How does a selective pesticide differ from a systemic pesticide?

The distinction between selective and systemic pesticides comes down to their modes of action and target specificity. A selective pesticide is designed to target specific pests while minimizing harm to non-target organisms, which is a key characteristic that differentiates it from broad-spectrum pesticides. This targeted approach allows for more environmentally friendly pest control.

On the other hand, a systemic pesticide is absorbed by the plant and then transported throughout its tissues. This means that when pests feed on the plant, they ingest the pesticide as well. This type of pesticide can be significantly more effective against pests that are hard to reach with topical applications.

The chosen answer correctly identifies the nature of systemic pesticides, highlighting their ability to be absorbed and distributed within plants. Understanding this mechanism is crucial for applying pesticides effectively and responsibly within pest management programs. A selective pesticide does not negate this property; rather, it focuses on targeting certain pests while leaving beneficial organisms unharmed, making the awareness of these characteristics important for integrated pest management.
