Something seems to be killing our cucumbers. Just a few days ago the plants were looking healthy and happy, all the leaves were a nice emerald green.
Now as you can tell by the pic the leaves are turning yellow and wilting. The second pic is something I'm not familiar with. My first thought was that it was some type of fungi, then I noticed that the ground under the plants was covered with june bugs, so that got me to wondering if maybe this was the eggs of the june bug. I squished a couple of them and what looked like a grub worm came out, so now I'm wondering if maybe grubs are the culprit.
I'm pretty sure june bugs lay their eggs in the ground. It looks like some type of wasp nest almost but not really. very strange. The only thing that will kill my cucumbers are squash bugs. The plant always yellows and wilts first. You haven't seen any gray nymphs or stink bugs have you? or little yellow eggs on the underside of leaves?
can you please let me know what do you use to get rid of the bugs from your cucmbers, i have the same problem i barely get 1 or 2 cucumbers in a month and most of my cucmbers leaves are turning yellow like yours. any advise would be appreciated
