Title: Cucumber disease (2)
Post by: The_Atheling on August 17, 2020, 14:39

Hi there. I’m new, so apologies if this has been covered and I haven’t found it.
My cucumbers develop with scarring. The insides are unaffected. The stems also show some scarring.
One plant wilted overnight and I had to cull it.
Dr Google suggests cucumber beetle as a possibility.  DEFRA says that is notifiable - gulp!  :ohmy:
I haven’t found any of the little blighters on my yellow stickies. They can transmit bacterial infections (the wilt?)
Pictures show the scarring on fruit and stems. The leaves have pinholes (thrips?) and the yellow margins are, I suspect, nutrient burn - I grow in a recycling hydroponic system with toms and peppers and the high EC required for them is not ideal for cukes.
Has anyone had the scarring problem? If so, how was it resolved?
Many thanks
Richard

Hello and welcome to the forum, can I call you Edgar, by the way?  :D

I have had a couple of cucumbers with those marks on the skin, made by small snails here - I caught one gently grazing the other day, I took it for a salty swim  ::) Unless all your cucs are the same I wouldn't be too worried about it.

Hi Lesley. Ha, a Last Kingdom fan or a student of medieval history? Since you can't call me Lord King, Edgar will be just fine...

Sadly, the vast majority of the cukes are like this, even well up the vine. Just been out for another good look and I've found no munching molluscs. I'll take a look this evening/tomorrow morning when its cooler so see if I can find any.
