Resistance levels against septoria within each field averaged 40% and peaked at 70%, according to the study by ADAS, HGCA and Rothamsted Research. Manufacturers concede there is a potential problem, but insist that until the practical impact becomes clearer pricing and product advice should not change. Growers must act as if they have resistance and keep triazole fungicide rates up at the imminent T1 spray timing. With physiological benefits set to become more relevant, BASF has the only strobilurin with a label claim of physiological yield benefit in the absence of disease.
