This morning I noticed yellow spots on my cucs :( They were not there yeterday, I am sooo bummed. I was so excited as they have been doing so well and even have nice fruit. Is there anything I can use to stop or slow down this from spreading?
On the fruit or the leaves?
ibarbidahl the spots are on the leaves and getting more every day
It might be root knot nematodes (RKNs). RKNs thrive in our sandy Florida soil and love cucumber roots. If it is RKNs, there's nothing you can do to save this crop and coping with them for future crops is a major battle. You can pull a plant and check the roots for galls -- evidence of RKNs.
hejerry I forgot to mention they are in earthboxes so I do not think nematodes are the problem, but thank you for responding.
