Ornamental and Turf Pesticide Applicators Practice Exam

Which of the following weeds is known to spread from rhizomes?

1. Creeping Charlie

2. Bermudagrass

3. Johnson grass

4. Quack grass

The correct answer is: Bermudagrass

Bermudagrass is known for its ability to spread through rhizomes, which are underground stems that grow horizontally and allow the plant to propagate and cover new areas. This characteristic makes Bermudagrass a vigorous and resilient species, particularly in warm climates where it thrives. Creeping Charlie, while often considered a troublesome weed, primarily spreads through stolons and not rhizomes. Johnson grass also spreads mainly through seeds and has a tendency to grow from plant fragments, though it has a different growth habit. Quack grass, similar to Bermudagrass, does spread through rhizomes, but the correct choice in the context provided highlights Bermudagrass specifically for being well-known for its rhizomatic spread. Understanding these differences is crucial for effective weed management and control strategies in ornamental and turf settings.
