" Beneficial Microbes Program - progressing new microbial products for Australian grain production to commercialisation... Australian farmers are keen to reduce on-farm chemical inputs and replace them with biological alternatives... Research has shown that the soil biota can be manipulated for the benefit of crops through management practices, such as tillage, stubble retention/burning, crop/pasture sequencing and liming...

New fungicides to tackle Rhizoctonia.. Paul Bogacki (left) from SARDI and Jack Desbiolles from the University of South Australia, discuss the plot layout for the Rhizoctonia fungicide trial, which has included surface, seed and deep placement of the fungicide... Research results indicate the risk of Rhizoctonia damage will be reduced for: cereals following grass-free canola, pulses and pastures; crops with rapid early root growth down the soil profile - consider sowing early with soil disturbance below the seed, deep band nitrogen and new fungicide seed dressings; and registered fungicide seed dressings used in paddocks with low to moderate levels of Rhizoctonia..

Zones based on water use efficiency and variable rate inputs are helping Peter Kuhlmann remain viable on his low-rainfall property near Ceduna, South Australia... At the SPAA Expo in South Australia in February, Peter explained the farming practices he uses to collect and conserve the limited rainfall received by his property... One tool to help maximise crop water use and minimise water loss is stubble retention, using: no-till with knife points - tillage beneath the row is used to help reduce the root disease Rhizoctonia; presswheels; wider row spacing - less crop competiton and allows inter-row sowing to improve seedling establishment due to protection from wind; and early and dry sowing with good seed and nutrient placement...

The overall objective of this research program is to develop and deliver strategies for management of plant diseases of importance to SA grains industries... The increased frequency of cereals and greater adoption of susceptible cultivars is creating an opportunity for cereal cyst nematode (CCN) to re-emerge as a significant problem in the southern region... Subproject 3 continues existing monitoring and surveillance of new races and pathogen threats; this subproject will link with newly appointed grains biosecurity officer in SA. Subproject 4 focusses on rebuilding a joint capability in the southern region to address key issues in cereal nematology, most critically preventing CCN re-emerging as a significant problem...

Pythium root rot is often misdiagnosed, but new research is increasing our knowledge of damage caused by the disease and offering new control options.. Now research is showing that Pythium can have a big effect on crop growth through the season, resulting in substantial reductions in productivity, even in the absence of 'damping-off'... Results from three years of field trials with wheat demonstrated that an in-furrow application of the Trichoderma inoculant at seeding resulted in: improved crop emergence; reduced levels of Pythium inoculum and root infection; and increases in yield...

In mixed farming systems grazing of the pasture phase can be used to minimise weed burdens but for continuous croppers, or within the cropping phase of mixed farming, some tillage might be needed for integrated weed management... From an overall systems perspective, limited and strategically timed tillage could form part of a productive, sustainable system... A central question emerges : How much damage is done to soil by occasional tillage, strategically applied, in an otherwise no-till system We seek to investigate this question based on the hypothesis: That the agronomic and economic benefits of a strategic tillage operation exceed any agronomic costs due to damage to soil structure...
