Root Rot of White Clover G. M. Dunn, R. A. Kilpatrick, and H. S. Chow ENDING white clover (Trifolium repens L.), one of the major pasture legumes in the United States, persists poorly. Various factors, including diseases, insects, nematodes, poor management, unfavorable climatic conditions, and plant type, are known to affect persistence. However, their interaction in the field is complex, and the major factors limiting persistence have not been positively identified. Many pathogens have been reported on white clover (6). Root and crown rots are often considered the most important diseases of this species and several fungi have been associated with rapid deterioration of the primary taproot (9, 17). The clover root curculios, Sitona spp., have long been known to attack white clover (8, 16). Their occurrence in
