​This presentation provides an overview of harvest aid use in heat-limited environments and shares data from an on-farm evaluation of harvest aids. The trial was established near Sedgwick, Kansas, when cotton was approximately 20% open boll. This timing was within 1 week before the farmer applied harvest aids to the rest of the field. All defoliants evaluated were applied with ethephon and percent defoliation, and percent open bolls were recorded 7 and 14 days after treatment. Two weeks after treatment, defoliation following Folex applications averaged 78% and was greater than defoliation following applications of Aim or Sharpen plus Folex, which averaged 55 and 56%, respectively. Defoliation following application of Sharpen and Reviton ranged from 58 to 70%. Percent open bolls were similar for all treatments and ranged from 70 to 79%.
