What are the two types of harmful pesticide effects?

The identification of the two types of harmful pesticide effects as local effects and systemic effects is accurate because it clearly differentiates how pesticides can harm organisms based on the site of exposure. Local effects refer to damage that occurs at the site of contact, such as skin irritation or respiratory issues when pesticides come into direct contact with an organism. This can lead to immediate and observable symptoms in the area where the pesticide was applied.

In contrast, systemic effects occur when pesticides are absorbed into the organism's system and may affect multiple organs or systems in the body. This can happen when a pesticide is ingested or absorbed through the skin and then distributed throughout the body, leading to more widespread health problems that may develop over time.

By understanding these two categories, applicators can better assess risks associated with pesticide use and implement strategies to minimize both local and systemic harm to humans, non-target organisms, and the environment. This knowledge is essential for safe herbicide application and adherence to regulatory guidelines.
