Dying cucumbers

[escape]

This is Chef Jeff's Whopper Cucumber. Soon after cucumbers form, they go from green to this burnt dried up form within a day. What is happening?

FYI, I am using Espoma organic Garden-Tone 3-4-4 fertilizer, and watering about twice a week.

Oh somebody is sick. Looks fungal to me. I am terrible at picture guessing but that may be advanced powdery mildew, although I would have expected it to be higher as well. See the yellow infection border as it eats on the bottom leaf? It gets inside after a while. What have you got handy for stopping fungus?

Thanks. Yeah, Chef Jeff responded as well, saying it looks like powdery mildew.

I have Ortho 3-in-1 Insect, Mite, and Disease Control spray. It mentions powdery mildew, so I guess I'll try that.

Thanks!

The active in the 3 and 1 is sulphur and very little. It probably has some kind of wetting agent or sticker which is good. Here is a link to a few things you also have that will work and not hurt much organically speaking. I also use betadine, but I am not spraying for PM rather some other nasties and PM just cannot stand it. 2tbsp to a gallon. You might extend your watering a bit also. You have a lot of "stuff" in that soil to keep moisture it appears

Powdery mildew, use cheap mineral water with a pH above 7 and milk at the ration of 5 water - 1 milk and spray both sides of the leaves.
Won't save the leaves affected, but will stop the spores from opening and attacking leaves presently free of the fungus & new growth.
I try to always grow tolerant cultivars.

Nothing to add except that aborted cucumbers look disgusting! I get some on my plants too. Thankfully the leaves all look good and I have some fruit developing.

Let us know how this turns out for you!
