Last month ( mid June ) I had applied Seven
dust to my grapevine
due to Japanese Beatle infestation. I applied
by hand ( gloved ). I grabbed a handfull at a
time and just tossed it across the whole of the
foliage and grape clusters. Here it is mid July
and I still see some rather rich deposits of
the dust sitting on the clusters. As these
grapes ( type unknown ) are reaching ripeness
they will no doubt be harvested within the next
2 weeks to make wine. Will the residual Seven
dust pose any health threats at this point ?
I've tried rinsing with a garden hose but to no
avail. It is rather "caked" in some areas.
There might have been some moisture on the
grapes when I slung the seven dust causing it
to do so.

I wouldn't eat them.

I hadn't planned on eating them. I wish to
make wine of them. I might
try washing the binches with mild soapy water
and see how they look. Hopefully I can get it
(Sevin) gone... But if'n that don't do it, I
will trash the grapes and not take a chance.

I believe the normal time before harvest is seven
days - BUT - you put on a heavy dose AND on the
fruit. I would call the manufacturer and ask
them. You might also consider getting a back
pack sprayer.

In the future, consider Imidan. It is suppose to
be more friendly to beneficals and it will kill
the beatles. Also, the beatles do not eat the
fruit so there really is no need to use the seven
on them. I only use pesticides on the fruit if I
see a heavy infestation of the Grape Berry Moths.
The beatles eat the youngest shoots at the top of
the canopy, not the older leaves or the fruit.
