What is the main purpose of a systemic pesticide?

The main purpose of a systemic pesticide is to be absorbed and move within the plant. When applied, systemic pesticides are taken up by the roots, leaves, or stems, and then transported throughout the plant's tissues. This internal movement allows the pesticide to protect not only the parts of the plant that are directly treated but also those that may be affected later, including new growth.

This characteristic of systemic pesticides enhances their effectiveness against certain pests, as the active ingredients can be present throughout the plant, making it difficult for pests to avoid exposure. In contrast to other types of pesticides that rely solely on contact with pests or repellent properties, systemic pesticides provide a more comprehensive and longer-lasting form of protection against infestations.
