botrytis on Fritillaria

Botrytis is not a big problem for me because it's rarely warm and wet at 
the same time in this part of the world. However, it does occur. In 
fritillarias, I have seen it fairly often on F. davisii, and once I bought 
some Chinese frits from Paul Christian that came infected with a stubborn 
form of Botrytis. I had to isolate them and spray them a lot, and some 
still died. Other than that, it seems not to bother them. However, I don't 
allow purchased tulip bulbs into my bulb frames because I believe they are 
often carriers of multiple viruses, bacterial diseases, and other problems. 
Most frits have a different leaf texture than tulips, so it does look a bit 
different -- darkened, moist spots that turn brown. It's important not to 
get the foliage wet during warm weather. This may be a real problem for Jim 
in the mid-Atlantic region.
