What is a systemic insecticide?

A systemic insecticide is characterized by its ability to be absorbed and transported throughout the plant’s tissues. This means that when a systemic insecticide is applied, it can move within the plant, reaching areas that are not directly treated, such as leaves, stems, and roots. Consequently, any insects that feed on the plant will be affected, even if they are not in direct contact with the insecticide itself.

This is particularly advantageous for managing pest populations, as it allows for a more comprehensive approach to pest control. This method also improves effectiveness against insects that are difficult to reach or that may hide in the plant. In contrast, insecticides that remain on the surface may only impact pests that come into direct contact with those surfaces, limiting their efficacy against hidden or burrowing insects. Therefore, the ability of systemic insecticides to move through the plant is what makes them a powerful tool in integrated pest management strategies.
