An SVB Deterrent Question
 

I was sitting here idly musing about squash for next spring's garden and a thought popped in. The thought that popped in was a quick vision of something like white latex paint like some people use on tree trunks to protect them. Do any of you know if there's something similar that can be painted on squash stems that won't hurt the squash plant but would deter the vine borers via confusion or other?

Would that kaolin base stuff that some people spray on leafy plants to deter bugs work? This area is laced with kaolin mines and in a few parts of this property it's close enough to the top so I could dig some, dry it, pound it into a powder and mix it into a thick slurry or mud to use as a paint. I wonder.....

Any thoughts?
