Thrips Control/Variety Test in Cotton with Temik, 1993

Cotton was planted on 14 May at the University of Arkansas Northeast Research and Extension Center in Keiser, AR. Plots were treated with Terrachlor + Temik or Terrachlor + No Temik using Gandy boxes. Plots were 4, 38-inch rows, 50 ft long arranged in a RCBD design with 4 replications. Ratings were made on 27 May and 3, 9, and 17 Jun. Visual ratings were made on a scale of 1-10 with 10 = severe damage. Thrips were counted by removing 5 plants/plot and washing the plants through a series of sieves, counting the thrips trapped by the last sieve. Plant height and node measurements were also made. Plots were harvested on 29 Sep for first and only pick by harvesting the center 2 rows in each plot.
