Controlling root knot nematode?

by Diane

I had a problem with root knot nematodes toward the end of the year. All the garden debris was removed, including the infested roots. The soil left bare over the Fall and Winter to 'starve them out'. This year, I would like to start a no-till garden. However, I am concerned that I will not be able to control a reinfestation without tilling. Is there a way to control nematodes with no-till methods?
