Insecticide termination rules were evaluated during 2001 in Southeast Arkansas. Insecticide termination treatments, NAWF=5, NAWF=5 + 250 HU, near NAWF=5 + 250 HU, near NAWF=5 + 450 HU, and near NAWF=5 + 550 HU and above were compared, and no statistical differences were detected in lint yield nor net return. Because of low yield potential due to inclement environmental conditions, a slight numerical difference in net return favored insecticide termination at NAWF=5 + 250 HU. No economic benefits were seen by making extra insecticide applications after NAWF=5 + 250 HU.
