What can be a direct effect of pesticide overuse?

Increased pest resistance
Improved crop yields
Decreased environmental contamination
Enhanced effectiveness of all pesticides

The correct answer is: Increased pest resistance

The direct effect of pesticide overuse is increased pest resistance. When pesticides are applied excessively or improperly, pests may be exposed to sub-lethal doses of the chemical, allowing them to survive and reproduce. Over time, these surviving pests may develop genetic resistance to the pesticides, leading to populations that are harder to control with the same chemicals. This resistance can escalate over time, making pest management more challenging and often requiring stronger or more toxic chemicals to achieve the same level of control. In contrast, improved crop yields would typically derive from appropriate and strategic pesticide application, not overuse. Decreased environmental contamination is generally a goal of responsible pesticide use, not a result of overuse. Enhanced effectiveness of all pesticides contradicts the principle of developing resistance, as overused pesticides lose their effectiveness against resistant pest populations. Therefore, the correct understanding of pesticide management involves ensuring balanced and judicious usage to avoid the consequence of increased resistance.
