Black specs on cucumber

[Jessicalee2104]

One of my cucumber plants has tiny black specs on the underside of the leaves and on the vines in some places. The cucumber blooms and fruits also have these. The cucumber grow but are covered with these black specs, yellow and are no good. What am I dealing with and how do I fix it???

The leaf lesions look like anthracnose. Do the centers of the brown spots drop of and leave holes?

Yes, I have several leaves with holes. How do I treat that?

Some of the holes on the upper leaf looks like something has been chewing it. You do have leaf miner damage as well. The lower leaves do look more fungal. You can try removing the lower leaves, but if the fungal disease keeps moving up the plant, you may have to just pull it. Don't plant the same thing in the same spot.

Look for grass hoppers they eat holes in the leaves. It is interesting how the garden will have a certain type bug this year and a different type bug next year. I shoot grass hoppers with a BB gun. Grass hoppers stay hidden on back side of leaves spray water on leaves that scares them out where they can be seen.
