The Pesticides Act 1999 is the primary legislation controlling the use of pesticides (including herbicides) in NSW and is administered by the NSW Environment Protection Authority (EPA). The underlying principle of the Act is that pesticides must be used only for the purpose described on the product label and all the instructions on the label must be followed. Consequently, all label directions must be read by, or explained to, the user before each use of the pesticide.
All pesticide users should take reasonable care to protect their own health and the health of others when using a pesticide. They should also make every reasonable attempt to prevent damage occurring from the use of a pesticide, such as off-target drift on to sensitive areas or harm to endangered and protected species.
