Question From: J. Manser - Port Orange, Florida, United States
Q: How effective are beneficial nematodes for treatment of root knot nematodes?
A: Jo I have no personal experience with root knot nematodes. One of the joys of living in the North is they cannot live through the winter. I do know they are difficult to get rid of. This Clemson website has good information on them. http://www.clemson.edu/extension/hgic/pests/plant_pests/veg_fruit/hgic2216.html The Garden's Alive website has a treatment of beneficial nematodes they claim as 100 percent effective. I cannot speak to that claim. I suggest you contact your county extension for information. Good Luck and Happy Yardening
