Rapid pest/disease surveillance and monitoring using smart technology for crop protection and market access
This project will also establish a network of smart traps in the WA grainbelt which will utilise both rapid molecular techniques such as LAMP and standard PCR assays in conjunction with traditional morphology techniques for the identification of targeted endemic pests and diseases.
The Smart Trap array will be linked to decision support tools and delivered by PestFax and direct email platforms that will provide rapid and accurate information to growers to assist them to make management decisions on disease and pest control during the growing season.
In addition, the Smart Trap array could provide real time surveillance for incursions of exotic pests and diseases allowing a rapid response to incursions.

Gravel soils (two components)
New approaches to quantifying the properties of gravel soils and for sampling inverted soils to improve crop management
New approaches are required to improve fertiliser and lime applications for gravel and inverted soils in the Western region, however, knowledge gaps are constraining future accurate recommendations.
A low-cost approach to assessing gravel soil properties is required to improve recommendations for these soils; machine vision (automated digital image analysis) is a prospective method but it has not been developed yet.
Similarly, a low-cost, practical approach to sampling inverted soils is required but there is limited understanding of which soil properties are most important and how crop roots are responding to a changed spatial and temporal supply of nutrients.
The target outcome of this project is an improved fertiliser recommendation whereby commercially recommended models including gravel content will provide capacity to use better information about gravel.

Overcoming constraints to profitable cropping on forest gravel soils in the Western region
This project forms a vital component of a GRDC project (of the same name).
The aim of this project is to provide growers and advisors with knowledge that will improve the management of crops grown on gravel soils.
Current knowledge will be synthesised in a review of literature and grower and advisor experience to identify knowledge gaps.
Current knowledge on the spatial extent of gravel soils in the Western region will also be reassessed with the intent of identifying different gravel soil types that require different management.
The hydrology of gravel soils and their mineralogy will also be assessed with an emphasis on nutrient availability to crops.
All of this work will be used to guide a program of glasshouse and field experiments which will address key knowledge gaps and provide an evidence-base for extension.
More specifically, this Royalties for Regions contribution will be used for profile characterisation of gravel soil types, an agronomic transect study that will identify factors limiting yield on forest gravel soil and phosphorus isotope analysis to quantify the relative contribution of soil and fertiliser phosphorus on gravel soils.

Epidemiological, genetic and farming system factors impacting on the development of powdery mildew in WA wheat production
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is an important disease of bread wheat (Triticum aestivum L.).
Little is known about powdery mildew management in WA and the extensive cultivation of susceptible wheat varieties over the years combined with favourable environmental factors has seen the pathogen and its economic importance become more evident in recent years.
The aim of this project is to evaluate aspects of the epidemiology of this pathogen, survey for differences in virulence of the pathogen, relative responses of varieties (particularly in relation to growth stage and environment) and interactions with nutrient and soil type management.
The project will provide information and extension tools to aid growers in choosing appropriate varieties for regional disease threat, understand what farming system decisions, particularly plant nutrition, impact on disease development and relative crop vulnerability and potentially reduce reliance, or provide improved guidance of fungicide intervention.

Screening wheat germplasm and identifying the genetic control for rapid emergence and rate of grain fill with less water
Yield maintenance under water limitation is an important objective for crop improvement in WA, however crops in the state's Mediterranean-type environments can be exposed to water limitation at both ends of the growing season, and adaptations that improve crop resilience at the beginning of the growing season will not necessarily be effective at the end and vice versa.
Identifying the number of genes and the genetic control of traits that respond to varying soil moisture, either at the beginning or the end of the growing season, provides much needed knowledge and resources for developing new improved commercial wheat varieties.
The germplasm identified and the associated DNA markers linked to genes controlling desirable trait expression will be delivered to wheat breeding companies so they have the tools and resources to breed new commercial varieties with higher probability of grain yields and stability under variable soil moisture conditions at both ends of the growing season.

SoilsWest Alliance
This project is a foundational step in developing a SoilsWest Alliance between University of Western Australia and DPIRD in the first instance with option to transfer to the new grains research entity when it is established.
This project and a future SoilsWest Alliance will be substantially focused on the productivity and profitability of the Australian grains industry, but from time to time may address broader aspects affecting the agricultural sector.
The partnership will combine substantial complementary scientific and research capabilities, research and industry networks and infrastructure and technology for the long-term development of science capability in WA, and to develop and deliver strategic research projects supporting the WA grains industry in particular, but also contributing nationally to the Australian grains industry through innovative soil research.

Frost proofing – management and reduction of frost damage in WA
Royalties for Regions funds will support a number of staff appointments within the suite of projects contributing to the National Frost Initiative Management program.
One of these is an early career scientist whose work will enable grain growers to refine crop management strategies to optimise plant resilience, yields and quality – and ultimately increase profitability.
In the National Frost Initiative, Dr Dion Nicol aims to identify gaps in the existing knowledge of a plant’s physiological response to minor frost damage, such as damage to its vascular system and photosynthetic capacity, and how plants recover.
His work will span plant physiology and nutrition and will be integrated into ongoing farming systems research.
