The association of nematodes with cotton yield suppression has been recognized for many years. Atkinson in 1982 (1) noted that the severity of Fusarium wilt of cotton was increased in the presence of the root-knot nematode. This report served as an impetus for research, not only on cotton nematodes, but nematode parasites of many crop species in the United States. Today, almost 100 years after the recognition of the involvement of nematodes in cotton diseases, research continues. Many other nematode species have been added to the spectrum of cotton parasites. Some such as the lance nematodes Hoplolaimus columbus and H. galeatus, the reniform nematode, Rotylenchulus reniformis, and the sting nematode Belonolaimus longicaudatus are recognized on a local or regional basis as economically important cotton parasites. Others, Meloidogyne incognita in particular, are a significant factor in cotton production across the Cotton Belt. A review of the importance of nematodes in cotton has been published (3).
