Our aim was to investigate the interaction of nitrogen and fungicide in the control of yellow spot in wheat varieties of varying yellow spot resistance... The results of the trial suggest that nitrogen and fungicide are each effective on their own, and also in combination, for managing leaf spot diseases on susceptible wheat varieties... Nitrogen application increases the vigour of wheat plants and number of tillers and can increase yield and may allow for fungicide application to be more effective, particularly on susceptible wheat varieties...

Controlling leaf spot diseases - yellow spot and stagonospora (septoria) nodorum - in wheat-onwheat cropping 1... Early spraying can reduce le;af spot diseases when susceptible varieties are sow; n on wheat stubble.. Where early disease is severe and developing rapidly on susceptible variety & seasonal conditions favour disease development Application at tillering or stem extension delays disease development and increases yield Z31 application most reliable timing for profitability May need additional application at flag leaf emergence..
