We have our own computer-based spray drift model (SiMoD) which has been developed to support the experimental activities in spray drift and to enable virtual experiments where the cost may be prohibitive.  Model simulations can be useful to highlight where drift mitigation is needed and are increasingly becoming part of the regulatory toolbox.

SiMoD is a research tool, but two other models based on it are in the public domain. These are BROWSE and BREAM2, which model exposure of bystanders and residents to pesticide spray drift.  We can provide support and guidance for using these models in a regulatory context.

A version of SiMod is likely to be made available if it becomes a recognised regulatory model.  If you are interested in using it for R&D, then contact
