Agricultural Update July 2008

9 July 2008 >

The AWRI publication Agrochemicals registered for use in Australian viticulture 2008/2009 is now available.

Major changes in the 2008/2009 Dog Book

1. TABLES

Table 1. Recommendations

Active constituents and products

There have been a number of product changes but there have been no changes in the active constituents i.e. there were no new active constituents and none of the existing active constituents were removed.

Restrictions on use

The major change to note is the recommended export withholding period for carbendazim.

The 2008/2009 restriction on the use of products which contain the active constituent carbendazim is Not recommended for use on grapes destined for export wines.

New pests

In table one there is now an entry for the Australian Plague Locust and Wingless Grasshoppers.

Format

The format of the table has had some minor revision. Table 1: Recommendations now lists the major pests and diseases and their restriction on use according to chemical type. Therefore, the diseases controlled by fungicides are listed first and the pest and/or diseases controlled by insecticides are listed second. Within each category the pest or disease is listed in alphabetical order.

Table 2: Agrochemicals registered for use in Australian viticulture

Active constituents and products

There have been a number of product changes but there have been no changes in the active constituents i.e. there were no new active constituents and none of the existing active constituents were removed.

Activity groups

There have been some minor changes to the herbicide activity groups.

Amitrole was Group F it is now group Q.

Dichlobenil and isoxaben were Group K but are now Group O.

Format

The format of the table has had some minor revision. The active constituent categories are now in alphabetical order i.e. Fungicides, Herbicides, Insecticides and Plant Growth Regulators.

2. PRODUCTS

APVMA 52546

The Australian Pesticides and Veterinary Medicines Authority have approved an extension of the Avatar label to include the use of Avatar to control Wingless Grasshoppers and suppress Earwig populations in grapevines. Avatar previously only had a registration for LBAM, Garden Weevil and Grapevine Moth.

Avatar is a DuPont product. It contains the active constituent indoxacarb which is a group 22A insecticide.

Restriction on use for export grapes: Use no later than E-L 31 (before bunch closure), but do not use later than 8 weeks before harvest.

APVMA 62042

Alliance has been granted registration by the Australian Pesticides and Veterinary Medicines Authority for the control of weeds in vineyards. This product does not appear in the 2008/2009 agrochemical booklet as registration was not received until after the booklet was published.

Alliance is a Crop Care product. It contains the active constituents amitrole and paraquat which are Group Q and L herbicides respectively.

3. PERMITS

AWRI: Permit 10127

Permit 10127 replaces permit 7810. Permit 10127 currently issued by the Australian Pesticides and Veterinary Medicines Authority, allows the use of Sumi-Alpha Flex (containing 50 g/L esfenvalerate as its only active constituent) for the control of Garden weevil in grapevines grown in Tasmania and Western Australia.

For other permit information visit the AWRI agrochemical website http://www.awri.com.au/agrochemicals/

4. OTHER AGROCHEMICAL ISSUES

Surround and Screen do not require APVMA registration.

Due to another hot and dry season, the use of products such as Surround and Screen were being considered as a way of reducing leaf temperatures relative to ambient temperatures.

Surround and Screen as protectants against sunburn and heat stress are not required to be registered by the APVMA and there is no State or Territory legislation regulating their use. The registration process is governed by Commonwealth legislation. The agricultural chemical products that require registration encompasses all herbicides, insecticides, fungicides and growth regulators. It does not include products such as Surround and Screen because they do not fit the definition of an agricultural chemical product (For more information on this definition go to http://www.apvma.gov.au/registration/chemreg.shtml). Therefore, Surround and Screen can be used on grapevines despite the fact that grapevines do not appear on the label. Given the nature of the product, residues might be present at harvest, especially in the case of late season applications. We do not know if this will have any impact on the winemaking process and final wine quality. It is advised that you contact your winery or grape purchaser prior to application of these products.

5. AWRI Online Search Facility for Agrochemicals.

The AWRI has been supporting grapegrowers and winemakers for more than two decades with comprehensive information of what and when to spray your vines. To make the information easier for you to access, the AWRI has developed an ‘Online Search Facility for Agrochemicals’ which provides a searchable web-based format, delivering a more efficient way of retrieving agrochemical information currently available on the AWRI website.

Using this facility, users can rapidly access information contained in the current AWRI publication Agrochemicals registered for use in Australian viticulture (often called the Dog Book). It also provides additional information derived from the AWRI agrochemical database which is not published in the Dog book. Further information will be added in future enhancements to the search facility.

The new AWRI Online Search Facility for Agrochemicals can be accessed by visiting the agrochemical section of the AWRI website http://www.awri.com.au/industry_support/viticulture/agrochemicals/

Agrochemical update November No. 2 2007

19 November 2007 >

New Carbendazim label instructions

Products containing carbendazim are still registered for use in viticulture. However, carbendazim products bearing the old label can only be used if a copy of the additional APVMA instructions are securely affixed to the container. These new instructions are no longer available on the APVMA website as was indicated in the July agrochemical update re suspended carbendazim labels. For those who may require this information there are two additions to the label and they are as follows:

  1. The addition of a warning statement to the label.
    Warning: Contains carbendazim which causes birth defects in laboratory animals. Women of childbearing age should avoid contact with carbendazim.
  2. Chemical handlers are required to wear a half facepiece respirator and the amended safety directions reflect this.
    Safety directions: Harmful if inhaled or swallowed. Will irritate the eyes and skin. Do not inhale vapour or spray mist. When opening the container, preparing spray and using the prepared spray wear cotton overalls buttoned to the neck and wrist, a washable hat, elbow length PVC gloves and a half facepiece respirator. After use and before eating, drinking and smoking wash hands, arms and face thoroughly with soap and water. After each days use, wash gloves and contaminated clothing.

Permits can be downloaded from the APVMA website http://www.apvma.gov.au/index.asp

MRL for tetraconazole

The fungicide Domark 40ME which contains the active constituent tetraconazole was registered for use against powdery mildew on grapevines by the APVMA in 2006. During the 2006/2007 season no MRL had been gazetted in the Australia New Zealand Food Standards Code. Therefore, no detectable residue of tetraconazole was allowed in Australian wine. However, an MRL of 0.5 mg/kg has now been gazetted in the Australia New Zealand Food Standards Code and is in place for the 2007/2008 season.

Agrochemical update July 2007

8 August 2007 >

Carbendazim label suspensions

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has suspended label approvals for products containing the active constituent carbendazim. This includes products containing carbendazim that are registered for use in viticulture (e.g. Bavistin FL, Boomer, Carbendazim 500, Carbendazim 500 SC, Carbendazim 500 WP, Carbendon SC, Goldazim 500 SC, Howzat SC and Spin Flo).

The reason for the suspension is that instructions on currently approved labels for carbendazim products may no longer be adequate. They do not contain instructions advising of the potential birth defect risks for pregnant women and women of childbearing age who may come into contact with carbendazim products.

Products containing carbendazim are still registered for use in viticulture. However, they can only be used if a copy of additional APVMA instructions are securely affixed to the container. These new instructions provide information on worker safety and issues the warning Contains carbendazim which causes birth defects in laboratory animals. Women of childbearing age should avoid contact with carbendazim.

You will find a copy of the new label instructions that must be affixed to any carbendazim product at the APVMA chemical review program web site. See June – Carbendazim label suspensions.

APVMA 53738

Py Bo insecticide is registered by the APVMA for the control of aphids, ants, cabbage moth and other caterpillars, earwigs, leafhoppers, thrips and whiteflies in fruit and vegetable crops. Grapevines are considered as a fruit crop therefore, this product can be used on grapevines.

Py Bo is a Pestech Australia product. It contains two active constituents: pyrethrins (Group 3A) and piperonyl butoxide (benzodioxile). Piperonyl butoxide restricts an enzyme that insects use to detoxify the pyrethrins which allows the insecticide to be more effective.

Restriction on use for export grapes: Use no later than 80% capfall.

APVMA 60504

The herbicide active Glyphosate MEA is a new form of glyphosate (MEA = monoethanolamine salt).

SOME NEW PRODUCTS

Microsul WG Elite is a Melpat product. It contains the active constituent sulphur which is a Group Y fungicide/miticide.

Restriction on use for export grapes: Use no later than 30 days before harvest.

Note: The use of generic terms such as mites and vine mites on many of the sulphur products registered for use in viticulture, encompasses all mites that are found on grapevines.

APVMA 52546

Avatar has been granted registration by the Australian Pesticides and Veterinary Medicines Authority for the control of Garden Weevil and Grapevine Moth on grapevines (wine grapes only). Avatar previously only had a registration for LBAM.

Avatar is a DuPont product. It contains the active constituent indoxacarb which is a group 22A insecticide.

Restriction on use for export grapes: Use no later than E-L 31 (before bunch closure), but do not use later than 8 weeks before harvest.

Correction to the copper oxychloride entry: The 2007/2008 Dog Book lists Copper Oxychloride WG under the copper oxychloride active as one of the products. Copper Oxychloride WG should be removed as it is a WP formulation.

PERMITS

AWRI: Permit 7810

Permit 7910 which is currently issued by the Australian Pesticides and Veterinary Medicines Authority, allows the use of Sumi-Alpha Flex (50g/L esfenvalerate) and Sumi-Alpha 19EC (19 g/L esfenvalerate) for the control of garden weevil on grapevines. This permit expires on 30 June 2007.

RESTISTANCE MANAGEMENT GUIDELINES

The CropLife resistance management strategy for Grey Mould (Bunch Rot) has been revised and is now much clearer.

EXPORT MARKET MRLs

The fungicide Domark 40ME which contains the active constituent tetraconazole was registered for use on grapevines by the APVMA in 2006. The APVMA proposed MRL is 0.5 mg/kg. However, this has not been gazetted in the Australia New Zealand Food Standards Code. Therefore, until this is gazetted no detectable residue of tetraconazole is allowed in Australian wine.

Other agrochemical issues

OTHER PRODUCTS

APVMA 53696

Hammer herbicide has been granted registration by the APVMA for the control of unwanted suckers (water shoots) arising from the main stem or trunk of grapevines. Hammer is distributed by Crop Care. It contains the active constituent carfentrazone-ethyl which is a Group G herbicide.

Surround does not require APVMA registration.

Due to the recent hot and dry season, the use of products such as Surround were being considered as a way of reducing leaf temperatures relative to ambient temperatures.
Surround as a protectant against sunburn and heat stress. is not required to be registered by the APVMA and there is no State or Territory legislation regulating its use. The registration process is governed by Commonwealth legislation. The agricultural chemical products that require registration encompasses all herbicides, insecticides, fungicides and growth regulators. It does not include products such as Surround because they do not fit the definition of an agricultural chemical product (For more information on this definition go to http://www.apvma.gov.au/registration/chemreg.shtml). Therefore, Surround can be used on grapevines despite the fact that grapevines do not appear on the label. Given the nature of the product, residues might be present at harvest, especially in the case of late season applications. We do not know if this will have any impact on the winemaking process and final wine quality. It is advised that you contact your winery or grape purchaser prior to application of this product.

CHEMICAL REVIEWS

Carbaryl
The final APVMA review has proposed that grapes be removed from the label of products currently containing carbaryl. The only use remaining for carbaryl on grapevines is for control of cutworms by application to the vine base (i.e. butt spray only).

Carbaryl is currently registered for use in viticulture against grape leaf blister mite, grapevine hawk moth, grapevine moth, LBAM, cutworm, mealybug and scale.

Methomyl
After a review by the APVMA, methomyl (Electra, Marlin, Lannate and Nudrin) is no longer registered for use on horticultural crops grown in protected cropping situations (glasshouse, greenhouse, shade houses etc.)

Carbendazim
The APVMA has announced a review of carbendazim is to take place for the same reason that benomyl was reviewed i.e. the potential to cause impairment of reproduction and development in laboratory rats may be relevant to human exposure.

AWRI launches Online Image Collection

14 March 2007 >

On 14 March, The Australian Wine Research Institute launched its online image collection. The collection is a searchable database of downloadable industry images, available from the AWRI website, in a variety of formats.

Access to these industry images has been made possible through the collaboration with professionals working within the industry. The project is funded by Australias grapegrowers and winemakers through their investment body, the Grape and Wine Research and Development Corporation, with matching funding from the Australian government. Users of this facility will contribute to the ongoing costs to maintain and expand the collection.

AWRIs Group Manager Communication and Information Services, Rae Blair, said The collection of images, some of which are nearly 60 years old, range from wine microorganisms to grape harvesting technology, and will be a useful resource for students, academics, researchers and industry members.

Rae Blair acknowledged the valuable contribution of slides and photographs by Dr Peter May (formerly CSIRO), Dr Bryce Rankine (formerly AWRI) and Dr Bryan Coombe (formerly University of Adelaide), These three gentlemen were committed to this project from the start, she said They were determined that these images not be lost to industry members and researchers. They contributed enormous hours to catalogue the images that they had gathered over the years during their careers.

The images supplied by these esteemed researchers are supplemented with the AWRIs own images collected since 1955. Ongoing contributions from CSIRO, as well as other organisations and individuals, will continue to expand the collection, maintaining value for users into the future.

A collection of more than 3,000 images is currently accessible via the AWRI website: http://www.awri.com.au

Application to become a Registered User can be made via the AWRI website. Registered Users can search and download from the database, and will find image files suitable for all graphics purposes.

Wine industry benefits from $0.5 m state government grant

14 February 2007 >

The Australian Wine Research Institute was delighted to announce its application to the South Australian state governments Premiers Science Research Fund was successful. The AWRI, which submitted the application on behalf of the Wine Innovation Cluster, will be awarded a $533,745 grant over three years to significantly develop its yeast research program.

Wine yeast does not just act as a fermenting agent in wine production; it plays a critical role in creating the flavour and aroma of wine, and a choice of wine yeast strains allows winemakers to predictably create wine with desirable sensory properties for specific target markets.

Managing Director, Professor Sakkie Pretorius, said the grant will enable us to purchase a new set of four bioreactors and a high-throughput fermentation instrument, required to develop new yeast strains. He said, This grant will boost our research program and allow the AWRI and its collaborators to rapidly and simultaneously characterise new yeast strains.

AWRI Business Development Manager, Dr Dan Johnson, said This grant will enable AWRI to create a fully-integrated discovery platform for the development of novel wine yeast strains. AWRI has a good track record in this area, and will now be able to generate many more leads for downstream development. He said the grant was also a reflection of the capability of the Wine Innovation Cluster to work across the grape and wine value chain and produce meaningful outputs for industry.

Specific targets of the AWRI yeast research program are to produce yeast strains that: (i) produce lower alcohol wine, (ii) extract/produce more flavour and aroma compounds and (iii) can complete ferments under significant environmental stress.
