Pest and disease damage to white clover (Trifolium repens) in Europe
1995

Despite its well recognised attributes for agriculture, white clover does not always thrive. It has become apparent that a major contributory reason for this is the ravages of various pests and diseases. Sitona weevils, slugs (e.g. Deroceras), various nematodes, especially stem nematode (Ditylenchus dipsaci) and cyst nematodes (Heterodera trifolii), and the fungal disease, clover rot (Sclerotinia trifoliorum), are all implicated. The significance of other foliar fungal diseases has not been fully evaluated although leaf spots are common as are several viruses and although all these can reduce yield, vigour and competitiveness, effects are largely unquantified. Losses of clover seedlings caused by slugs, Sitona and other organism are also significant
