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.
