Hi,
These yellow veins appearing randomly on leaves and then drying up in several areas of leaves as you can see in the picture.
Please help me identify what nutrient deficiency might cause this.
Here is the botanical info of this vine, if it helps.
Botanical name: Cucumis sativus
Family: Cucurbitaceae (Pumpkin family)
Thanks,
Eric
they look like something i've seen - a vine borer or leaf borer.. .. there is a parasite in there .. worm or bug. eating it's way through the leaf - the vein is his trail.
look at these:

I agree, looks like leaf miners not a nutritional deficiency.
When I googled up, I found contradicting information about the leaf miners. Some are mentioning that I can just cut the affected leaves and some are mentioning to leave it as is. I have too many leaves with this issue. So, I don't think it is a good idea to leave it as is.
Is there any suggestions to get rid of this bugs?
Thanks,
Eric
i have no experience with an infestation - we are getting frost every morning and just about every pest is gone till spring.... if the leaves aren't dying and just damaged - perhaps you can spray..
I wish I could help.

Fertilome Borer, Bagworm and Leafminer Spray works and is organic. the active ingredient is Spinosad.
According to Co-operative Extension service info, in most cases once you see that much damage, there is little that can be done short of a systemic treatment which is not recommended for edibles nearing harvest.
Eric, contact your local county agent for recommendations for treatment at this stage. Trackinsand is correct that Spinosad is great for the problem, just not sure about using it on edibles close to harvest.
You may not need to do anything at all at this point--it's pretty late in the year so if the cucumbers are developing OK and you're getting close to picking them you might just leave it alone for this year, make sure you throw out any infected leaves after you've picked all the cukes, and then if you grow these again next year, keep a closer eye out and catch things a little earlier on.
Thanks for all your replies. I have decided to leave it as is because the cucumbers will be ready for picking in 2 weeks.
I will keep in mind about this infection in the next season.
Eric
Good luck - if you have too many send them my way.. the non summer was a dud for cukes in Connecticut.
( it snowed today)
