The introduction of fungicides from the SDHI group of chemistry has brought improved efficacy to cereal fungicide programmes, and are applied against a wide spectrum of diseases. They have also brought increases in yield in wheat and barley. Not all of the yield benefits can be explained by disease control and this paper reports measurable improvements in the photosynthetic activity of leaves from wheat and spring barley field trials. Fluxapyroxad containing fungicides improved the longevity and chlorophyll content of leaves and the data presented suggested that responses were larger in barley than in wheat. There was preliminary evidence that SDHI chemistry might improve photosynthetic efficiency, specifically through the efficiency of carboxylation.
