Using pesticides correctly will control pests and diseases effectively, keep you safe and minimise your exposure to the pesticides.
Rules and regulations for pesticide use must be followed to make sure that you, the food you grow, your neighbours and the environment, remain safe.
Using pesticides wrongly or illegally can mean you lose the right to sell your fruit. Your actions could even mean that all growers lose access to some markets.
Once someone has been found to use pesticides incorrectly, they may not be able to buy other pesticides and might not be able to continue in business.
Registration of pesticides
You can only use pesticides that are registered for use on strawberries in Western Australia or that have a current Minor Use Permit for strawberries.
Tables 1 and 2 below list pesticides that are allowed to be used on strawberries in Western Australia as of 12 February 2015, but these can change often and must be checked regularly.
The Australian Pesticides and Veterinary Medicines Authority website is updated daily and can be used to find both registered chemicals and minor use permits.
Using the wrong pesticide may also be a waste of money if it does not control the pest or disease that is causing problems.
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You can be fined for mis-use, and if many growers are not using a pesticide properly, it may be withdrawn and you will no longer be able to use it.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.
