Galling from root-knot nematode is present and severity/frequency varies by plot. Severe galling on stunted plants suggests reduced stand is from root-knot nematode.
At mid season, we're assessing nematodes in soil/roots, galling, stand, and canopy vigor to evaluate nematicides.

In this trial we are testing peanut lines for resistance to peanut root-knot nematode. After digging, we rated pods/pegs and roots for galling from root-knot nematode (pictured).

We also assessed pods and roots for galling from root-knot nematode. Raised galls were infrequent. Lots of dark lesions on pods, which can be lighter root-knot, but may also be caused by other factors. Highlights importance of sampling to determine nematode presence.
