Farmer best bet demonstrations for Rhizoctonia management locations
Aims

To look at the impact of 2012 break crops on Rhizoctonia inoculum in 2013 and of crop management on disease expression in the 2013 cereal crop. 

Key messages

In 2013 the Rhizoctonia best bets demonstrations using rotations were over sown with cereal and showed break crops which are grass free are the best option to lower Rhizoctonia inoculum levels.
