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

  Please find a link below to download a new disease management guide for non-bearing grapes. As with the other VCE guides, you need to click on the “Preview” icon, which will open a new window, then click on the “Download” icon to obtain a pdf copy. https://resources.ext.vt.edu/contentdetail?contentid=3226&quantity=1&productprice=0&contentname=Fungicide%20Spray%20Guidelines%20for%20Non-bearing%20Vineyards Also, I updated a list of fungicides that you can obtain from home garden centers. 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
