Hi Frank,
My question would be, if you apply them in the spring, would they attack the
borers that are emerging from the soil? I'm not even sure how the borers
emerge... do they hatch under the soil then crawl up as fully formed moths?
So then, could the nematodes get the moths as they are leaving the soil? Or
are the borers in some other form as they emerge from the soil?
I guess I need to learn more about the complete life cycle of the borers,
and also what is the range of effectiveness of the nematodes.
Thanks for your contributions!
Beth
