Economic considerations, i.e. damage created outweighs cost of controls, should be considered at all times.

• A. True
• B. False
• C. Only for expensive pests
• D. Never influence decisions

Answer: (A)

In pest management, decisions are made by weighing the expected crop losses against the cost of control. If the anticipated damage from pests would exceed what you’d spend to control them, applying treatment makes economic sense; if not, holding off saves money and reduces unnecessary inputs. This is built on the idea of economic injury level—the pest density at which the value of expected yield loss equals the cost of control—and the economic threshold, which signals when action should begin to prevent reaching that level. So economic considerations should be part of every management decision, guiding when to spray or not. If you ignored economics, you might spray when it isn’t cost-effective or miss an opportunity to protect yield when it would be, leading to wasted money or greater losses. Therefore, always factor the potential damage and the cost of controls into your decision.
