What is the effect of systemics in pest control?

Systemic pesticides are designed to be absorbed by plants or animals, allowing them to move throughout the organism's tissues. This absorption means that when pests feed on the treated plant or organism, they are exposed to the pesticide, which can lead to effective control of the pest population. This characteristic makes systemics particularly useful for controlling pests that are difficult to reach or target since they can act from within the organism rather than just on contact.

By being inside the plant or organism, systemic pesticides can provide a longer-lasting effect against pests compared to contact pesticides, which only work on the surfaces where they are applied. This internal action allows for more comprehensive pest management strategies, especially for systemic pests that may hide or consume inner tissue parts.
