Rural Water Use Efficiency 4

The purpose of this proposal is to detail the proposed service provision project to be undertaken by staff from the Department of Employment, Economic Development and Innovation (DEEDI – formerly DPI&F) to the Flower Association of Queensland Inc (FAQI). FAQI to successfully fulfil FAQI’s requirements under the Rural Water Use Efficiency 4 project.

Reducing flesh bruising and skin spotting in Hass avocado

Up to 80% of avocados on the retail shelf have defects in the flesh which reduces consumer satisfaction. Flesh bruising is the single most important contributor. Avocados also develop skin spotting during harvesting and packing which can reduce domestic and international customer confidence. This project will identify where bruising occurs, develop decision aid tools to help industry reduce flesh bruising in ripe fruit, and understand the commercial impacts of skin spotting. The project will include a PhD student with stipend coming from an international scholarship and in kind support from the University of Queensland.

Scoping study: management options for mealybug in persimmon

Mealybug contamination is a major hurdle for access to profitable export markets. This project seeks to review worldwide research into management options for mealybug in persimmon and other cropping systems.

Controlling plant and fruit diseases in strawberry fields

Grey mould, powdery mildew and stem-end rot are major diseases affecting the strawberry industry. Some of the chemicals used are ineffective under wet weather, have limits to the number of applications allowed in a season or may become ineffective in the long-term because of the development of resistance in the fungi. We will assess the effectiveness of the chemicals currently used by the strawberry industry and whether the fruit rot fungi are resistant to these fungicides. We will screen other chemicals that are used to control these diseases in related crops. We will also evaluate new chemicals in collaboration with the crop protectant industry. We will also undertake similar work to control nematodes in strawberry fields.

Northern Integrated Disease Management

This project has the overall aim of reducing the impacts of diseases of winter cereals, pulses, sunflower sorghum and nematodes on farming systems in the GRDC northern region. Integrated disease management packages which involve combinations of resistance, targeted fungicide applications, cultural practices such as rotations, and disease modelling will be developed and extended to clients. Structured surveillance activities will enable the monitoring of the distribution and importance of diseases and pathotypes, the early detection of significant outbreaks of endemic and exotic diseases, and a rapid and appropriate response to these outbreaks.

CRC Field Analysis

Provide diagnostic support for plant pathology projects, including the maintenance and preservation of reference specimens.

Value chain technical development

Short-term research projects on insect pest management in processed food.

DAQ00129 Improving the Integration of Legumes in Grain and Sugarcane Farming Systems in Southern Queensland

The farming systems and agribusinesses of the inland Burnett and southern coastal cropping regions of Queensland are becoming increasingly interlinked as grain legume crops, a key component of dryland cropping systems, become more firmly entrenched in the coastal sugarcane cropping areas. Soybeans, peanuts and possibly winter cereals like barley have a real and demonstrated role in sugarcane rotations, and assistance with the integration of those crops into viable and sustainable cropping systems with sugarcane will be critical to the futuer development of these industries.

ACIAR Improving Postrainy Sorghum Varieties Grain and Fodder in India

Sorghum grown in India in the post-rainy season (Rabi) relies on residual soil moisture, and the crop is commonly exposed to terminal drought stress. But there is a ready market for its high-quality grain and stover (used as fodder on dairy farms). Steps to improve productivity while maintaining quality offer an attractive opportunity for sorghum farmers to improve their incomes. Genetically improving the efficiency of using stored soil moisture is a prime target to maximise grain/stover production and quality of Rabi sorghum. This project aims to achieve this through the application of DNA sequences known as quantitative trait loci (QTLs). The project scientists will introduce marker-assisted introgression of stay-green QTLs into sorghum lines, enhancing both the quality and the quantity of grain/stover of postrainy sorghum. They will also use modelling to identify the key physiological traits involved in a higher, more stable yield across water-limited environments of India and Australia, and the key stay-green QTLs contributing to these traits. The publicly available QTL isolines lines developed in this project will be the basis of new varieties to be bred in a subsequent phase.

CRC27012 A National Diagnostic Database for Emergency Plant Pests

Development of a national diagnostic database for Emergency Plant Pests which will be web-accessible.

Remote Sensing - based precision agriculture tool for the sugar industry

The project will produce practical and relevant benchmarks, protocols and recommendations for the adoption of remote sensing technologies for improved in season management and therefore production within the Australian sugar cane industry.

CRC50151 Resistance Management

Develop nationally agreed, standard methods for insect sample collection, resistance testing, and data management as a basis for a statistically robust and informative national resistance monitoring program.

CRC50150 Targeting mechanisms of phosphine resistance in stored grain pests

The objectives of this projects are: 1)To ensure the identification of genomic DNA markers for phosphine resistance in Rhyzopertha dominica and Tribolium castaneum; 2) To determine gene function of identified phosphine resistance genes in Rhyzopertha dominica and Tribolium castaneum; and 3) Predict future problems by characterising international resistances using our genes as a starting point to determine strong resistance can get by determining similarities with Australia.
