The effectiveness of aldicarb, fenamiphos, and 1,3-dichloropropene in controlling Hoplolaimus columbus and a combination of H. columbus and Meloidogyne incognita on kenaf (Hibiscus cannabinus) was evaluated in two similar field experiments. One experiment was conducted in a field with a Fuquay sand infested with M. incognita and H. columbus. The second experiment was in a field with a Dothan loamy sand infested with H. columbus but not M. incognita. In the first experiment, in-furrow application of aldicarb at planting at rates of 0.59 and 1.18 kg a.i./ha reduced root galling but also significantly reduced early season plant growth by 23% and 41%, respectively, based on plant weight 21 days after planting. The higher rate of aldicarb also reduced kenaf yield 7 months after planting. Fenamiphos and 1,3-dichloropropene significantly reduced galling caused by M. incognita and increased yield. In both experiments, Hoplolaimus columbus infected and reproduced on kenaf but in the field whe
