Which of the following describes the effects that occur away from the point of contact with a pesticide?

The term "systemic" refers to effects that occur away from the point of contact with a pesticide, indicating that the substance is absorbed into the organism's system and distributed throughout the body. This can happen with both plants and animals; for instance, when a pesticide is absorbed through the roots of a plant, it can affect the entire plant rather than just the area where it was applied.

Systemic pesticides are designed to move through the organism’s circulatory or vascular systems, impacting areas far from where the pesticide was initially applied. This characteristic is particularly useful in targeting pests that may reside in different parts of the plant or organism, as well as in providing prolonged control through long-lasting activity.

In contrast, "local" effects would be confined to the area where the pesticide made contact, while "acute" and "chronic" refer to the timing and duration of effects following exposure. Acute effects typically occur shortly after exposure, and chronic effects develop over an extended period of time with repeated exposure. Thus, understanding the distinction of systemic effects is crucial for effective pest management and safety protocols.
