Description
Summary:A random survey of 467 peanut and cotton fields in 17 counties of Southwest Georgia was conducted to determine the frequency of occurrence and distribution of parasitic nematodes associated with peanuts and cotton. Meloidogyne species were present in 9.7% of the peanut field soil samples, Pratylenchus spp. (primarily brachyurus) in 16.9% and Criconemoides ornatus in 97%. Sixty-nine percent of the root-knot associated with peanuts was M. hapla, 25% was M. arenaria and 6% was a mixture of both. Sting nematodes, Belonolaimus spp., were not found in peanut fields in the survey. In cotton soils, 11.8% of the samples contained Meloidogyne spp., 5.1% Hoplolaimus columbus, and 0.7% Rotylenchulus reniformis.
