Field research was conducted on carrots with the aim of controlling both powdery mildew and Cercospora leaf blight. Research identified traditional fungicides and alternative products that controlled these diseases. Pyraclostrobin, azoxystrobin and tebuconazole controlled both diseases. Sulphur only controlled powdery mildew. There was a difference in the sensitivity of powdery mildew isolates from two different growing regions to azoxystrobin.
