Can I keep it at bay long enough to harvest the squash? Right now they are maybe 6" long, a couple have gone soft but there are still several that feel firm. The leaves that aren't infected look great and the vine is still growing like crazy and I see blooms every morning. I just really don't wanna loose these. I already lost my pumpkin plant to it.

Spray with neem oil. I use Montery Brand.

Spray all the leaves, top and bottom and along the stems also. Make sure you spray both healthy and sick leaves.

Spray toward evening when the bees are gone and do not spray if it is too hot. (over 90) That is why I spray in the evening.

Neem will control the mildew but you need to keep spraying. I would spray again three days later and then spray weekly. It should control the mildew. I have to spray all my summer squash and the Neem does work well.

ok great. I will have to get some. Right now all I have is a commercial Fungicide that I have been using. I prefer more natural approach but it was all I had.

You need to treat ASAP. Time is important. If the leaves get too bad nothing will help and it will kill your plant. The idea is too treat those healthy leaves so they don't get infected also.

ok I have sprayed the whole thing a few times this week with this fungicide and I will get some neem.

Neem is what I prefer to use. Not to say it is the only thing you can use. Read the label. Does it list powdery mildew?

yea it lists it and it will do for now but I want natural fixes if at all possible. Thank you for the link

OMRI, Organic Materials Review Institute has 70% neem oil on their ok list. Be careful not to spray it when honeybees or other beneficial insects are present. Apparently it doesn't harm them if it is not sprayed while they are active.

ohh good to know! thank you! I do not want to harm any bees or my benies

Milk in a sprayer applied full strength appears to work well also. It didn't repair my few infected leaves but no other leaves have shown symptoms since I've used it.

Hey Chelle! Thank you!

I am always truly surprised at the success people have had using the milk solution. I have trued it and it never helped for me. I must have some sort of extra strong Powdery Mildew.

LOL maybe. The fungicide I had used before ordering Neem seems to have taken care of it. but if it returns I will try the milk and see what it does and will call in the neem if it doesnt work. Speaking of the squash though, what do you all think when you see this?

I don't think I have seen one that looks like that.

The fungicides don't really cure the mildew, they just contain it. So best to keep up a spray schedule so that it does not come back.

ok will mix up some milk then and see if that keeps it at bay.

When I get these I just pull them off and wait for a new healthy one to arrive on the scene. I just think of these as aborted fruit, although I don't know for sure if that's what's actually happening.

ok sounds feasible to me as I do have a few that are growing large and healthy. I wont over complicate it then
