Ornamental and Turf Pesticide Applicators Practice Exam

What should you do if you find webbing at the base of grass crowns?

1. Ignore it as it is harmless

2. Apply herbicide immediately

3. Investigate for the presence of Sod Webworms

4. Water the grass more frequently

The correct answer is: Investigate for the presence of Sod Webworms

Finding webbing at the base of grass crowns is an important indicator that warrants investigation, particularly for pests like Sod Webworms. These small caterpillars create silk webs as they feed on grass, which can lead to significant damage if left untreated. By investigating for the presence of Sod Webworms, you can assess the extent of the infestation and determine the appropriate course of action. Understanding the behavior and life cycle of these pests is crucial. Early detection allows for more effective management strategies, potentially reducing the need for extensive pesticide applications and minimizing damage to the turf. In contrast, ignoring the webbing could allow the problem to escalate, resulting in increased damage. Applying herbicide immediately may not address the specific issue, as herbicides are generally targeted at weeds rather than the specific pests. Watering the grass more frequently will not resolve the presence of the webbing or the underlying pest problem. Therefore, investigating for the presence of Sod Webworms is the most suitable and proactive approach.
