What field studies the development of plant diseases and their control?

• A. Plant pathology
• B. Entomology
• C. Soil science
• D. Plant physiology

Answer: (A)

The main idea being tested is which field focuses on how plant diseases develop and how to manage them. Plant pathology is dedicated to understanding disease causes, how pathogens infect and spread in plants, how to diagnose problems, and the various ways to control diseases—from resistant varieties and cultural practices to biological and chemical methods. The other fields there focus on different areas: entomology studies insects, soil science looks at soil properties and their effects on growth, and plant physiology explores how plants function and respond internally. Because the question centers on diseases and their control, plant pathology is the best fit.
