What does 'off-label use' of an agrichemical mean?
Answer: Using a product on a crop, pest, or in a way not listed on the approved label
Off-label use means applying a product to a crop, pest situation, or in a manner not covered by the EPA-approved label. This is unlawful under the HSNO Act and may result in unregistered residues in produce.
What does 'maximum residue limit' (MRL) mean and why is it important for agrichemical users?
Answer: The maximum legal concentration of an agrichemical residue permitted in food at the point of sale — operators must observe pre-harvest intervals to comply
MRLs are the legal maximum concentrations of agrichemical residues permitted in food. Observing pre-harvest intervals ensures residues fall below MRLs by harvest time.
What does the 'storage' section of an agrichemical label require?
Answer: That the product is stored in its original container, in a locked, ventilated, and secure location away from food, feed, and waterways
Storage requirements protect against accidental exposure, contamination, and environmental release. The original container maintains integrity, ventilation prevents vapour build-up, and security prevents unauthorised access.
An agrichemical label states 'not for use within 200m of waterways'. What does this mean in practice?
Answer: No application should occur within a 200-metre buffer zone from the edge of any waterway
A 200m buffer zone means that no application should take place within 200 metres of any waterway, regardless of conditions. The label instruction is a legal requirement under the HSNO Act.
What does GHS stand for in the context of chemical labelling?
Answer: Globally Harmonised System of Classification and Labelling of Chemicals
GHS stands for the Globally Harmonised System of Classification and Labelling of Chemicals — an internationally developed system used in NZ to standardise hazard communication on labels and SDSs.
What do GHS hazard pictograms on an agrichemical label communicate?
Answer: The type of hazard posed by the product through internationally recognised symbols
GHS pictograms are standardised symbols that communicate the type of hazard at a glance — such as skull and crossbones for acute toxicity, flame for flammability, or dead tree/fish for environmental hazard.
