The African black beetle, Heteronychus arator, is an important pest of horticultural crops, ornamentals and pastures in Western Australia. They also attack lawns and are commonly referred to as the black lawn beetle. This beetle was first recorded in Australia during the 1920s and originates from southern Africa where it is a major establishment pest of maize.

The tastebuds, health concerns and environmental conscience of affluent consumers are demanding more organically grown food than producers worldwide can supply. Growing consumer concerns about the effects of synthetic chemical pesticides and fertilisers on human health and the environment have boosted world trade in organic products by a rate of about 20-30 per cent a year for the past 10 years. World trade was estimated to be worth $US 21.6 billion in 2000 and is expected to reach US$100 billion by the year 2006.
The Australian market for organic products alone is valued at $200-$250 million - with exports estimated …

The Scott Coastal Plain has significant attributes that make it an area of State and regional significance for agricultural production. The climate, availability of good quality groundwater for irrigation, and large lot sizes provide opportunities for mechanised horticultural production which other parts of the State may not have.
An estimate of the area that could be used for each agricultural land use has been developed, at a broad study area level. The figures presented in this report show that diversified production combining tree plantation and/or irrigation (cropping or hay/silage) with grazing enterprises provides for potential increases in gross margins and …

Eutrophication is essentially the nutrient enrichment of waterways leading to algal growth. It must be controlled to maintain sustainable agricultural systems and the main mechanisms of control are stabilising catchment processes and reducing nutrient output.
Eutrophication can be defined as 'the nutrient enrichment of waters which results in the stimulation of an array of symptomatic changes, among which increased production of algae and macrophytes, deterioration of water quality and other symptomatic changes, are found to be undesirable and interfere with water uses' (OECD 1982). The word eutrophic is a Greek word that means 'well fed'. The food referred to is …
