Three top tips to stop crown rot: rotate crops, observe plants for browning at the base of tillers and test stubble and soil... Reducing the risk before planting Reducing inoculum levels is vital to managing crown rot... In the short term these practices can increase infection rates in the next Figure 6: Crown rot distribution cereal crop, as broken up in infected cereal stubble...

Rhizoctonia root rot is an important disease of cereals in both the southern and western regions of the Australian grain belt... Experiments in western and south eastern Australia have shown that grass-free canola provides an effective break following cereal crops... Experiments in Western Australia and southern Australia have shown that in-furrow fungicides produced greater and more consistent yield responses than seed treatments alone...

SARDI's Dr Alan McKay says take-all is the disease likely to catch growers out... Inoculum levels are the highest in more than a decade and growers and advisers managing intensive cereal or cereal/pasture rotations should plan ahead to avoid yield loss later in the season... "If the paddock must be sown to a cereal, then consider barley because any yield losses will be only half that of wheat's potential losses, but inoculum levels will continue to increase."..

Crop sequence does affect Rhizoctonia.. Non-cereal break crops, especially canola, can reduce inoculum levels of Rhizoctonia, despite still being susceptible to damage by this root pathogen - By Vadakattu Gupta.. , data from this work and from previous root disease research is being used to build the soil-borne disease component of the Land-Use Sequence Optimiser (LUSO) model (see page 10)...

Rhizoctonia bare patch disease remains an important but unpredictable disease for cereals in the southern Australian agricultural region... Management of natural disease suppressive ability of soils has been suggested as a potential solution to control Rhizoctonia bare patch disease... The project will address (i) the shorter-term solutions such as rotation, tillage and fungicides to reduce disease incidence and increase plant growth and yield and (ii) will develop new knowledge that will assist in a longer-term control of Rhizoctonia through improving our understanding and management of natural soil suppressive activity & improved prediction of disease occurrence...

Research sheds light on Rhizoctonia control.. Research sheds light on Rhizoctonia control The use of break crops significantly reduces Rhizoctonia inoculum levels, but this beneficial effect lasts only until the end of the following cereal crop... The lower levels are maintained through to the end of the next summer reducing the risk of Rhizoctonia damage to the crop grown in the year following the break crop. "..

New fungicides, Vibrance and EverGol Prime have been registered as seed treatments to suppress Rhizoctonia.. Vibrance and EverGol Prime have been evaluated as seed treatments to suppress Rhizoctonia in field trials conducted by SARDI and DAFWA in 2011 and 2012... The type of soil opener used affects levels of Rhizoctonia during seedling establishment...

Precision sowing of cereal crops between previous winter cereal rows (inter-row sowing) has the potential to limit the severity and incidence of CR and common root rot (CRR) in a no-till farming system (Ground Cover Issue 57)... Demonstrated that canola and mustard are excellent breaks for CR in northern New South Wales (NSW)... During the five years of this project , 2986 plots, 4208 individual rows and 986 on-farm samples were established, maintained and assessed for various disease management options...
