Noninfectious diseases of oaks

Abstract

Noninfectious diseases arise primarily from the harmful effects of wound agents, chemical, and adverse environmental factors. Wounds directly result in damage to trees, but they are important primarily as infection courts for pathogenic organisms. Adverse environmental factors affect trees both directly and indirectly. Trees weakened by environmental stresses become susceptible to insects and fungi that normally are unable to attack. These "declines" of oak have occurred frequently in the Northeast and Southeast and will probably increase as concern for environmental quality restricts the use of pesticides.
