Pesticide Spray Drift

Introduction

Pesticide spray drift is the wind-induced movement of pesticide droplets or particles (also called vapour) outside the intended target area. The potential impact of spray drift includes:

  • less product being deposited on the target, resulting in reduced efficacy
  • financial loss associated with wasted pesticide and time
  • the risk of injury or damage to human health, susceptible plants (e.g. adjacent crops), non-target organisms (e.g. wild and domestic animals, pollinating insects), the environment or property

Spray Drift Awareness Videos

Some level of drift, either during or after an application, will always occur. However, by understanding the factors that impact drift, much can be done to minimize the effects. Towards that end, OMAF and MRA, in cooperation with CropLife Canada, have created two spray drift awareness videos.

"What is Pesticide Drift?" highlights the causes of spray drift and various factors that impact drift. "Equipment and Methods to Reduce Pesticide Drift" focuses on methods that applicators can do to reduce incidents of drift, ranging from awareness of surroundings to mechanical application equipment modifications.
