Agrochemical update: APVMA announces final decision on chlorpyrifos – use on grapevines to end

9 October 2024

In a Special Gazette dated 3 October 2024, The Australian Pesticides and Veterinary Medicines Authority (APVMA) handed down its final regulatory decision on the organophosphate insecticide chlorpyrifos. This AWRI eBulletin summarises implications of this decision for the wine industry.

Decision and implications for use
The APVMA has determined that as of 30 September 2024, the continued use of chlorpyrifos on grapevines is NOT SUPPORTED. A 12-month phase-out period has now begun, where products bearing the previously approved labels may continue to be sold and used. After 30 September 2025, it will be an offence to have possession or custody of, supply, or to use the cancelled active constituents, chemical products and products bearing the previously approved labels.

Aligned with current recommendations in the Agrochemicals registered for use in Australian viticulture 24/25 (‘Dog book’) and as a result of this final decision, any vineyard owners considering applications of chlorpyrifos stock on hand prior to 30 September 2025 must do so in consultation with their winery/grape purchaser.

Maximum residue limits (MRLs)
MRLs for registered uses not supported by the APVMA’s final review on chlorpyrifos will be deleted after the phase-out period. For grapes (both wine-grapes and table grapes), Australia’s current temporary MRL for chlorpyrifos of 1 mg/kg will be removed after 30 September 2025, effectively meaning a ‘nil detect’ will be in place.

‘Dog book’
The current online version of Agrochemicals registered for use in Australian viticulture 24/25 (‘Dog book’) will remain unchanged as a result of the APVMA’s final decision on chlorpyrifos, given there is a one-year phase-out period applicable for use on grapevines. Changes will be included in the 2025/26 version.

Managing custody of de-registered agrochemicals awaiting disposal
The following steps should be followed to safely manage storage and disposal of de-registered agrochemicals and fulfil requirements of certified membership of Sustainable Winegrowing Australia:

  • Segregate de-registered products awaiting disposal to avoid accidental use.
  • Register these products for collection with ChemClear via phone 1800 008 182 or online. You will need to know the manufacturer’s name, product name, product registration number, size (volume) of the container, an estimation of the remaining quantity, and the condition of the container.
  • Apply storage stickers to the containers awaiting disposal. These will be issued to you by ChemClear displaying your registration reference number.
  • Retain a current Safety Data Sheet (SDS) for each product awaiting collection.
  • As part of your chemical inventory, retain records of the ChemClear disposal lodgement, including date, product name, active and volume awaiting disposal.
  • Retain record of disposal once ChemClear collection has been completed.

Note: to determine the product registration number, enter ‘chlorpyrifos’ into the search box on the APVMA PubCRIS database. Under ‘search terms to include’, tick ‘active constituent’, then press the ‘search’ button. A product list will be displayed showing the registration number as ‘No.’ for each product name.

Background to the decision
The APVMA’s final decision has removed most agricultural and urban pest control uses of chlorpyrifos (79 of 91 uses), due to worker health and safety and environmental risks. A summary of these assessment outcomes is available on the APVMA website. This final decision follows the APVMA’s cancellation of registrations of all home and domestic garden products containing chlorpyrifos in 2019.

In the wine industry, application of broad-spectrum insecticides such as chlorpyrifos has declined significantly and wine companies for many years have imposed restrictions on the use of this type of agrochemical. Notwithstanding, prior to this final regulatory decision, products containing chlorpyrifos were registered for use on grapevines against a range of pests – grapevine moth, grapevine scale, light brown apple moth, mealybug, tuber mealybug – and for use on grapevine rootlings against African black beetle. Alternative control options for most of these pests are listed in the 2024/25 ‘Dog book’.

Chlorpyrifos active constituents, chemical products and labels were first nominated for review in 1994 due to possible risks associated with worker health and safety, residues in food and risks to the environment, with the formal review commencing in 1996. Interim and draft reports were subsequently released in January 2000 and in December 2023, prior to the Final Review Technical Report in October 2024, from which the above summary is drawn.
