That is interesting Ray. I got killed with cuke beetles 2 years ago, and none last year.
I do use Ami's preplant dip - Mycogrow, Biotamax and Actinovate.
Definitely did it last year, but 2 years ago I am not sure....
I was eyeballing this kaolin clay product - Surround WP - last year and never did get it.
