A local trial in 2009 has also shown that nodulation may be reduced where inoculants are applied as a slurry on to fungicide treated seed... In the past, inoculation has usually been done by applying root nodule bacteria in peat slurry to the seed and sowing on the same day... The peat granules had a significant increase in nodulation when seed was treated with fungicide...

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...

The DNA test detects both Fusarium culmorum which can cause crown rot but is generally considered to be uncommon in northern NSW from previous studies and F.graminearum which is the main pathogen causing Fusarium head blight in winter cereals... In collaboration with NSW DPI District Agronomists, 248 focus paddocks were assessed around sowing in 2011 in twelve agronomy districts (19-24 paddocks/district) ranging from Dubbo in the south up to the Qld border in the north and west to Warren, Walgett and Mungindi... Root lesion nematodes (RLN) are widespread in central and northern NSW with either species being detected in 82% of the 248 paddocks assessed in this random survey...

The DNA test detects both Fusarium culmorum which can cause crown rot but is generally considered to be uncommon in northern NSW from previous studies and F.graminearum which is the main pathogen causing Fusarium head blight in winter cereals... In collaboration with I&I NSW District Agronomists, 132 focus paddocks were assessed around sowing in 2010 in twelve agronomy districts (10-12 paddocks/district) ranging from Dubbo in the south up to the Qld border in the north and west to Warren, Walgett and Mungindi... Distribution and potential importance of Pratylenchus neglectus in central and northern NSW Pratylenchus neglectus ( Pn ) was widespread being detected in 10 of the 12 agronomy districts but generally had a lower distribution within districts than Pt of between 10 to 75% of random paddocks...

No matter whether chickpea seed is acquired commercially or grower retained on-farm, it is important that it is of high quality... Poor quality seed can result in low plant establishment due to poor germination, vigour and/or disease... Seed size can also be quickly calculated at home by counting out 200 seeds and weighing - multiply the weight (grams) by five to get a 1000-seed weight; or divide 200,000 by the weight (grams) to get number of seeds per kilogram (depending on your preferred method of calculating seeding rates)...

It is extremely important to use farm management practices that maintain organic matter levels, especially biologically available organic matter in our soils... Australian soils are inherently low in biologically available carbon carbon inputs have a major influence on soil biological activity... For an introduced biocontrol agent to be effective it must first survive, establish, acclimatize and grow in field soils and interact with the pathogenic organisms alone or in the presence of plant...

Crop residues are one of the major sources of carbon for soil biota in low fertility agricultural soils of Southern Australia and stubble retention can provide benefits through changes in soil physical, chemical and biological properties... It is generally believed that stubble retention can provide benefits from improvements to different biological properties (Table 2)... Conservation farming practices offer potential to increase the supply of nitrogen to crops by modifying the composition of different soil pools of C and N and the nature of microbial activities that mediate the N cycling processes...

The aim of the project is to apply the new genetic model for wheat, Brachypodium distachyon, to speed up gene discovery in wheat root systems... The objectives are to (1) assemble a collection of diverse Brachypodium germplasm for this project and other Australian researchers; (2) screen Brachypodium genotypes for variation in root vigour, architecture, water uptake and tolerance to wheat root pathogens, and (3) identify genomic regions and markers associated with root traits in wheat using Brachypodium... http://www.nature.com/news/2010/100728/full/466552a.html - international; 53,000 circulation; ~400,000 readership - Impact factor 32 Peer reviewed journals Brkljacic et al (19 international authors including Watt) (2011) Brachypodium as a model for the grasses: Today and the future...
