Survey of ring nematode in South Carolina peanut fields

Abstract

Plain Language SummaryCompared to certain other nematodes, limited research has been reported for ring nematode (Mesocriconema ornatum) in peanut. To explore relationships with soil texture characteristics and to examine samples for consistency of species identity, peanut fields in six South Carolina counties were surveyed for ring nematodes. Peanut ring nematode was found in 59% of examined field samples. Increased numbers of peanut ring nematodes were associated with soils with increased sand content and decreased clay content. Ring nematode samples were identified as Mesocriconema ornatum. Results from this survey serve as a resource and reference for future work.
