Evaluation of Selected Insecticides for Control of Stink Bugs in Soybean, 2014

The efficacies of selected insecticides were evaluated against a stink bug complex at the Macon Ridge Research Station (Franklin Parish). Soybeans were planted onto a Gigger silt loam soil on 4 Jun. Plot size was four rows (40-in. on centers) × 40 ft. Treatments were placed in an RCB design with four replications. Insecticides were applied on 3 Sep with a John Deere 6000 tractor and compressed air system calibrated to deliver 10 GPA …

EVALUATION OF SELECTED INSECTICIDES AGAINST TARNISHED PLANT BUGS IN COTTON, 2013

An insecticide efficacy trial was conducted during 2013 at the Northeast Research Station (NERS) near St. Joseph, LA (Tensas Parish). Cotton seed was planted on 40 inch rows into a Commerce silt loam on 30 May at NERS. The test was a RCB design with 4 replicates. Plot size was 4 rows × 50 ft. Insecticides were applied using a John Deere 6000 series high clearance sprayer calibrated to deliver 10 gpa at 3.5 mph with Tee Jet TX-8 hollow cone nozzles (2/row) to all four rows of each plot on 30 Jul and 7 Aug. Post-treatment evaluations were made at 3 and 7 DAT1, and 6 DAT2. Plots were sampled with a standard 2.5 x 2.5 ft black cloth shake sheet by taking two sub-samples from the two center rows of each plot. Data were subjected to ANOVA and means were separated using an F protected LSD (P < 0.10).
