If you have tulip fire, the first thing to suspect is cultural conditions.
Tulips demand full sun, good ventilation, and, please, no top dressing with
organic material! Even a mulch of leaves can cause trouble.
Good hygiene is important too: careful removal of faded and diseased flowers
and foliage. Don't compost it! Put it in the household garbage or burn it.
At a guess, the bed your tulips are in may be so contaminated with spores of B.
tulipae now that the best bet would be to move them to a clean, uncontaminated
location.
