Botrytis and Brett back on the NSW regional agenda

The first year results of a botrytis spray trial have been collated and the trial continues for a second year funded through the GWRDC Greater-NSW Regional Program 2013-14.

The GWRDC Regional Program is designed to encourage regional adoption and adaption of research findings and is offered to all grape-growing regions.  The Greater-NSW Regional Program covers 15 GIs across NSW and Canberra (excluding the Riverina) and is managed by the NSW Wine Industry Association and NSW Department of Primary Industries Development Officer Jason Cappello.

‘It’s definitely one of the most diverse zones and  it is a unique challenge to find and fund Regional Program activities that reflect the different needs and interests of these wine regions’, Mr Cappello said.

‘We do work hard to identify the different interests and we put forward trials and research topics for funding that the industry sees as being useful.  I know that discussion of projects and research issues that might be included in the 2014-15 Regional Program is already a key focus for the NSW Wine Industry Association’s Research and Development Committee.

‘We had some really positive results from last year’s program, so we’re looking forward to sharing the knowledge gained from that first year’.

The Botrytis Management Trial is testing the application and results of a conventional spray program against Trichoderma mixtures (an organic spray of fungicidal potassium soap) and a control treatment of no botryticides.

The trial is being conducted at Pyramid Hill vineyard, in the Upper Hunter.

NSW Wine Industry Association consultant Richard Hilder, who helped conduct the trial, reported that early results showed interesting outcomes for the organic products.

Also making a return to the region were the Winery Management Workshops, which presented the latest research findings and advice on identifying sources of Brettanomyces, as well as managing tannin and acid in wine.

‘We had some fantastic feedback from these workshops, so we plan to extend them out to other Greater-NSW regions and perhaps look at extending new industry research’, Mr Cappello said.
