| I'm in Alpharetta GA and I'm pretty sure my entire heirloom cucurbit crop has been plagued by downy mildew. The pics I've seen online of it more closely match what I see on my plants than any other disease, pest, infection, etc. I don't water overhead, but we have had a lot of early heat and pop-up thunderstorms which end up keeping the leaves wet.
Now that my plants are infected, is there anything I can do to save them? I'd like to avoid chemical fungicides if at all possible but will use them as a last resort. I sprayed the tops and bottoms of the leaves with neem oil today. Is there anything else I can do? |

| Have you tried a milk-water solution? |

| Lets hope that you have Powdery Mildew and not Downy Mildew. The milk water, baking soda water and copper dusts will help control Powdery Mildew. DM is a different story. It require pretty potent fungicides which are not readily available to home gardeners. Fortunately many modern varieties of cucumber, squash etc have DM resistance. |
