Methods of Weed Control Weed Control Methods Overview (using a combination of lecture and visual aids): Cultural Control: Explanation: This involves changing farming practices to reduce the environment in which weeds thrive. Examples include crop rotation, selecting weed-resistant crops, and proper spacing. Visual Aid: Show images of crop rotations or cover crops. Mechanical Control: Explanation: This involves physically removing or cutting weeds. Examples include mowing, tilling, or hand-pulling. Visual Aid: Show images of tillers or hand tools used for weeding. Chemical Control (Herbicides): Explanation: The use of chemical herbicides to kill or inhibit weed growth. Discuss both selective and (B) MECHANICAL WEED CONTROL Tilling: Explanation: Tilling involves turning the soil to uproot weeds and incorporate them into the soil. Visual Aid: Show images of tilling equipment (e.g., rototillers, plows). Advantages: Effective for controlling deeprooted weeds. Disadvantages: Can damage beneficial soil organisms, lead to soil erosion, and may promote weed seed germination if Hands-On Weeding: non-selective herbicides. Pros and Cons: Quick results, but concerns about chemical runoff and harm to the environment. Visual Aid: Show images of herbicide application. Biological Control: Explanation: Using natural predators or pathogens (like insects, goats, or fungi) to control weed populations. Pros and Cons: Sustainable but may take time and effort to manage. Visual Aid: Show examples of biological control agents. Integrated Weed Management: Explanation: Combining multiple control methods for more effective and sustainable weed management. Example: Using cultural practices in combination with herbicides or biological control methods. Visual Aid: Diagram showing integration of multiple methods. Mulching and Ground Covers: Explanation: Using organic or plastic mulches to prevent weeds from getting sunlight or from sprouting. Visual Aid: Show images of mulched garden beds. overdone. Mowing: Explanation: Mowing cuts weeds at ground level, preventing them from flowering and spreading seeds. Visual Aid: Show images of mowers (e.g., push mowers, ride-on mowers). Advantages: Quick and easy for controlling weeds in lawns and grassed areas. Disadvantages: May need to be done repeatedly to keep weeds from regrowing. Hand-Pulling: Explanation: Handpulling involves manually removing weeds from the soil, usually by the roots. Visual Aid: Show images of hand tools like hoes and weed pullers. Advantages: No chemicals involved, very effective in small garden areas. Disadvantages: Timeconsuming and laborintensive for large areas. Hoeing and Weeding: Explanation: Using hoes or other tools to cut or scrape weeds from the soil surface. Visual Aid: Show images of different types of hoes (e.g., stirrup hoes, garden hoes). Advantages: Can cover large areas relatively quickly, doesn't disturb soil structure as much as tilling. Disadvantages: Requires physical effort and skill for effective weed removal. Flame Weeding: Explanation: Flame weeding uses a propane torch to burn weeds, especially in cracks or between rows of crops. Visual Aid: Show images of flame weeders. Advantages: Environmentally friendly, quick, and effective for killing small weeds. Disadvantages: Only effective on young, small weeds and requires careful handling to avoid fires. Pros and Cons of Mechanical Weed Control: Create a table on the board listing the advantages and disadvantages of each method discussed. Lead a class discussion on when each method might be most useful. For example, when would hand-pulling be better than tilling, or when might mowing be better than hoeing? G. Finding practical applications of concepts and skills in daily living Group Activity: Divide the class into small groups and give each group a different scenario (e.g., large farm, home garden, urban landscaping, etc.). Each group discusses and decides on the best methods of weed control for their given scenario. Encourage students to use the methods discussed and weigh the pros and cons for each. Group Presentations: Each group presents their chosen weed control methods to the class. Group Discussion / Scenario-Based Problem Solving: Divide the class into small groups and give each group a different scenario (e.g., a large farm with extensive weeds, a small home garden, a community park). Ask the groups to decide which mechanical weed control methods would work best for their scenario and explain why. Allow for questions and discussion after each presentation. H. Makinggeneralization s and abstractions about the lesson Ask students to reflect on the following question: Summarize the methods of weed control discussed during the lesson. Emphasize the importance of using sustainable practices that balance effectiveness with environmental responsibility. Summarize the mechanical methods of weed control covered in the lesson: tilling, mowing, hand-pulling, hoeing, and flame weeding. I.

A) It involves the use of chemicals to kill weeds. B) It focuses on modifying farming practices to discourage weed growth. C) It uses biological agents like insects to control weeds. D) It focuses solely on the use of physical tools to remove weeds. 2.How can crop rotation help in reducing weed populations? A) It limits the types of weeds that can grow by constantly changing the environment. B) It uses herbicides to kill weeds after every crop season. C) It plants only one crop every year to weaken weed roots. D) It ensures weeds are watered less frequently. 3.

B) Mowing removes the flowers and seeds of weeds, limiting their ability to spread. C) Mowing helps fertilize the soil and promote weed growth. D) Mowing provides shade to prevent weeds from sprouting. 4. Why might handpulling weeds be an effective mechanical control method in small gardens but not on large farms? A) Hand-pulling is cost-effective for large farms and requires minimal labor. B) Hand-pulling is time-consuming and labor-intensive, making it impractical for large areas. C) Hand-pulling weeds is only effective in wet conditions. D) Hand-pulling eliminates the need for any other weed control methods. J. Additional activities for application or remediation V. REMARKS VI. REFLECTION Reflect on your teaching and assess yourself as a teacher. Think about your students’ progress this week. What works? What else needs to be done to help the students learn? Identify what help your instructional supervisors can provide for you so when you meet them, you can ask them relevant questions. Teaching about different types of weeds was fun and practical. Students learned how weeds like dandelions, crabgrass, and aquatic weeds affect gardens and farms. They connected the lesson to real-life examples of weeds they see in their own yards.
