Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...
Small broomrape (Orobanche minor Sm.) is a parasitic weed that recently has become troublesome in red clover seed production in Oregon. It was identified
in a single red clover seed production field in 1998, and the number of infestations increased to 15 by 2000 and 22 by 2001.
Recent concerns about surface water quality near agricultural production areas have stimulated interest in “best management practices” to reduce the risk of off-site sediment, pesticide, and nutrient movement. Vegetative filter
strips can be one component of an integrated management system to reduce these risks.
