Abstract The test was conducted at the Macon Ridge Location of the Northeast Research Station in Franklin Parish, LA. Plots (28 ft X 8 rows) were planted on a Gigger-Gilbert silt loam on 15 Jun in a RCB design with 5 replications. Karate 1EC at 0.02 lb (AI)/acre was applied with a high clearance sprayer equipped with a CO2 charged system calibrated to deliver 9.3 gpa at 46 psi and 3.3 mph through TX-8 hollow-cone nozzles (2/row). Application timing for each treatment was determined by selecting and tagging 20 plants from the 2 center rows before spraying. For the 50% and 90% panicle emergence treatments, 10 and 18 plants, respectively, had panicles completely emerged with no open flowers. For the 20, 50 and 90% flowering treatments, 4, 10 and 18 of 20 tagged plants per plot, respectively, had flowering panicles. A panicle was considered to be flowering when the upper 25% portion had open spikelets. Treatments were applied on 28 Jul for the 50 and 90% panicle emergence and on 31 Jul for the 20, 50 and 90% panicle flowering. Sorghum midge damage to seed heads was evaluated on 24 Aug by estimating percent blasted kernels on each tagged plant. Sorghum seed yields were obtained on 8 Sep by manually harvesting panicles from the 20 tagged plants and by mechanically harvesting the entire 2 center rows in each plot.

Abstract Foliar treatments of 2 organophosphates and imidachloprid (Confidor) were evaluated for yellow sugarcane aphid (YSA) and greenbug (GB) control in a research greenhouse at Texas A&M University. Hybrid grain sorghum seedlings (ATx399 × RTx430) were grown in 110-mm germination pots containing a prepared soil mixture composed of peat, vermiculite, and periite in a 2:1:1 ratio, respectively. Four days after plant emergence and 3 d prior to insecticide applications, each seedling plant was infested with 10-20 YSA or GB. There were 5 singleseedling replications for each treatment. Insecticides were applied by using a CO2-pressurized backpack sprayer, through TX-3 hollow-cone nozzles at 35 psi, producing a finished spray volume of 5.6 gpa. Pre-treatment counts of YSA and GB were made the day of insecticide application; post-treatment counts of aphids were made 1, 2, and 3 DAT. Percent control was calculated by using Abbott’s (1925) formula. Data were statistically analyzed by using ANOVA and LSD.
