An experiment was undertaken to test the hypothesis that AGDISP, a mechanistic model that simulates the landing position of droplets aerially released for pesticide application, overestimates downwind airborne spray concentrations by not accounting f

The retention and distribution of spray droplets within the plant canopy have a crucial effect on the biological efficacy of pesticides. To maximise spray retention, droplets that impact a leaf must remain on the plant. Three outcomes are possible wh

AGDISP uses canopy structure and collection efficiency to model canopy interception but assumes droplets that intercept a leaf surface are retained at that point and do not bounce or shatter. This behavior is not the case for many plant species, part

This article reviews approaches to analytical pesticide deposition modeling for aerial, ground boom, and orchard airblast sprayer applications, and describes modeling approaches including the Lagrangian model commonly used for aerial spraying, which

The distance between flight lines (lane separation) selected for aerial application of herbicides influences both spray deposit variation (expressed as the coefficient of variation or CV) and efficacy of weed control. Increasing lane separation incre

Spray Safe Manager (SSM) is a computer-based aerial application model, which unlike previous models, has a simple user interface. SSM not only predicts spray deposition but also integrates this data with herbicide-plant dose-response curves. This lat

Herbicides are a commonly used forest vegetation management tool, but off-target spray deposition and drift are significant environmental concerns. It is essential that herbicides be applied in a responsible manner, with a clear understanding of how

Since work reported in 2008 developments on the AGDISP ground boom model have improved results against New Zealand field trial drift data and also compare better with ground boom drift data sets from Belgium and Canada The model still predicts more d
