As the 2008 season unfolds, exporters and growers will be keeping a close eye on Fusarium infection in tulip stocks. Everyone is aware that Fusarium infected tulip bulbs produce ethylene (or, more accurately, the strains of the Fusarium fungus that infects tulips produce ethylene the tulip bulb tissue itself does not), and that one of the major challenges confronting the entire industry is to develop ways to control this problem. As with most complex agricultural problems, the ultimate solution will probably involve many levels, including changes in farming practice, changes in chemical use, changes in cultivar selection (or new breeding efforts), changes in lifting and processing procedures, changes in storage and shipping procedures, and, in North America, changes in storage and handling procedures
