Unlocking crop root disease secrets to thwart yield losses.. Researchers are beginning to unravel the behaviour of a complex and damaging crop root disease known as Rhizoctonia, and finding new ways to manage crops to reduce its impact... The fungus can grow and survive in the soil in the absence of a live plant host, the fungus has a wide host range, there are no resistant cereals, and it is strongly influenced by soil and environmental conditions and the seasonal impacts are difficult to forecast," Dr Gupta said...

Other factors increasing Rhizoctonia disease risk includes greater adoption of intensive cereals and reduced tillage (Figure 1)... Disease severity depends on a number of factors including the amount of Rhizoctonia inoculum at seeding, composition and activity of the soil biology community, available soil N levels over summer and at seeding and constraints to root growth including herbicide damage, low soil temperatures during early seedling growth and compaction layers...

Summer weed control reduces root disease.. Controlling weeds and volunteers during the month before sowing, after an opening rain, is a well-known method of reducing the incidence of the root disease Rhizoctonia in the following crop... "We wanted to see if time of control and type of weeds controlled had an effect on the level of inoculum carried over to the following crop," Dr Vadakattu explains...
