In the microplot setting with R. reniformis, the additional fertilizer and nematicide applications did not significantly increase plant height or root fresh weight when data collected at PHS and FB were combined (Table 2). Rotylenchulus reniformis eggs per gram of root were significantly reduced when data collected at PHS and FB were combined for the nematicide ST + 28-0-0-5 + Vydate ® C-LV + Max-In ® Sulfur at PHS application compared to the control application of (NH 4) 2 SO 4 at PHS with no ST nematicide. A significant increase in seed cotton yield was measured with the maximum input combination of the nematicide ST + (NH 4) 2 SO 4 + Vydate ® C-LV + Max-In ® Sulfur applied at PHS and FB when compared to the combination of the nematicide ST + (NH 4) 2 SO 4 applied at PHS (P ≤ 0.10).
