Abstract
Abstract This test evaluated the effectiveness of insecticides for the control of TPB in cotton. Plots were 8 rows wide and 50 ft long with 8 untreated rows or a 10 ft planted buffei between plots. Plots were sampled 3 DAT for TPB in squares. Twenty-five randomly selected squares in each plot were sampled by visually observing the number of TBP adults and nymphs in each square. An insecticide application was applied on 9 Aug with a high-clearance spray tractor equipped with two TX4 hollow cone nozzles per row traveling 4 mph and delivering 5 gpa. Plots within a replicate were sprayed sequentially to maintain true replicate integrity.
