Conclusion

At the end of July, generally in the growing area the first symptoms of rust have been observed, and especially in coastal areas. Subsequently, the rust has developed slowly but has increased in development from mid-September. Powdery mildew has developed in the warm and dry period in August, when Cercospora has also increased in strength. In many fields Cercospora has developed relatively more than in previous years. Ramularia has also appeared in many fields and more than usual, but at a relatively low level.
