Abstract Broomrapes (Orobanche spp.) are phanerogamic holoparasites that subsist upon the roots of many important crops thus causing considerable yield losses, especially in the drier and warmer areas of Europe, Africa and Asia. The major principles of reducing the seed bank and controlling the weed in the germination and parasitic/ reproductive phases are critically reviewed. Practices to control broomrape include physical methods (weeding, soil tillage, flooding, irrigation, solarization, flaming), chemical methods (soil fumigation, herbicide application, use of germination stimulants) and biological methods (use of resistant or tolerant varieties, cropping systems with trap and catch crops, intercropping, biological control with insects or fungi). Cultural practices which help to avoid germination, infection or strong reproduction of the weed or improve the crop's tolerance should be optimized. However, no single cheap method can control the weed, so integrated management practices are required. Integrated control strategies are site‐ and cropping‐system specific but have in common that measures are taken to kill part of the seed bank, induce the conditioned seeds to germinate in the absence of the commercial crop, kill emerging Orobanche shoots before seed set during growth of the commercial crop and further reduce or avoid damage to the commercial crop.
