Abstract
A three-year nematicide study in north Florida, involving four separate cotton field trials, was conducted in loamy sand soils infested with Rotylenchulus reniformis. Cotton lint yield responses and post-harvest soil infestation levels of R. reniformis were evaluated after treatment with four single chisel application rates of 1,3-dichloropropene (1,3-D: 16, 32, 48, and 64 kg a.i./ha) and six rates of aldicarb (0.50, 0.84, 1.01, 1.18, 1.51, and 2.02 kg a.i./ha) placed in a 15-cm-wide band. All rates of 1,3-D increased (P 0.05) lint yields of cotton in three of the four trials compared to the non-treated controls. Post -harvest soil populations of R. reniformis were reduced by 1,3-D treatments in only one of the tests. Aldicarb increased cotton yield (P 0.05) at all rates in one test, and at one rate in a second test. Soil populations of R. reniformis were reduced in only one aldicarb treatment in one of the tests. Average cotton yield across treatments increased by 139 kg/ha with 1,
