The approvals process for pesticides assesses the risk posed to people and the environment from pesticide spray drift. If the risk assessment is not satisfactory then that pesticide use would not be approved.
This rigorous risk assessment process is backed up by a code of practice for using plant protection products (pesticides) which includes a range of practical measures to avoid spray drift. These include using the right spraying techniques and equipment and taking account of weather conditions.
The code emphasises the need to protect members of the public, wildlife and the wider environment. It is the pesticide users’ responsibility to ensure that all reasonable precautions are taken to prevent spray drift. It is a legal requirement that pesticides must only be applied to the land, crop, structure or other area being treated.
