No differences in reniform nematode populations were detected among nematicide treatments on any sampling date. Nematode population counts were subjected to natural logarithm transformation prior to statistical analysis. For simplicity, differences in economic return were evaluated as value of lint cotton per plot minus the cost of the nematicide treatment. None of the nematicide treatments tested reduced nematode population levels as well as the corn or resistant soybean rotation. 1 Statistical analysis performed on natural logarithm transformed data.
Values given are untransformed data.
All other costs of production were the same in all cotton plots.
