What do spray the soil with to kill Nematodes?
I had read on this forum that someone had some success spraying a chemical on the soil to kill Nematodes - maybe it was in the fall after the clean up but it seemed to kill them off and prevent a return in the spring. I am in the US for another day and am hoping to be able to find and purchase whatever it was. I'm from Ontario where it is probably banned and I can't purchase it. I've searched through the threads but can't find the reference. Can anyone tell me what the chemical was and where I might find it? Or anything else you do that might help!
