Cucurbit and basil downy mildews move into NYS from (usually) the south and are being mapped.  You can check in on the maps yourself or sign up for alerts

While these are more common in field production, I have seen basil downy mildew in greenhouses.

The websites also have links to photo galleries for ID, discussions of threats and risk, and if you really look (I can’t resist anything labeled Interesting Links) – a link to the Mt Olive Pickle Company!
