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
Pacific Labour and Australian Horticulture. This 18-month research project will investigate the costs and benefits of increasing labour mobility between the Pacific and Australia, including the feasibility of a seasonal labour program to employ agricultural workers from Pacific Island nations in the Swan Hill/Mildura region during periods of peak labour demand. It will forge a ground-breaking collaboration between an international development agency and local government to investigate how such a ....Pacific Labour and Australian Horticulture. This 18-month research project will investigate the costs and benefits of increasing labour mobility between the Pacific and Australia, including the feasibility of a seasonal labour program to employ agricultural workers from Pacific Island nations in the Swan Hill/Mildura region during periods of peak labour demand. It will forge a ground-breaking collaboration between an international development agency and local government to investigate how such a scheme might contribute simultaneously to economic and social development in Pacific Island nations (through remittances and skills transfers) and in regional Australia (by improving the labour supply to key horticultural industries).Read moreRead less
Improving water use efficiency of grapevine production in the Great Western region using effluent water and soil amelioration practices. Irrigation of vineyards with municipal wastewater is a desirable option for the viticulturists of the Great Western region of Victoria, but only if vineyard soil structure is not adversely affected. This project will (1) study the impact of dissolved chemicals in the waste water on the structure of the local sandy soils; (2) model the data to enhance understand ....Improving water use efficiency of grapevine production in the Great Western region using effluent water and soil amelioration practices. Irrigation of vineyards with municipal wastewater is a desirable option for the viticulturists of the Great Western region of Victoria, but only if vineyard soil structure is not adversely affected. This project will (1) study the impact of dissolved chemicals in the waste water on the structure of the local sandy soils; (2) model the data to enhance understanding of the key chemical and physical mechanisms controlling grey water impact in heterogeneous environments. The resulting predictive tools will have direct application in the Great Western region's vineyards, and for irrigation of grey water in vineyards across Ausralia.Read moreRead less
