title: Transmission of Xanthomonas campestris pv. campestris by the fly Calliphora vomitoria to blooming cauliflower plants (Brassica oleracea) creator: van der Wolf, J. M. creator: van der Zouwen, P.S. creator: Garbeva, P. creator: Köhl, J. subject: Breeding, genetics and propagation description: Xanthomonas campestris pv. campestris (Xcc) is a seed borne pathogen that causes black rot, a destructive disease of cabbage. Exclusion of infec-tions is the most effective way to control black rot in organic seed production. Within this frame, the role of insects in transmission of Xcc to seed was deter-mined. It was found that Xcc survived for three days on flies (Calliphora vomitoria), used for pollination of cabbage plants in tunnels and greenhouses. In tunnel experiments, both the use of Xcc-contaminated flies and brush inoculation of flowers with Xcc resulted in internal seed infections. The implications for seed production are discussed. date: 2006 type: Conference paper, poster, etc. type: NonPeerReviewed format: rtf identifier: http://orgprints.org/7632/1/Xanthomonas-Odense-vanderWolf_et_al.rtf identifier: van der Wolf, J.
