Rules near water
Anyone applying a pesticide within 30 metres of an open body of water must obtain a pesticide special use approval. Pesticide applicators can apply some pesticides near water by working under the provisions of the Environmental Code of Practice for Pesticides.
A pesticide special use approval is not needed if you are applying a pesticide on cultivated land, which includes:
- improved pasture
- managed turf
- landscaped areas
However, you must follow the product’s label directions. This includes instructions about buffers for aquatic habitats (such as open bodies of water).
