Summary:Small-scale laboratory studies to assess the various materials on the various crops and pests at varying rates and spray spectra can identify promising combinations for field evaluation. This work details a laboratory spray table and calibration methodology that allows users to quickly set up and apply material at desired rates and droplet sizes. A series of flat-fan nozzles were evaluated at different speeds and pressure combinations in the spray table. A database of spray volume deposition rates and droplet sizes was developed using water sensitive cards analyzed with the DropletScan software. The developed spray table system can be used to quickly and inexpensively screen a large number of application scenarios to select the application system combinations that show the most promise for field evaluations.
