Effects of Droplet Size on Insecticide Efficacy of Thrips

Experiments were conducted in 2016 and 2017 at the R.R. Foil Plant Science Research Center in Starkville, MS and the Blackbelt Branch Experiment Station in Brooksville, MS. Droplet sizes used in testing included 150, 200, 300, 400, and 500 micron droplets. Applications were made utilizing a pulse width modulating sprayer which allowed an exact PSI to be used during application. data collected included thrips samples pre application and post application. As well as plant biomass 5 days after application. Additional data collected during this experiment included plant height, total nodes, and nawf @ first bloom. Data collection at the end of the year included plant height, total nodes,nacb and lint yield at the end of the growing season.
