no need to worry Fred! you can try to apply any of the following: Strike 50 WDG, Terrazole, Heritage. They are also effective as drench. If I were you I'd drench the plat cause these are moveing acropetally in the plant. Use the concentration for spraying on foliage. Re-apply after 2 weeks. you can dust the bulbs in mancozeb before planting or before storage Janos HJungary
