Hi Elaine,

At the recent Northeast Potato Technology Forum in PEI, if I
understood it correctly, it was said that Chitin is a component of
shells and stimulates chitinase producing bacteria. Chitinase is the
natural substance that breaks down chitin.

Fungi (it was not said what types of fungi) cell walls also contain
chitin so stimulating bacteria that "feed" on chitin in the shells,
increases the bacteria that will break down fungi (again what kind??)
too.

Late blight is an oomycete and so is pink rot, so it sounds like we
may have a real key here since both are bad potato diseases in our
part of the world - especially late blight. If the fungi they were
refering to at the forum are primarily oomycetes and not the
basidiomycetes, that would really be great.

Do you have any input on this?

Thank you,
Tim Livingstone
