Ornamental and Turf Pesticide Applicators Practice Exam

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

1. They kill existing pests

2. They translocate to protect newly formed tissue

3. They act quickly on symptoms

4. They are environmentally friendly

The correct answer is: They translocate to protect newly formed tissue

A major advantage of systemic fungicides in managing turf diseases is their ability to translocate through the plant. This means that once applied, systemic fungicides are absorbed by the plant roots or foliage and move within the plant's vascular system. As a result, they can effectively protect newly formed tissue that is vulnerable to disease. This is particularly important in turf management, as it allows for proactive disease management, ensuring that new growth is safeguarded even after the application. In contrast, options related to immediate action against existing pests or being environmentally friendly do not encompass the full capability of systemic fungicides, as they specifically excel in providing ongoing protection rather than acting as an immediate remedy. Additionally, the speed at which they act on symptoms is variable, as systemic contends with plant uptake and distribution within the tissue rather than providing an instant response. Thus, the ability to translocate and protect new growth is what distinctly characterizes the efficacy of systemic fungicides in turf management.
