What are two hazards associated with the faulty application of pesticides?

The option indicating increased toxicity and damage to non-target organisms is correct because when pesticides are misapplied, they can lead to unintended consequences that extend beyond the intended target species or area. Increased toxicity can occur when the concentration of the pesticide is too high or is applied inappropriately, leading to harmful levels for not only the target pest but also beneficial organisms and those in the surrounding environment.

Additionally, damage to non-target organisms is a significant concern. Non-target organisms might include beneficial insects, aquatic life, or even plants that are not intended to be affected by the pesticide application. Both of these hazards underscore the importance of following proper application guidelines and techniques to protect the ecosystem and maintain biodiversity.

The other options, while they may contain elements of truth, do not encapsulate the primary hazards associated with faulty pesticide applications as effectively. For instance, damage to aquatic life and overgrowth of weeds could occur but are not directly attributed to the faults in pesticide application itself. Similarly, unintentional pest control, soil erosion, delayed effectiveness, and overspray reflect consequences or technical aspects that are less directly tied to the immediate hazards of increased toxicity and non-target damage. Understanding these specific hazards is crucial for effective pest management and environmental safety.
