Evaluation of rates of flutriafol for control of blackleg of rapeseed

The effect of flutriafol, applied at sowing as fungicide coated superphosphate, on the severity of blackleg disease of rapeseed was studied in the field. Fungicide rates from 50 to 200 g a.i./ha reduced disease severity and markedly increased yields. With blackleg resistant cultivars, economic yield responses were achieved even when disease severity was low.
