Topsfield, Ma.

Given the crappy weather we've been having...I'm not worried by what I see in your great pics...no expert either! Some of the yellow blotchiness happens on some
plants and not on others, a genetic thing I think.

BW wipes them out FAST...that's not BW.
The mottling could be Mosaic but the computer I'm on right now has poor resolution.

If there is no pinsect activity, then the best corrective action is time spent patiently doing nothing except weeding & watering with prudence.

Sometimes the hardest thing to do is nothing.

Thanks for the help !.....It seemed to roll out leaf 4 a little futher last night.Its been really cloudy the past 3 days...sun here and there....only sun I saw yesturday was a half hour in the morning and then not after 4 pm.This morning once again foggy and cool....and to answer Andy....Only thing I put on foliage was a quick shot of fungicide a week ago because of the (I quote Duff "Crappy") weather we had.......and it was a prisioner to its own hoophouse with no sun for 6 days.........

I agree. That's not bacterial wilt. I'd say fert burn around the edges and moist conditions/lack of sunlight causing the yellowing and lightening color.

Bacterial wilt will cause your leaves to droop to the point that the plant will look dead in the midday sun. But it will bounce back in the evening....you'll know bacterial wilt when you see it. (Let's hope you don't see it!)

i've had the appearance of fertilizer burn even years after i had quit using synthetic fertilizers. it will usually happen on the hot dry days before the plant gets a chance to get used to that kind of weather.

Even manure will gas off ammonia in toxic levels if cloches (hoop houses) are too small & not ventilated.

Cuke Beetle spend two to three weeks grubbing out on your roots before they emerge in adult form. If significant numbers are present the plant will react, in such a manor that looks like a number, of fungal attacks.

In the Northeast the time, for the underground grubbing out, is now. Dig in and see what you can find. Your investigation will not be anything like the beetle could do with their underground munching.
