New non-bearing grape guide and a list of fungicides for the home garden grapes.

I saw several new products, but unfortunately, many of them do not list grapes on their label, so, the list is identical to the old version. If you know of other products that can be used for home gardens, please let me know. Home-garden-fungicides-2021 Download
