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...

keY points a break crop is any crop sown to provide diversity to help reduce disease, weed and pest levels in a paddock... the decision to grow a break crop is also complicated by many interactions through the cropping sequences including disease and herbicide carryovers and economic issues such as capital investment for new equipment or storage... pulses and oilseeds can be damaged in a flight auger, and alternative designs including belt shifters are preferred...

Detections of fusarium crown rot in Western Australian cereal crops have increased this season, particularly in central and northern cropping regions... The Department of Agriculture and Food (DAFWA) has reported constant demand this season on its diagnostic service, AGWEST Plant Laboratories (APL), to identify root diseases including crown rot present in samples... The key message to growers from DAFWA researchers including Daniel H berli and Shahajahan Miyan is to test wheat and barley crops before or at harvest if they are showing signs of crown rot or other soilborne diseases and pests such as rhizoctonia bare patch and root lesion nematodes (RLN)...

Horsham workshop to get to the root of cereal diseases.. Identification of cereal root diseases will be the focus of a Grains Research and Development Corporation-funded workshop in Horsham next month... Designed for agronomists, advisers, consultants and growers, the workshop on February 29 will provide information and technical advice for managing and identifying cereal root diseases in the low and medium rainfall zones...

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...

There has been a considerable increase in the incidence of crops affected by root lesion nematode (RLN) throughout the Western Australian (WA) cropping region... The recent root disease survey showed that the highest levels of all root diseases in WA are in the southern high rainfall zone... The objectives of the project are to:1) Identify sites in WA that are suppressive to one or more root diseases of wheat including take-all, rhizoctonia root rot, crown rot and RLN. Sites will be selected from three past and current projects including the DAFWA "Profitable crop sequencing in WA" [P. WHITE, M. HARRIES] project (which will establish 150 focus sites at which inoculum level and disease incidence will be measured), the "Soil Quality" [D. MURPHY] project (which has previously established a large number of geo-referenced monitoring sites around the WA agricultural region and the inoculum level was measured), and the DAFWA 2006-2008 cereal root disease survey sites [DAW00159]...

Western Australian researchers are a step closer to answering this question, having identified several paddocks which potentially suppress diseases including take-all, crown rot and rhizoctonia barepatch, and pests like root lesion nematode (RLN)... Daniel Huberli "Paddocks which had a high to moderate level of DNA for a disease pathogen, but a low expression of the disease, were deemed potentially disease suppressive," Dr H berli said... Dr H berli said the next step of the research aimed to identify the beneficial micro-organisms present in disease suppressive paddocks...
