What is a major advantage of systemic fungicides for turf diseases?

• A. They translocate to protect new tissue
• B. They kill only on contact
• C. They are always cheaper than other options
• D. They work only under bright sunlight

Answer: (A)

Systemic fungicides are absorbed by the plant and move through its vascular system, so they can reach and protect new growth as it appears. This means that as turf grows and produces new leaves or shoots, those tissues against which disease could attack are already protected, even if they weren’t directly sprayed. That ongoing protection of new tissue is the key advantage. In contrast, fungicides that kill on contact stay on the surface and don’t guard new growth, and factors like cost or sunlight exposure aren’t defining benefits.
