Re: CULT: Fungal and Bacterial Leaf Spot

Oops - sorry folks.

Bacterial leaf spot is caused by various species of Xanthomonas,
Pseudomonas, and Erwinia across a huge range of plant species..  I just
assumed it was the same bacterial rot organism that was hitting the
rhizomes.

Thanks for the correction Anner.

As for prevalence of fungal spot vs bacterial spot, keep in mind that
Bill didn't know what a June bug is.  A big noisy green winged insect
common across the entire southeast and known by every kid who every
picked blackberries in the region, character in the saying 'fast as a
duck on a June bug'.  So he may not know prevalence of spot disease
vectors everywhere. :-)
