Which type of herbicide is absorbed and translocated throughout the plant?

• A. Contact.
• B. Selective.
• C. Systemic.
• D. Aerial.

Answer: (C)

Systemic herbicides are absorbed and translocated throughout the plant, moving through the vascular system to reach growing points and storage tissues. Because the chemical travels inside the plant, it can kill parts that weren’t directly sprayed, making it effective against perennial weeds and plants with deep or spreading root systems. This internal movement distinguishes systemic products from those that only affect tissue they contact. Selective versus non-selective describes which plants are affected, not how the chemical moves inside the plant, and aerial refers to how the product is applied rather than its movement once inside.
