It was proposed that DRB be isolated and evaluated against ARG. Successful organisms were then to be applied in high numbers and assessed in field situations... Until the mode of action of these bacteria is clearly defined and/or a rapid isolation and assessment protocol (perhaps with the aid of gene technology) identified, this project needs to be shelved... It was proposed that DRB be isolated and evaluated for annual ryegrass - with the aim of inhibiting seed set and subsequent annual ryegrass toxicity reduction...

It is well established that genotype has a large influence on the development pattern of wheat but little is known about how development and growth are related... There is some experimental evidence that vigour (or early growth) is positively related to developmental rate but this was obtained in the field and did not take root growth into account... The aim of the project is to explore this relationship by carefully measuring whole-plant growth of genotypes varying in vernalisation responsiveness...

Natural seed coating wins Eureka Prize.. Australian graingrowers may soon have a double-barrel weapon in the fight against fungal diseases - a natural seed coating that protects a developing plant against fungal disease and boosts growth at the same time... Professor Franco says his team knew that actinobacteria could produce a range of chemical structures, including antibiotics...

Researchers in different cropping regions are studying how to lift nutrient use efficiency by manipulating a crop's root systems.. In the south and west, Dr Manny Delhaize from CSIRO Agriculture has discovered that root hairs play a key role in improving the phosphorus use efficiency of wheat in acid soils... University of New England Associate Professor Chris Guppy is using 3-D computer-aided images (above) of cereal root systems supplied with phosphorus to identify whether they have the capacity to respond to the deep nutrient placement strategies being developed in the northern grains region...

A survey of 142 Australian agronomists found that 20 per cent recommend the use of plant growth regulators in crop management of wheat, mainly due to improved lodging resistance followed by height reduction and improved yield... The paper provides a brief overview of current plant growth regulators (PGRs) and reports on selected results of a survey of Australian agronomist's use of PGRs in wheat production... When agronomists participating in the survey were asked to explain the benefits that come from using PGRs in wheat, effects on lodging and the related theme of height reduction were frequently reported (Figure 1)...
