Nematode that attack plants cause $120 billion of crop losses worldwide. Chemicals used for their control are being phased out because of environmental concerns, and natural resistance is limited. The aim of this project is to use Australian IP to develop a new form of resistance to nematodes based on knowledge of the host-pathogen interactions. A successful outcome could contribute an additional 5-20% increase in crop yields (depending on the crop) through inherent resistance of crops to nematode pests. This would benefit rural communities and the national economy, and could also generate international royalties.Read moreRead less

The Australian economy relies heavily on agricultural production. The outcomes of the projects supported by these growth facilities will be of economic benefit to the nation by producing new knowledge of plant-insect and plant-pathogen interactions, how plants acquire essential nutrients, and how they respond to environmental stress. The research outcomes will benefit the environment by increasing legume production and so reducing land degradation and risk of nitrate contamination of waterways and lowering the environmental risk from agrochemicals by developing safer strategies for control of pests and diseases. In addition, a number of projects that will benefit from the glasshouse facilities aim to produce healthier and safer foods.Read moreRead less

Genome wide physical mapping is the centrepiece of current genomics research in virtually all plant and animal species. The proposal seeks to champion the development of Prunus dulcis (Rosaceae) as a model perennial species towards parity with other plant model systems for gene discovery and validation. The Rosaceae represents a rich repository of genes of relevance to perenniality, adaptation, sustainable agriculture, health and nutrition and the bioindustries. Ultimately, comparative genomics across the family will advance molecular eco-genetics via dissection of traits determining adaptive response. Access to user-friendly molecular markers will also bring greater precision to breeding programmes. Read moreRead less
Development of a novel, non-chemical technique based on the EppoMNPV baculovirus for the control of the lightbrown apple moth. Lightbrown apple moth (LBAM) is a serious pest of many horticultural crops in Australia, costing the economy about $21 M pa. Methods for controlling LBAM have relied on the use of insecticides. However, the pest has developed resistance to a wide range of chemicals used against it.

Lightbrown apple moth (LBAM) is a serious pest of many horticultural crops in Australia, costing the economy about $21 M pa. Methods for controlling LBAM have relied on the use of insecticides. However, the pest has developed resistance to a wide range of chemicals used against it. This proposal aims to assess the potential of the EppoMNPV polyhedrosis virus as an alternative to insecticides for its control. Successful development of the virus will provide an environmentally benign alternative to insecticides that can be used to control LBAM in a range of different circumstances including broadacre and organic production.Read moreRead less
Coal-ash as a resource for sustainable soil-management in plant production systems. Acidification and salinisation are major causes of land degradation in Australia, costing $1-2 billion to combat. Farmers used 1.9M t of lime and 1.0M t of gypsum to manage their soils in 2000. Power stations annually produce 12M t of coal-ash that have functional characteristics of lime and gypsum and can potentially ameliorate degraded land. Presently only 43% of the ash is used and almost entirely for constr ....Coal-ash as a resource for sustainable soil-management in plant production systems.

Power stations annually produce 12M t of coal-ash that have functional characteristics of lime and gypsum and can potentially ameliorate degraded land. Presently only 43% of the ash is used and almost entirely for construction with the rest going into landfills. This project will determine the sustainable use of coal-ash to improve structure and nutritive properties of the soil and to raise crop yield across several sites in Australia.Read moreRead less
