Lesion Nematodes on Peanuts

Posted by romeethredge on September 25, 2015

We sometimes in the past have seen lesion nematode, Pratylenchus spp.,effects on peanut pods. It was a cosmetic deal , they just looked spotted with very small spots on the pods. Our main attention and concern was and still should be on the peanut root knot nematode, Meloidogyne  arenaria.

This year I’ve seen peanuts from at least 3 fields however that seem to be adversely affected by lesion nematode. Dr. Bob Kemerait, UGA Extension plant pathologist, visited and said it does seem that the lesion nematode feeding or the subsequent entry of decay organisms in the feeding area caused some of the pods to come off prematurely.

 

In the fields we saw peanuts that were coming off before they could be harvested due to the affected stems.
