Q: I have looked for Nemacide to no avail. Once upon a time it was easily purchased at any garden center but now it is gone.

A: Nemacide was once used to control soil nematodes. Its no longer available due to toxicity issues. Unfortunately, there are no homeowner products registered for nematode control. The best strategy for management is to add organic matter to the soil to enhance the microscopic inhabitants that feed on nematodes.
