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.

Ok.. My neighbor uses Sevin dust all the time and swears by it. I
just paid her a visit to see if she had any and she has a bag of
GardenTech Sevin-5 - Ready to use 5% dust. Reading the instructions
on the back shows that the preharvest interval (number of days
between last application and harvest) for grapes is 7 days. I will
find out what brand/strength was given to me. In the meantime
I will write to GardenTech to see what they have to say and will
post their advice.
