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 …

Southern Weeds And Their Control, John Moore, Judy Wheeler

Nematodes In Western Australian Vineyards, Vivien Vanstone, Neil Lantzke

Bulletins 4000 -

Nematodes are worm-like microscopic animals that live in the soil. There are numerous soil-inhabiting nematode species, but not all are harmful to plants. Some nematodes are plant-parasitic, feeding on and damaging roots, including those of grapevine. Feeding activities of these nematodes reduce the vine’s ability to take up water and nutrients from the soil, leading to lack of vigour, symptoms of nutrient deficiency, wilting, lower yield, vine decline and, in severe cases, vine death. Nematode feeding sites can also lead to entry of other disease-causing organisms (e.g. fungi or bacteria), resulting in rapid vine decline.

Nematodes can survive in the …

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 …
