To reduce the number of applications needed to control fungal disease, which pesticide type is preferred?

• A. Systemic Fungicides
• B. Contact Fungicides
• C. Biological control
• D. Nutrient additives

Answer: (A)

Systemic fungicides are absorbed by the plant and moved to all parts, including new growth. Because they circulate inside the plant, they provide protection beyond the application site and can guard new tissues as the plant grows. That means you can achieve effective disease control with fewer applications, since a single treatment can cover more of the plant over time. In contrast, contact fungicides stay on the surface and must be reapplied more frequently, especially after rainfall or as new leaves emerge. Biological control relies on living organisms and environment for effectiveness, which can require more frequent or carefully timed applications, and nutrient additives aren’t fungicides at all. So, to minimize the number of applications while maintaining control, a systemic fungicide is the best option.
