Abstract
Abstract Plots were established in a growers field near Gary, Norman county, MN. Plot size was 4-30 inch rows × 30 ft long. Treatments were replicated 3 times and arranged in a randomized complete block design. The first insecticide application was made 15 Aug with the plants at 30% 5.1 stage of bloom. The second application was made 21 Aug at the 5.7 stage of bloom. Applications were made using a CO2 sprayer using flat fan nozzles, 40 lb psi and applying about 20 gal total material per acre. Daytime application temperature was 70�F both days. The heads from the second and third rows were hand harvested, dried and then crushed. A sample of seeds was removed prior to cleaning and BSM infested seeds counted. The whole plot samples were then cleaned, weighed and yields recorded.
