What is the fourth basic step of IPM?

• A. Detection
• B. Method Selection
• C. Evaluation
• D. Eradication

Answer: (B)

Understanding the sequence of IPM steps helps see why choosing the control method is the fourth step. After pests are detected and their situation is assessed, the next move is to pick the most appropriate management approach. This Method Selection step is where you weigh options such as cultural practices, biological controls, mechanical methods, and pesticides, balancing effectiveness with safety, environmental impact, resistance management, and crop tolerance. The chosen method is then implemented and its effectiveness monitored to decide if further action is needed.

Detection is an earlier step focused on spotting the pest problem, not the fourth step. Evaluation plays a role in deciding whether action is needed, but the explicit fourth step is selecting the method to use. Eradication can be a goal in some cases, but IPM centers on practical, sustainable suppression, not guaranteed elimination.
