Ornamental and Turf Pesticide Applicators Practice Exam

Which of the following cultural practices helps with weed management?

1. Planting invasive species

2. Planting a turf species that is adapted to the site

3. Fertilizing constantly

4. Removing all grass

The correct answer is: Planting a turf species that is adapted to the site

Planting a turf species that is adapted to the site is beneficial for weed management because it creates a healthy and competitive environment that can suppress weed growth. When the right turf species is selected for the specific conditions of the site—such as soil type, sunlight availability, and moisture levels—the plants are better able to thrive. A vigorous, well-established turf can outcompete weeds for nutrients, water, and light, thereby reducing the chances of weed proliferation. In contrast, planting invasive species can lead to environmental disruption and does not aid in effective weed management. Fertilizing constantly can contribute to nutrient imbalance and may inadvertently promote weed growth if not managed correctly. Removing all grass eliminates the existing plants that could suppress weeds, often leading to an unmaintained area where weeds can easily take over. Thus, selecting an appropriate turf species is a sound practice that supports ecosystem health while effectively managing weed populations.
