Development Of Redglobe Table Grapes For Export, Ian Cameron

Journal of the Department of Agriculture, Western Australia, Series 4

Exports wereonce a major outlet for the Western Australian table grape industry.

Over the last 20 years however, exports have fallen from 500 to 00 tonnes per year, despite an increase in the area planted to table grapes and an increase on overseas demand for our produce.

By 1993 less than 3 per cent of the table grapes produced in the State were exported.

The introduction of Redglobe, a new table grape varietyy from California, is expected to increase the export of table grapes from Western Australia to 1000t by 1997, when the variety will represent 90 per cent of …

Journal of the Department of Agriculture, Western Australia, Series 4

The quantity and style of wine consumed in Australia has changed dramatically since the 960s.

Besides the increase in consumption from 9 to 19.9 litres per head in the past 10 years, the major changes have been the greater importance of table wine, particularily white table wine, and the more exacting standards set by consumers and wine producers.

Powdery Mildew Or Oidium Of Grapes, H L. Harvey

Journal of the Department of Agriculture, Western Australia, Series 4

POWDERY mildew or oidium, is a disease which is always present to a greater or lesser extent in grapevines in Western Australia.

In seasons favourable for its development it stunts the growth of shoots and leaves and may seriously reduce fruit yields and quality.

Most of our commonly-grown varieties are quite susceptible to the disease, but for the reason that currants are the most extensively grown variety, the overall losses are greatest in this variety.
