Re: Insect problems-ISOTOX = POISON
Frank, I thought that these nematodes would stay in your soil for up to 2 years
by killing hundreds of varieties of harmful insects. Why would you not apply
them in the spring at planting time, then they have the whole summer to seek out
their hosts. I know that this is what is advertised by "Scanmask" produced by
"Biologic" . If your soil is inoculated early enough, all "pests" should be
eliminated by these predators......Ken Reinsborough
