Compost extract: a new paradigm for disease management in sustainable horticulture. There is significant legislative and consumer pressure worldwide to reduce the amount of pesticide applied to food crops. Compost extract is a watery extract of mature compost that when applied to a crop canopy allows simultaneous suppression of a broad range of plant diseases while maintaining biodiversity in an agricultural ecosystem.

There is significant legislative and consumer pressure worldwide to reduce the amount of pesticide applied to food crops. Compost extract is a watery extract of mature compost that when applied to a crop canopy allows simultaneous suppression of a broad range of plant diseases while maintaining biodiversity in an agricultural ecosystem. This technology represents a paradigm shift from the monoculture approach of single-target fungicides or biological control agents. Scientific evaluation has been hampered by a lack of standard production techniques. Our aim is to identify and characterise compost extract technology that produces known and consistently high levels of effectiveness and safety.Read moreRead less
Biological control of grapevine scales. Wine grapes can be grown with a minimum of pesticide and fungicide applications in some regions, but biological control is still required to maintain populations of major pests. This project is concerned with grapevine and frosted scales, which are common pests of grapevines. The distribution and identity of different grapevine scales, and their main parasitoids, in the various grape growing regions of Australia will be determined by initial surveys. Exper ....Biological control of grapevine scales. Wine grapes can be grown with a minimum of pesticide and fungicide applications in some regions, but biological control is still required to maintain populations of major pests. This project is concerned with grapevine and frosted scales, which are common pests of grapevines. The distribution and identity of different grapevine scales, and their main parasitoids, in the various grape growing regions of Australia will be determined by initial surveys. Experiments and laboratory studies of the interaction of the various predators and parasitoids will be undertaken to develop a biological control program of the scales aimed at reducing pesticide input.Read moreRead less
Attract and reward: a novel approach to enhancing biological control of crop pests. Pests cause serious damage to Australia's agricultural crops. Current control relies heavily on synthetic pesticides. This project will develop novel products based on natural plant compounds to attract beneficial insects into crops where they will be supported with nectar, pollen and shelter to maximise their lifespan, reproduction, residency. This use of Australia's beneficial insect biodiversity will provide ....Attract and reward: a novel approach to enhancing biological control of crop pests. Pests cause serious damage to Australia's agricultural crops. Current control relies heavily on synthetic pesticides. This project will develop novel products based on natural plant compounds to attract beneficial insects into crops where they will be supported with nectar, pollen and shelter to maximise their lifespan, reproduction, residency. This use of Australia's beneficial insect biodiversity will provide novel pest control options to help transform the vegetable and grape industries. The work will reduce reliance on conventional pesticides; thereby contributing towards Australia's environmental sustainability and providing healthier foodstuffs. Read moreRead less
Control of foliar diseases in horticulture using milk components: widening applicability through understanding mechanisms. Fungal diseases, such as powdery mildew and botrytis grey mould, have the potential to cause considerable losses in horticultural crops. Chemical fungicides, some of which are broad-spectrum biocides potentially harmful to human health, are applied routinely in disease management. Milk and whey, which can damage powdery mildew fungi, offer alternatives to conventional fungic ....Control of foliar diseases in horticulture using milk components: widening applicability through understanding mechanisms. Fungal diseases, such as powdery mildew and botrytis grey mould, have the potential to cause considerable losses in horticultural crops. Chemical fungicides, some of which are broad-spectrum biocides potentially harmful to human health, are applied routinely in disease management. Milk and whey, which can damage powdery mildew fungi, offer alternatives to conventional fungicides. Identification of the components of milk which damage fungi, and their mechanisms of activity, will facilitate the development of environmentally sustainable strategies for management of fungal diseases in Australian horticulture. This will have particular benefits for personnel who regularly apply fungicides in glasshouses.Read moreRead less
Beneficial arthropods in Coonawarra vineyards and sustainable grape production. Many species of pest and beneficial arthropods live in vines and groundcover of vineyards. Vignerons often devote considerable effort to sustain populations of what they believe to be beneficial arthropods. However, the types of natural enemies and techniques to enhance their effectiveness are poorly known. This project aims to identify and quantify the role of natural enemies in controlling the main pest in Coonawar ....Beneficial arthropods in Coonawarra vineyards and sustainable grape production. Many species of pest and beneficial arthropods live in vines and groundcover of vineyards. Vignerons often devote considerable effort to sustain populations of what they believe to be beneficial arthropods. However, the types of natural enemies and techniques to enhance their effectiveness are poorly known. This project aims to identify and quantify the role of natural enemies in controlling the main pest in Coonawarra vineyards, identify their food and shelter requirements, and improve management practices and other techniques to optimise populations of beneficial species. The significance of this project is that it will enable the promotion of insecticide-free production of winegrapes in the Coonawarra.Read moreRead less
