Update on chemical issues

Paramite Permit

APVMA have granted a minor use permit for the use of Paramite. Paramite (110g/L etoxazole) is used to control mites. For a copy of the permit (PER80893) please contact AMIA.

APVMA & Chemical reviews

Omethoate

The finalisation of the omethoate review is expected within the month. It is understood the outcome is a recommendation to cancel all uses except barrier spraying for Redlegged earth mite and use in ornamentals.

Dimethoate

The finalisation of the dimethoate review is anticipated by mid-2016.

Priority re-evaluation

By December 2016 the APVMA will have completed a re-evaluation of the review priority for the following chemicals: dicofol, propargite, fenbutatin oxide, methomyl, acephate, chlorothalonil, trichlorfon, amitrole, and triazole fungicides. It is understood that the APVMA will decide whether a re-evaluation is necessary or whether areas of concern could be addressed through label amendments.

New reviews

Dithiocarbamates (mancozeb, thiram, ziram) The APVMA is proposing to undertake a detailed scoping exercise for the dithiocarbamate fungicides. As part of this process the APVMA intends establishing a working group to help refine the review scope. The intention will be to invite industry participation in the working group. The scoping exercise is anticipated to start mid-2016.

FSANZ

It is understood that the FSANZ project exploring the possibility of establishing MRLs at low levels to cover situations where inadvertent contamination of by unregistered chemicals is ongoing. The purpose is address situations in which low level residues result in a technical MRL breach but there are no health, safety or trade concerns.

Department of Agriculture Chemical access The first round of the government’s minor use grants scheme is nearing finalisation with successful applicants to be being informed in early 2016. The Department indicates that a call for round two applications is likely to be announced by mid-2016. See: http://www.agriculture.gov.au/ag-farm-food/agvet-chemicals/improved-access-agvetchemicals/agvet-assistance-grants

Regulatory reform

The Department has appointed Deloitte Touche Tohmatsu to review the impacts of work health and safety (WHS) legislation on agvet chemicals. The review is to focus on the duplication of effort and unnecessary costs associated with agvet chemical product compliance with both WHS legislation and agvet chemical legislation. This includes potential duplication of label statements.

To date industry groups have argued that AgVet labels should remain exempt from the addition of WHS elements as they would be superfluous as the risk assessment has already been done by the APVMA and allied agencies when registering a use. Growers aren’t going to be in a position to undertake their own risk assessments based on any hazard statements on a label, so adding additional statements etc would be redundant.

New chemicals

A number of applications have been made to the APVMA seeking registration or active ingredient approvals for new chemicals. BAYER have applied to register the product Serenade Opti ® a combination product consisting of the a biocontrol agent and 1methylcyclopropene as a post-harvest treatment. ADAMA have recently sought to register a new insecticide for use in citrus TRIVOR® Insecticide, a combination of acetamiprid and pyriproxyfen. Syngenta are seeking to have the carboxamide fungicide isopyrazam (SEGURIS FLEXI®) for the control of powdery mildew and black spot in apples and black spot in pears. The company has also sought registration for a new post-harvest fungicide called Chairman® for mould control. It is s combination product of propiconazole and fludioxonil. Agroserve are seeking approval for a Brassinolide plant growth regulator/promoter. ISK are seeking approval for their diamide insecticide cyclaniprole for use in apples. Monsanto are developing a new seed treatment nematicide – Tioxazafen internationally with the first registration anticipated in the US in the latter part of 2016. It is from a new class of nematicidal chemistry and exhibits broad-spectrum activity against cyst, root knot, and reniform nematodes.

INTERNATIONAL

Canada

The Canadian Pest Management Regulatory Agency (PMRA) recently announced a plan to re-evaluate some 65 active ingredients or groups of chemicals and further special reviews of 28 active ingredients from April 2015 to March 2020. Compounds included of potential interest in Australia, from a biosecurity perspective, are: aluminium phosphide, chloropicrin, chlorpyrifos, cypermethrin, deltamethrin, dimethoate, imidacloprid, iprodione, lambda-cyhalothrin, dithiocarbamates and thiamethoxam. To date, review recommendations have been to cancel all methomyl food uses due to dietary intake concerns and cancel a number of uses for chlorothalonil due to OH&S concerns.

USA

The US Environmental Protection Agency (EPA) is currently working towards the cancellation of products containing flubendiamide over concerns that certain metabolites are toxic to aquatic fauna. The compound is registered in Australia in a range of crops for the control of various lepidopteran pests. The EPA has also proposed the revocation of all food MRLs for chlorpyrifos over drinking water aquifer contamination concerns.

Korea

Korea will be implementing a Positive List System for MRLs, in the near future. The first step in the process occurs on January 1st, 2017 when residues above 0.01 mg/kg will not be permitted for non-registered pesticides in Tropical fruit, tree nuts and oil seeds. The system will then be applied to all other commodities from January 1st, 2018. Basically, for a MRL to exist it will need to be a registered use in Korea or have had an import tolerance recently established. Unfortunately, it appears that Codex MRLs will no longer be accepted in the absence of a domestic MRL.
