I never had PM problems until the root aphids vectored it in from my husband's vegetable garden (squashes got it bad last year when they were hit with "regular" aphids). Other than that, I've seen it coming in from gifted cuts to the degree that I've begun to wonder if people give me those cuts to get them straightened out, or what.
If the plants are healthy and the conditions are optimal, it seems to me that it should be a lesser problem, not a greater problem.
Plus, OxiDate has more utilities than just Tx of PM. It's a treatment for the prevention and control of plant pathogens in field-grown crops and commercial greenhouses. Since it's broadly labeled for use as a pre-plant dip, soil drench, foliar treatment, and surface disinfectant that gives a great deal of leeway and alternatives to other treatments and preventatives.
