What are systemic pesticides?

Systemic pesticides are defined as those that are absorbed by the plant after application and are then distributed throughout its tissues, including leaves, stems, and roots. This characteristic allows systemic pesticides to be particularly effective against pests that feed on various parts of the plant, as the pesticide works internally rather than solely on the surface. By being absorbed, these pesticides can provide longer-lasting protection since they remain active within the plant's system.

This method of action is advantageous especially in managing pests that may not come into contact with the surface application of traditional pesticides. Other methods and types of pesticides, such as those that remain on the surface of plants or are intended to evaporate quickly, do not have the same capabilities as systemic pesticides in terms of internal transportation and prolonged effectiveness. Systemic pesticides can target specific pests more effectively, as their effects are carried throughout the entire plant, offering a full spectrum of control against sap-sucking insects and certain diseases.
