Systemic pesticides are specifically formulated to be absorbed by plants and then translocated throughout their tissues. This means that once a systemic pesticide is applied, it enters the plant's vascular system and can be distributed to various parts of the plant, including leaves, stems, and roots. This method of action allows the pesticide to effectively control pests that feed on the plant, as it targets the pest directly by being present in the sap or tissue they consume.

The absorption and movement within the plant enhance the effectiveness of the pesticide, as it can protect against insects and diseases that may not be addressed by surface-applied pesticides. This quality also allows for longer-lasting protection, as the pesticide remains in the plant for an extended period, continually deterring or killing pests that interact with it. Understanding this mechanism is crucial for proper pest management strategies in arboriculture, as it influences the choice of pesticide based on the type of pest and the plant being treated.
