Zucchini Leaf Edges Yellowing + Mold?

9 years ago

Hello,

I have a question about my zucchini plants. A few leaves seem to yellowing around the edges. Additionally, I found a moldy looking spot on one stem base and I included the photo when I pulled the stem. We have gotten a lot of water and the plant is huge so I am not sure if the two are related or if the mold at the base is anything to worry about.

It doesn't look like SVB to me. The plant is still producing and is huge (albeit it does not have enough room in my garden). I don't fertilize, haven't treated with anything, and grew zucchini plants in the other side of the box garden last year without this issue.

Sorry if the photos aren't great - I snapped them quickly.

Thanks!

Looks like you might have spittle bugs and their larvae boring inside the stems too. I also see some possible SVB damage and a couple of possible eggs on a few of the green stems. Can't say for sure as the pic is somewhat blurry. Over all the plant looks good but I'd Google spittle bugs for comparison picks and do a thorough search for SVB eggs and larvae damaged stems. I'd also bury that damaged stem with soil.

Thanks Dave. I split the stem I removed and didn't find anything grub like inside. I'll keep watching. I've been checking for signs of SVB pretty much daily, but the plant is so big and tightly fit it can be tricky. I'm not getting the wilt yet if it is SVB so my only realistic option may be to wait and see and harvest while I can. I don't see the foam/mold anywhere else, which is odd to me.

I have cucumbers for the first time and am hoping I don't have anything that crosses over!
