Importance of labels
The pesticide label is a legal document and penalties can be applied if the pesticide is not used according to the directions on the label. This includes the rate of application, that is, how much you put in the tank, how often you apply it, how you apply it (what sort of spray equipment) and how soon you can harvest the crop after you have used that pesticide.
You can be fined for mis-use, and if many growers are not using a pesticide properly, it may be withdrawn and you will no longer be able to use it.
The withholding period (WHP) listed on the label states how soon after spraying you can pick the crop (not sell it).
If you pick the crop too soon (earlier than the end of the withholding period) it will have residues from the pesticide that are too high for people to eat that food safely. Many retailers including Coles and Woolworths, and government departments, test food at random for residues. If they are found to be too high, you can be prosecuted.
You can also be charged for the cost of recalling your product from the shop, so it can cost you a lot of money. If chemicals are found in your product that are from pesticides that are not registered for use on strawberries, this is illegal and you may also be prosecuted, with your product withdrawn from sale.
The Food Act 2008 and its subsidiary legislation The Food Regulations 2009, has three levels of offence: ‘knowingly’, ‘ought to know’ and ‘Strict liability’ where there is no excuse for not knowing the right thing to do. The penalties range from $40 000 to $100 000 and potential imprisonment for an individual grower, or $200 000 to $500 000 for a company.
When you buy a pesticide, you agree to the legal use of that pesticide as described on the label, and therefore higher penalties may be incurred.
