2015 Defoliation Strip Trial In Gibson County
DR. TYSON RAPER
JACKSON, TENN.
Mr. Philip Shelby (Gibson County AG Extension Agent) and I put a defoliation strip trial out on Mr. Jason Luckey’s farm last Thursday (9/17). This plot is flagged on all four corners with large red bicycle flags. The southwest corner is located near coordinates: 35.797906°, -88.835526°. Navigating to 36 Esquire Peek Rd in Humboldt, TN 38343 and looking north will put you roughly 100 yards south of the plot. Treatments target a one-shot approach to defoliation with need for regrowth control. Products tested include Daze (thidiazuron), Folex (tribufos), Prep (ethephon), Finish (ethephon+cyclanilide), Terminate (ethephon + cyclanilide) and Ginstar (thidiazuron + diuron) in a number of combinations and rates. Plots are 4 rows wide and roughly 200 ft in length. Each plot is flagged in the southwestern corner with treatment number. The treatment list for all 16 different combinations can be found by clicking here. I will be rating the plots at the end of the week and plan to pass along results.
Special thanks to Mr. Jason Luckey for allowing us to conduct this work on his farm. Additionally, thanks to AMVAC, Bayer CropScience and Nufarm for donating product for this work. ∆
