Calendar-based garden sprays are always recommended to stay ahead of pest problems.

Calendar-based garden sprays are always recommended to stay ahead of pest problems.

• A. Only in organic systems
• B. Depends on pest
• C. TRUE
• D. FALSE

Answer: (D)

Pest management works best when actions are guided by actual pest pressure and crop needs rather than a fixed calendar. Spraying on a set schedule regardless of what pests are present can lead to unnecessary applications, increased costs, and greater risk of problems like pesticide resistance, harm to beneficial insects, and environmental impact. In practice, you monitor pest populations, assess damage potential, and use action thresholds to decide if and when to spray. Timing matters because some pests are present only at certain life stages or times, and mis-timed sprays can miss the window of effectiveness. Rotating modes of action, following label directions, and integrating cultural and biological controls all help reduce reliance on routine calendar sprays while keeping crops protected. So the statement that calendar-based garden sprays are always recommended isn’t correct.
