Default More on Sevin and Japanese beetles

Dave,

When you say "residual effect" do you mean the effect on the JB, or the fact
that Sevin doesn't come off the foliage until a good hard rain? I confess
that I don't know the answer to the first part.


I sort of mean, is it *just* a contact killer, or does it stick around
to kill them several days later when they decide to munch? I suspect I
know the answer to that based on your comment above.

Ironically, even though it wasn't supposed to rain until at least the
weekend, I'm looking at a downpour outside my window right now. So, I
might have to spray again in a day or two, although, maybe it doesn't
count toward the 5 foliar sprays because it was washed off within
hours of application.


As for your second question, it's not an "either or" for me -- I spray JB
first, then the entire plant..... depending on my mood, I give the JB an
extra shot when I'm done! (Wow -- I guess it's a good thing I wasn't into
growing roses when I was young enough for PMS!!! "This one's for you and
the horse you rode in on!" Back then, I was too busy using Diazinon on
radishes, sigh.......)


Well, my concern is the limitation on the number of sprays allowed. If
I need to just do spot sprays, then so be it. I can derive some
pleasure from that. In fact, I'd almost prefer to do that as opposed
to spraying th whole plant. After all, I'm lazy, as everyone around
here knows...

Also, Dave, I misquoted you about the foliar applications; you said they
should be limited to 5, but I typed 4 in my post. I'm still trying to
figure out which is worst: not being able to A) type; B) read; or C) count


I decided not to point out the discrepancy.

I hear ya, Dave! I'm almost (but not quite!!!!) disappointed that I've

seen
fewer Japanese Beetles this year than I recall in the past (no traps this
year), because it was rather gratifying to see the little ba**ards fall

down
after I sprayed them.

BTW, thanks for the warning about no more than 4 foliar applications per
season -- my bottle of Sevin has been in the garage long enough that

the
instruction booklet on the back was long gone, so I had to go online to

find
the darned dosage!


Do you see a residual effect between sprayings? Also, if you start
early in the season, do you just spot spray on the little buggers
themselves, instead of spraying the whole plant?

Well, after my first couple of applications of powdery Sevin, I got
relief for almost a week. Then, the JBs came back in swarms each time.
I finally decided to buy some concentrated Sevin liquid today (mainly
because I didn't like the idea of casting the power to the wind). I
sprayed liberally and saw an almost immediate effect (something I
never saw with Orthonex, Shiva's experience notwithstanding). It
really knocks them down right on the spot!

It says to do no more than 5 foliar applications per season, but they
should be gone for good in about 3 weeks, so I'm hoping that this will
do the trick.
