This study was conducted to investigate the effect of drift control adjuvants and formulation types on the volumetric droplet size spectra of simulated aerial sprays of propanil. Three polymer-based drift control adjuvants were evaluated with each of two formulations of the herbicide propanil in wind tunnel trials. An invert suspension oil used as a drift control agent was included in the trials. Each of the three polymer-based adjuvants significantly changed the volumetric droplet size spectrum of both the emulsifiable concentrate and the liquid flowable formulations. The invert suspension oil had no effect on the droplet size spectrum of either formulation. Volumetric droplet size distributions given by a laser particle sizer for propanil wind tunnel atomization data were studied using analysis of variance (ANOVA) and Kolmogorov-Smimoff (K-S) statistical tests. The ANOVA considered 6 distribution parameters (D32, Dv0.1, Dv0.5, Dv0.9, D43 and relative span) while the K-S considered the entire distribution. The most frequent agreement was obtained for the K-S test and the ANOVA when considering Dv0.5, Dv0.9 and D43 |
