Common Insect Pests And Diseases On Fruit Trees In The Home Garden, Harald Hoffmann, Glynn Ward, Stewart Learmonth, Peter Wood

Bulletins 4000 -

Home gardeners frequently see insect pests and diseases affecting their fruit trees. Usually they would have seen them in previous seasons, so the pests or diseases look familiar. However, there are occasions, when an unusual pest (not native to Western Australia) can occur. These exotic pests are a concern for the farming community, as they could threaten the agricultural and horticultural industries and increase the price of production and the cost to the consumer.

This bulletin describes the most common insect pests and diseases on fruit trees in home gardens.

Managing Blackleg : A Grower's Guide To Minimising Risk From Blackleg Disease Of Canola In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Blackleg is spread primarily by wind, with the heaviest spore fall out normally occurring within 500 metres of any canola residue. Each year canola residue continues to produce blackleg spores at a diminishing rate until the stubble has completely broken down (see Diagram 2). In WA this breakdown could take up to 4 years, and so the recommendations are for long rotations.

The blackleg fungus can attack all the aerial parts of the plant. While leaf infection is the most obvious symptom, high levels of leaf infections do not necessarily indicate that major losses will occur from blackleg. It is …

Effects Of Pre-Milking Teat Sanitation On The Quality Of Raw Milk, Laurie Depiazzi, Ian Bell

Bulletins 4000 -

The effect of Quartermate pre-milking teat sanitation on milk quality was investigated in twelve dairy herds over a period of eight weeks. Pre-milking teat sanitation was carried out on all cows for six weeks on each of six farms and mesophile and thermophile bacteria counts of raw milks were compared before the milk line (“cluster” samples), and at various points within milking plants. Rates of mastitis, vat milk iodide levels and specific bacteria were also monitored.

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.

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 …

Western Australia’s horticulture industry is one of the State’s growing success stories, from mangoes at Kununurra to cherries at Mt Barker. The prospects are bright, especially in export markets where ‘clean and green’ produce from Western Australia is truly valued.

This book is designed to provide an accurate but readable account of the fight against fruit fly, incorporating all the …

Weed Plan For Western Australia, State Weed Plan Steering Group, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

One of the most significant environmental challenges facing Western Australia is the minimisation of the impact of weeds. In the relatively short history of this State since European settlement, some 1155 exotic plant species have established as weeds in our diverse and generally fragile ecosystems. While development for agriculture, mining, transport and housing must by its nature result in some change to the State’s flora, the introduction of weedy plant species has caused serious impacts which cause great concern.

Weeds now pose a serious threat to many of the State’s ecosystems, and impose high annual costs on agricultural industries. Weeds …

Paterson's Curse Management Handbook, Amelia Mclarty, Errol Kruger, Peter Stubbs, John Peirce, Chris Hawkins, Paul Wilson, Simon Merewether

Bulletins 4000 -

Paterson’s curse (Echium plantagineum) is one of the most damaging weeds to the Australian meat and wool industries. It infests an estimated 33 million hectares in southern Australia, at an annual cost to the sheep industry of $250 million in lost pasture productivity, control costs and wool contamination. In WA, it is found on about 5000 agricultural properties infesting some 500,000 ha. It is an extremely invasive weed, that reduces pasture productivity and stock carrying capacity by competing with and excluding more beneficial pasture species. The weed is also toxic to stock. It is important to implement control measures on …
