Pear trellis rust is caused by the fungus Gymnosporangium sabinae. It was introduced into the United States from Europe in the 1990s and has been progressively spreading through states in both the East and West. The disease affects common pear, callery pear, and several species of juniper/eastern red cedar.
Adult sawflies are often similar in appearance to flies or wasps.

The bacteria themselves live in the xylem tissue and gather in clusters called biofilms. These ‘bunches’ of bacteria clog the xylem and block water transport,… Read More Treating Bacterial Leaf Scorch
