I can't see to find Captan or flowable mancozeb any longer.
What suggestions do you have for a fungicide schedule that might work.

As far as we've seen, they seem to still be available "over-the-counter" (such as at garden centers), but any other option included in the Virginia Tech home fruit pest management guide may work as substitutes. (It's a long document, but you can keyword search it for "grape" or a specific disease.)

Hello Miri:
If you have seen these available, please send me the source(s). Thank you for the management guide.
Best regards,

You're welcome.
Unfortunately I don't have sources/supplier info to share, as Extension doesn't keep track of this information or recommend particular businesses or brands/products. If a local garden center/nursery doesn't have the right fungicide (look for the active ingredient more so than any specific brand), then you might be able to find it online.
