To look at the impact of break crops on Rhizoctonia inoculum in 2013 and of crop management on disease expression in the following cereal crop.
2012 was a set up year for the Rhizoctonia best bets demonstrations. Fungicides banded with fluid fertilisers at seeding did not reduce Rhizoctonia in the following cereal crop.
