Research – Current and Planned


What’s on this page?

This page lists current or planned future research (and related work activities) aimed at improving or expanding the characterization and understanding of pesticide spray drift that would be useful for regulatory authorities and other experts. The activities described may include information on:

  • research for further characterizing dust and spray drift formation, deposition, or mitigation from various types of application equipment (technologies) and methods (ground boom, air blast, aerial, other);
  • development of new or improvement of existing models for predicting depositions; and,

The information is provided as PDF documents that include a brief description of the research/work, projected schedule of work and availability of results, research organization, and a contract name and email address.

Objective of sharing spray drift research information

The goal is to improve awareness of spray drift research and related work and to foster greater communication and collaboration of this important technical and regulatory area among researchers, regulatory officials, industry and other individuals. The benefits are manifold:

  • Providing researchers with knowledge about other work that may interest them and could affect or contribute to their work;
  • Providing regulatory authorities (risk assessors, risk managers, decision makers) with knowledge of future work that may contribute to their capabilities for decision-making;
  • Identifying opportunities for collaboration; and
  • Helping to identify additional research needs.
