To examine the integration of the principles of disease management and canopy management in cereal crops.
Taking account of fungicide costs (both application and product) revealed that untreated Teesdale generated the equal highest margins (Table 6-16). With both Mitre and Kellalac the most cost effective treatments were two applications of fungicide based on a GS32 Bayleton followed by Opus, however as stand alone treatments the flag leaf spray of Opus was substantially more cost effective than either Jockey or Impact. The application of Bayleton at GS32 followed by GS39 Opus was slightly more cost effective than the Impact followed by Opus. Impact had an edge over Jockey in this trial in terms of green leaf retention, yield and margin.
