Plant Diseases

Welcome to the Utah State University plant disease site.

Effective disease control depends primarily on early, accurate identification of the disease and the causal agents. In most cases, it is too late to control a disease on a plant once the disease appears. However, timely control measures can prevent the disease from spreading to other plants.
