To assess the new products with a range of application strategies and compared them to other management options (tillage, zinc, starter nitrogen, deep sowing, fluid fertiliser and late sowing) which can change the impact of rhizoctonia on crop production.
At Minnipa in 2013 there were cereal yield responses to fungicide treatments in both wheat (up to 14% better than no fungicide) and barley (up to 12 % better than no fungicide but not all strategies were effective). However there were still visual Rhizoctonia patches present. In-furrow fungicide applications were more effective than seed treatments. Tillage, starter nitrogen and zinc produced similar yields to many of the fungicide treatments. A three week delay in seeding reduced yield by nearly one third. Fungicide treatments did not prevent an increase in Rhizoctonia inoculum levels during a cereal phase.
