Which of the following is NOT an example of Mechanical Control?

Mechanical control methods in pest management typically involve physical means to manage pests rather than chemical applications. Traps, heat and cold treatments, and electrocution are all forms of mechanical control because they directly affect pests' health or behavior through physical methods.

Traps are physical devices designed to capture or kill pests. Heat and cold treatments involve using temperature extremes to eliminate pests, such as heat treatments for termites or cold treatments for certain insects. Electrocution methods involve killing pests using electric shock.

Fertilizers, on the other hand, are substances that are added to soil or plants to promote growth and do not directly control or eliminate pests. They address nutritional needs rather than pest management and therefore fall outside the category of mechanical control methods. This distinction is why the correct choice identifies fertilizers as the option that does not exemplify mechanical control.
