Abstract

SUMMARY Green leaf area and net photosynthesis of the flag leaves of Avalon and Maris Huntsman winter wheat crops were studied in relation to grain growth following the application of the fungicide propiconazole at flag leaf emergence. Disease levels were low during grain‐fill, and were not significantly affected by the fungicide. Propiconazole significantly maintained green leaf area and photosynthesis per unit area during the period of rapid flag leaf senescence, but it had no effect on stem weight, grain growth or yield.
