REGDISP Spray Drift Model (v1.3)
REGDISP predicts spray drift deposition from ground application of pesticides based upon regression equations constructed from field data. The user can choose from these established deposition datasets by selecting study year, nozzle, boom height, sprayer speed, and wind speed. REGDISP also includes functionality that allows users to input equations constructed from their own data sets.
REGDISP is a modification of AGDISP 8.26, a tool developed by the USDA Forest Service to predict spray drift from aerial applications of pesticides. REGDISP has been integrated with AGDISP so that the user can choose whether to run AGDISP for aerial or REGDISP for ground applications.
