hey guys, is it possible to wash mancozeb off grapes? I just put some on and a week later we are into veraison so I won’t make the 63 day before harvest interval. This is just a test batch, not for commercial sale. Thanks.
The PHI is 66 days for mancozeb, but it isn't that different than 63 or even 60 days. If it isn't for sale commercially and you are using it for personal use, then that is "informed consent". I bet the the PHI is so sandbagged hugely anyway there isn't going to be an issue.
I think I will let them hang as long as possible and then wash before crushing. I moved from Connecticut to Arizona and it’s shocking how fast we ripen here. Probably harvest in the next 30 days. Brix is already 15-20.
