To minimize plant problems from pests, which criterion is essential when selecting species?

• A. Pest susceptibility
• B. Rate of growth
• C. Light requirements
• D. Water needs

Answer: (A)

Choosing species with low pest susceptibility is the key to minimizing pest problems. When a plant naturally resists or tolerates common pests, it sustains less damage, stays healthier with fewer interventions, and fits well into an integrated pest management approach. Growth rate, light needs, and water requirements affect how well a plant performs in a given site, but they don’t directly reduce pest damage. A plant can fit a site perfectly or grow rapidly yet still suffer heavy pest attack if it’s highly susceptible, so those factors don’t guarantee fewer pest problems.
