-a-bug in the natural area, which is catching

a
fair amount, but within the last couple of days, the maples are suddenly
taking it hard. So - what to do there? More traps, some sevin dust?

liquid
pesticides? I don't mind using chemicals, but don't want to damage the
trees any further.

Thanks,
- F
