Birch
White birches are not well adapted to Missouri. Consequently, they seldom
survive more than a few years. River birch is very reliable and relatively problem
free.
Anthracnose

Small, irregular to circular brown spots with dark margins.

first application at bud break and the second 10 to 14 days later. Under wet conditions,
apply a third spray 10 to 14 days later.
