Which term describes certain systemic and locally penetrating fungicides that stop infections that may have occurred hours or days before applications?

• A. Curative
• B. Defoliate
• C. De-thatching
• D. Diameter

Answer: (A)

Curative describes fungicides that are systemic and locally penetrating, able to move within the plant to reach infection sites that already started hours or days earlier and stop their progression. This means they can intervene after the pathogen has begun growing, not just before infection occurs. The other terms don’t fit this idea: defoliate is about causing leaf drop, not disease control; de-thatching is a turf management practice to remove thatch; diameter is simply a measurement.
