I'm interested in improving my lawn care. Navigate to the 'Lawn & Garden' section within the Learning Center. Find information on 'Pre-Emergent' applications. What is the primary purpose of a pre-emergent, and what is one key tip mentioned for its application?
Navigate to the 'Learning Center' page (https://diypestcontrol.com/learning-center.htm). Click on the 'Pre-Emergent' link under the 'Lawn & Garden Information & How-to Guides' section. Identify the primary purpose of a pre-emergent application. Locate and extract one key tip for applying pre-emergent. Synthesize the findings to answer the questions.
The agent successfully navigates to the 'Pre-Emergent' guide page. The agent states the primary purpose of a pre-emergent (e.g., 'to prevent weeds from germinating' or similar phrasing). The agent states one key tip for its application (e.g., 'apply before weeds germinate', 'water in after application', 'do not apply to newly seeded lawns', or similar practical advice).
