Abstract:The area of maize has increased in several European countries in recent years. In Denmark, the area has increased from 10,000 ha in 1980 to 185,000 ha in 2011. Initially only silage maize was cultivated in Denmark, but in more recent years the area of grain maize has also increased. Farms growing maize have often grown maize consecutively for several years. This leads to significant amounts of debris building up in the fields, which serves as an important source of inoculum for diseases when new crops are grown. In recent years, leaf diseases have caused production problems over several seasons. Two major diseases have been identified: Eyespot (Kabatiella zeae) and Northern leaf blotch (Exserohilum turcicum). Other diseases, including Southern maize leaf blight or maydis leaf blight, caused by Bipolaris maydis, and Northern corn leaf spot, caused by Bipolaris zeicola, may potentially play a role but have not yet been clearly verified as major diseases in Scandinavia.
