Sf Nematode Studies?
I see on the web that several companies are selling SF Nematodes (Steinernema felitae) to control root-knot nematodes. I have searched to see if there are any scientific studies of the use of SF Nematodes but cannot find any on their effectiveness of how long a treatment works. I would appreciate any suggestions. I contacted the manufacturer but have not heard back (they claim 100% control of root-knot nematodes). Thanks
