Monitoring and fungicide usage in northern Germany.

摘要

Cercospora beticola is the most important pathogen of sugarbeet in northern Germany. It can cause considerable yield reductions in heavily affected areas, e.g. irrigated areas. An internet-based computerized monitoring system is described. Opus [epoxiconazole] and the newly approved Harvesan [flusilazol + carbendazim] are the most effective fungicides. However, the way forward is to minimize fungicide use and grow resistant varieties..
