My Pollinated Cucumbers Are Not Growing and Cucumber Beetle

agee12 · July 22, 2017

I have two established cucumber plants that I harvested 2 cucumbers from. I currently have multiple cucumbers that were pollinated for at least a week but are not growing. Why is this happening, could it be heat related? I'm in Georgia and the temperatures have been in the high 80s and low 90s for the past couple of weeks.

This evening I noticed this cute little bug on one of my younger cucumber plants, but then it hit me that it was probably a cucumber beetle - it looked like a ladybug but more yellow-ish than red. The plants have not started flowering. I had DE with me as I was doing my evening inspection and dusting, so I dusted that specific plant along with my other younger cucumber plants - I am kicking myself for not including the cucumber plants when I do my daily walkthroughs.

I planned on transplanting the younger cucumbers this weekend before I made this discovery. My question is are there measures that I can take to eliminate/control the cucumber beetles and their larvae? Note I've only seen this one beetle but I don't want to take the chance that more will come, hopefully the the non-growth issue I noted above

When I do indoor planting I add hydrogen peroxide to deal with larvae, will this work for outdoor plants?

Another thought / idea is adding DE to the planting hole in hopes that it will take care of the larvae, in addition to dusting the parts of the plant that are above ground with DE.

Are these the correct measures?

Should I be doing something else?
