Fosamine (Krenite) is used as a foliage treatment on woody plants and may not show effects immediately; it can also be used as a trimming effect if applied to certain areas. Which statement best describes it?

• A. Foliage treatment for woody plants; effects may appear in following season; trimming possible
• B. Soil-applied pre-emergent herbicide
• C. Non-selective foliar spray
• D. Insecticide for foliar pests

Answer: (A)

Fosamine (Krenite) is a foliage-applied, systemic herbicide used on woody plants. It’s taken up through the leaves and transported within the plant, and its growth-suppressing effects can take time to show up—often appearing in the following season rather than right away. It can also produce a trimming effect when applied to certain areas, meaning growth in those spots is slowed or slowed-looking without an immediate, dramatic kill. This combination—foliar application to woody plants, delayed visible effects, and potential growth suppression in treated areas—best matches how Fosamine is used. It isn’t a soil-applied pre-emergent, it isn’t a non-selective foliar spray, and it isn’t an insecticide.
