Ticks in Iowa

With the arrival of spring, ticks are starting to be sent to our office for identification. So far, most of these ticks have been either the adult stage or nymph stage of the lone star tick or the American dog tick. The following is a review of a previous article.

Oak Anthracnose

Anthracnose is a fancy term for certain leaf spot or leaf blight diseases. Cool and wet spring conditions favor the fungi that cause anthracnose. Oak anthracnose has been common this spring. Browning of the leaf tissue occurs, especially along the margins of the leaves and also along the veins of the leaves. When severe, much of affected leaves can appear papery brown and leaves may fall from the tree.
