New fungal diseases, new control dates in rape?

, : New fungal diseases, new control dates in rape?. DLG Mitteilungen 103(7): 340-343

A table is given of important fungal diseases of rape, with their causal organisms, importance in Schleswig-Holstein, GFR, and control measures. Times of symptom appearance are given by crop developmental stage. It is argued that mild winters may favour the development of diseases such as stem rot (Sclerotinia sclerotiorum) and Phoma leaf spot (Leptosphaeria maculans) which are usually severe only in the S. of the country; appropriate control measures are discussed.
