Variables Affecting Drift from Ground Boom Sprayers
ABSTRACT RESULTS obtained during a 99-test, 3-year study in-volving ten dependent-, nine meteorological-, and nine operational/equipment-variables of spray drift are reported. The five corresponding coefficients of deter-mination for five dependent, drift variables range from 65.6 to 90.2 percent and all five equations were signifi-cant (P = 99 percent). Horizontal wind velocity and noz-zle height were included in all five equations and were the two most important variables in four of the five equa-tions. The importance of each of the 3-4 variables in each equation is assessed. The results reported herein provide applicators new information to direct them toward safer pesticide applications.
