Nematicides are the most widely used control measure in the U.S. Cotton Belt.   Previous research has shown dramatic increases in yield with the use of nematicide treatments to control nematodes.  Nematicides suppress nematode infection of cotton roots early in the growing season, allowing for sufficient root growth and plant development which translates into increased yields. Unfortunately, only a small percentage of cotton producers actively manage nematode problems in Arkansas.  This is largely due to a general lack of knowledge of nematodes (root-knot and reniform) and their yield impacts.  Cost and application hazards are other potential drawbacks to routine management of nematodes and use of nematicides.  To help illustrate the effects of nematodes, nematicide verification strips were applied in multiple cotton fields throughout the cotton producing areas in Arkansas.  These nematicide verification strips will also aide in educating producers about nematodes, application of nematicides, and the potential plant damage and yield loss they can cause in cotton if not managed.
