Groundsel, Senecio vulgaris L., is one of four weed species selected for detailed studies in the framework of the new COST action "Biological Control of Weeds in Crops". Groundsel was selected because of its economic importance and its suitability for biological control, and to serve as model species to study underlying principles of biological control. Groundsel is mainly a problem weed in horticultural crops, due to its favorable biological attributes like short generation time, large-scale seed production, long-range seed dispersal and rapid germination throughout the year, but also because of its rapid formation of s-triazine resistant populations and partial unsensitivity to phenylurea herbicides. The biological control strategy is based on the use of the half-cyclic, autoecious rust fungus, Puccinia lagenophorae Cooke, which naturally occurs throughout Central Europe. Artificial inoculation in early spring and combinations with necrotrophic fungi and low dosage applications of herbicides will be studied, amongst others, to increase the efficiency of the rust. The procedure of the project, which has recently been started, is briefly outlined and discussed
