Australian Wine Researchers First to Crack the Code

8 October 2008 >

In a world first, scientists at The Australian Wine Research Institute have cracked the genetic code of a wine yeast.

The breakthrough paves the way for development of improved wine yeast a key ingredient in winemaking.

“Availability of improved wine yeast will put winemakers in a stronger position to control fermentation and develop wines with the right quality, character and flavour” said Dr Anthony Borneman, a Senior Research Scientist at the AWRI.

“We’ve laid important groundwork for further sequencing and comparative analysis of other wine yeast strains.”

“We have made a significant breakthrough in understanding wine yeast,” said Dr Paul Chambers, Research Manager of AWRIs Biosciences team. “We will soon know where to look to find out why some wine yeasts can be troublesome and we will be better placed to improve and tailor them for production of particular wines for target markets.”

Using the latest technologies available through the Australian Genome Research Facility, the AWRIs sequencing project took about six months to complete. This is quite amazing in light of the fact that just over ten years ago, the first yeast strain to be sequenced took 70 laboratories, 10 years and cost millions of dollars.

“Today, we are unlocking the potential of yeast for winemakers, using genes to our advantage, without resorting to genetic engineering,” said AWRI Managing Director, Professor Sakkie Pretorius.

“By understanding the biology of yeast and the chemistry of wine we can use science to give the Australian wine sector an opportunity to innovate and maximise its market potential.”

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.

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/

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.

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.
