A pesticide described as systemic is characterized by which property?

• A. Kills only on contact
• B. Is absorbed and translocated throughout the plant
• C. Remains on the surface after application
• D. Is not absorbed by the plant

Answer: (B)

Systemic pesticides work by being absorbed by the plant and then moved to all parts of it. Once taken in, they travel through the plant’s vascular system, reaching new growth and tissues so pests that feed inside the plant or on new leaves are exposed to the chemical. This internal distribution is what protects areas you didn’t directly spray and helps control pests that aren’t touched by surface residues. If a product stays on the surface, isn’t absorbed, or isn’t moved within the plant, it won’t be systemic.
