Which statement describes the movement of neonics within plant tissue?

• A. They move upward in xylem sap and can reach nectar and pollen.
• B. They are confined to the root zone and do not reach aboveground tissues.
• C. They are not systemic and do not translocate within the plant.
• D. They degrade immediately upon entering the plant.

Answer: (A)

Neonics are systemic insecticides, meaning they move through the plant after uptake. When the chemical is taken up by roots, it travels with the water stream in the xylem from roots toward the shoots as the plant transpires. This upward movement carries the compound into aboveground tissues, including where nectar and pollen are produced. Because of this xylem-based translocation, residues can be found in nectar and pollen, which is why pollinator exposure is a concern. They aren’t confined to the root zone, they are not non-systemic, and they don’t degrade instantly upon entering the plant; they persist long enough to be transported to various tissues.
