Skeleton Weed In Western Australia, Pocket Guide, State Skeleton Weed Committee, Department Of Agriculture And Food, Western Australia, Agriculture Protection Board

Bulletins 4000 -

The Skeleton Weed Program is a coordinated approach to eradicating skeleton weed in Western Australia. It is run jointly by the State Skeleton Weed Committee, the Department of Agriculture and the Agriculture Protection Board. It is funded through the skeleton weed levy collected from grain growers each harvest, and pooled in the Skeleton Weed Eradication Trust Fund.

Skeleton weed is targeted as a declared plant as it can drastically reduce crop yields (more than 1 tonne/ha in cereals) by competing for moisture and nutrients, mainly nitrogen. Its wiry stems impede headers and the sticky latex they contain cause machinery to …

Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Phytophthora root rot is the most common soil borne disease causing plant death in native cut flower production. It is also a pathogen of exotic cutflower crops such as rose, lily, carnation, proteas and gerbera. The fungus, Phytophthora cinnamomi, the cause of jarrah dieback is the pathogen that first comes to mind when Phytophthora is mentioned. This has one of the widest host ranges of all Phytophthora species, particularly amongst native Australia species. P.nicotianae also has a wide host range, infecting a wide range of exotic, as well as Australian native flower crops. There are also a number of …

Botrytis In Wine Grapes In Western Australia, Diana Fisher, Colin Gordon, Peter Wood

Bulletins 4000 -

Botrytis, causal agent Botrytis cinerea, is a fungal disease of grapevines that is commonly referred to as Botrytis bunch rot or grey mould. Botrytis is most prevalent where warm, wet conditions are frequent, but symptoms can occur in cool, wet weather and high humidity. All grape varieties are susceptible. Varieties most at risk are those with berries that are thin-skinned and/or have tight bunches.

Some white wine grape varieties infected with Botrytis may decay, in certain conditions to produce noble rot . Wine produced from these infected bunches produce unique aromatic characters with high residual sugar and are …
