Illinois Field Crop Applicators Practice Test

True or false: Monocyclic diseases infect a plant and complete only one generation but don't reinfect during the same growing season. Most root diseases are this way.

Understanding this is critical for effective disease management in field crops, as it affects how farmers and agronomists plan their pest and disease control strategies. It is also important to note that
