feathertop rhodes grass is a highly aggressive weed that, despite being a focus of several research efforts, is continuing to increase in incidence and severity in northern farming systems. the recent confirmation of resistance to glyphosate also highlights the need to manage the weed with an integrated systems approach. this proposal builds on work in daq00105, us00084, and nga00004 that have investigated various strategies for managing feathertop rhodes grass in the summer/winter cropping areas of the northern region. to facilitate improved management of feathertop rhodes grass in queensland and northern nsw, a communication and extension campaign is required. the procurement will update the current feathertop rhodes grass integrated weed management iwm publication for winter/summer cropping areas by incorporating recent research results and will be used as the focus of a targeted extension campaign. in the winter cropping areas of southern nsw, research is required to develop a locally adapted feathertop rhodes grass iwm plan for the prevailing farming system. this should be based on the existing iwm plan but will need to address: 1. differences in the value of residual herbicides based on the presence of sandy, acidic, low oc soils, lower and winter dominant rainfall and crop choice taking into account possible product registration opportunities 2. differences in the effectiveness of cultivation based on soil type 3. use of site-specific weed management 4. opportunities for management in the pasture phase e.g. chemical options and with grazing as a first step in a double knock and 5. the impact of livestock on both spread and/or control of the weed e.g. livestock field preference and feathertop rhodes grass regrowth. extension of this work to growers in southern nsw is a key component of this procurement.
supply of production of high value, human consumption pulses in australia is dominated by lentil and chickpea, and is concentrated on the more fertile soils in the medium rainfall areas of the southern and northern regions. due to the farming system benefits of imposing a double break and the high prices in recent years, there is much interest in expanding lentil and chickpea production onto soils with a number of constraints acidity, nutrient toxicities and deficiencies, poor structure and into other rainfall zones. it is critical that new pulses be developed and managed such that the crop life-cycle fits within the constraints of availability of soil water, frost and heat stresses and flowering and pod-set occur in the optimum window for different agroecological zones. as time to flowering and pod-set are so critical in these crops, understanding and improving them in existing production regions and where they have not been optimised yet is one of the most critical elements that can contribute to their adoption and deliver potential step changes in yield and profit. the national pulse phenology investment proposed will utilise common genetic resources across existing and potential pulse expansion regions of australia to expedite delivery of data, tools and knowledge which can inform crop breeding. it will leverage international r&d activities, and new synergies provided by recent developments in understanding of genome synteny and conserved pathways in this group of crops to deliver on investment outputs.
recent incursion of the barley disease ramularia has not been fully delimited around the areas of confirmed occurrence. as this disease can spread through infected seed, growers in these regions will need information on the relative risk of saving seed for planting the following year. other regions that currently have had no positive recordings will need to be surveyed to ensure that these areas are currently free from ramularia. ramularia in the northern hemisphere and new zealand has recently increased in pathogen aggressiveness, decreased in fungicide sensitivity and caused epidemics in germany. determining the occurrence of ramularia across the australian grain belt will inform the level of disease management options required including seed hygiene, fungicide and pre-breeding investments.
falling number fn is a global industry standard used to quantify detrimental pre-harvest sprouting phs in wheat, as early release from seed dormancy leads to significant effects on end product quality. however, a low falling number can also be caused by the trait of late maturity alpha-amylase lma, with some wheats having a genetic predisposition to accumulate low levels of starch digesting enzymes during grain filling in the absence of sprouting. lma susceptibility is currently a classification criterion for milling wheat in australia. due to the cost involved in the current lma susceptibility screen, it is currently employed at a late phase in the breeding pathway of australian wheat breeding programs, which significantly restricts genetic gains for yield and other traits in australian wheat varieties.
