Development of sustainable management for Pimelea and pimelea poisoning

Toxic Pimelea species (desert riceflower) are naturally occurring species found throughout beef cattle regions of Queensland, New South Wales, South Australia and the Northern Territory. Three species of Pimelea (simplex, elongata, and trichostachya) are poisonous to livestock and potentially fatal to cattle, with serious economic consequences through the loss of production, stock deaths and the costs of agistment. A better understanding of the ecology of the plant/disease is required to develop best practice to manage Pimelea in cattle-producing areas. Development of a chemical assay for the toxin (simplexin) is a key component of the current research project enabling toxin levels to be related to stage of plant growth, environmental and climatic factors.

Test and develop sustainable and profitable grazing strategies to manage for rainfall variability

The Wambiana grazing trial started in 1997 to test and develop sustainable and profitable grazing strategies to manage for rainfall variability. It is important that this trial continue as the results are still relatively short-term relative to rainfall cycles and significant treatment changes are still occurring. This new proposal will maintain baseline treatments but will modify others based on trial learning’s to date. It builds on treatment differences and evidence collected over the last 12 years to deliver evidence-based guidelines and principles for sustainable and productive management. The trial also links to other projects modelling water quality, climate change, methane emissions and soil C sequestration on grazing lands.

Strategic banana tissue culture industry development and biosecurity act

Application and development of activities based on in vitro technologies delivering research, industry development and biosecurity activities to sustain and improve the Australian banana industry.

ACIAR Improving soil health in support of sustainable development in the Pacific

The proposed project focuses on developing research-based indicators that growers and extensionists can use to assess soil health status (including key chemical, physical and biological variables), as well as extension approaches to communicate soil health.

ACIAR Pacific Agribusiness Research for Development Initiative (PARDI)

PARDI provides a platform for stronger economic growth of Pacific island countries. The initiative aims to substantially improve the livelihoods of smallholder farmers in the Pacific. Benefit to Queensland includes: 1) looking at supply chain (value chain) innovations for tropical horticultural commodities in both Queensland and the South Pacific to maintain competitiveness. 2) undertaking research on a product called canarium nut which is grown in the Solomon Islands. It is a new potential high value speciality product (similar to macadamia) in which macadamia industry partners are participating. 3) involvement in specific targeted supply chain business improvement with industry partners.
