Linda--Not to prolong this endlessly, but how can you be sure that it is
insect control that handles your friend's leaf spot problems?
Traditionally, leaving space between clumps for good air circulation is
touted as the best preventative, along with a thorough clean-up in spring
and fall.    How closely are her plants spaced?

Somewhere it is written that if you can keep fungal leaf spot out for two
years, it will be gone for good unless some comes in on new plants.

Still skeptical about insects spreading fungal leaf spot!

Best wishes, Bill
