root rot

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...

Research has now identified that crop rotation can have a big influence on the pathogen and disease expression... In trials carried out in four states over four years using a Pythium-selective seed dressing at greater concentrations than commercial products, yield increases of two to 12 per cent were recorded in cereals, five to 25 per cent in canola and five to 35 per cent in pulses... The yield improvements were achieved with only partial disease control...

At the First International Crown Rot Workshop for Wheat Improvement held in Narrabri, NSW, the world's leading researchers on the disease met to discuss the progress of their research... The following is a summary of the global research position, as reported at the First International Crown Rot Workshop for Wheat Improvement held in October in Narrabri, NSW, in 2012... Research to date has focused on seed treatments with results showing some control of crown rot on wheat, with the whitehead rate declining significantly...

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...

Researchers at the 12th International Conference on Precision Agriculture demonstrated many applications of spatial management with potential relevance to Australia.. Researchers from Wageningen, the Netherlands, are using soil texture maps created from gamma-radiometric, electrometric and near-infrared data to vary rates of different herbicides in sugarbeets... It was calculated that only between 17 and 25 per_cent of the 105-hectare paddock required fungicide treatment, depending on seasonal conditions...
