Pesticides can pose a threat to the environment and human health during transport and storage, pouring and mixing, application and disposal. Therefore, before carrying out any of these activities all pesticide users must consider what precautions need to be taken to safeguard wildlife, the water environment and human health.
Protecting water is one of the most important considerations when planning any pesticide operation. Pesticides can reach water by 4 main routes:
- run-off from the spray treatment area
- percolation through the soil (leaching)
- spray falling outside the target area (spray drift)
- spillage of concentrated pesticide (whether by accident or neglect, this route can constitute the most significant environmental threat)
Threats to human health
Pesticide pollution may constitute a threat to human health. Work is directed at preventing and minimising this threat. Various measures are used to monitor and encourage compliance with the Pesticides (Jersey) Law 1991:
- controlling and monitoring all pesticide imports
- annually auditing pesticide retailers to ensure their storage facilities meet the requirements, and their personnel are equipped to deal with spillages. Their vehicles are also assessed for suitability, and must be driven by trained drivers carrying emergency spillage equipment
- annually inspecting all farm pesticide stores (the Inspectorate)
- pesticide users are encouraged to consider whether they need to use a pesticide at all. Much work is done to advise growers to adopt whole farm systems, which use cultural, mechanical, and biological methods before targeted pesticide use
