LESSON PLANS WITH OBJECTIVES – CROP MANAGEMENT I AND II. INSECT CONTROL OBJECTIVES: 1. Describe the five organic methods of insect control 2. State the primary method of insect control 3. State the last resort in organic insect control LESSON PLAN: 1. Start the class with a discussion of the common belief that the only way to control insects is with chemical pesticides. Have some containers of chemical insecticides and read the cautions to the class. Use Unit 5 power point slides1-9 to talk about the various methods of organic control. 2. Explain how healthy plants can withstand some insect damage and the importance of soil health for plant health. 3. For each of the 5 organic methods of control, explain the mechanism and give an example. When possible, show the class an example of each type. For example, a piece of row cover, a container of Bt powder, and garlic spray would be visuals the students could identify. 4. Identify the need to scout crops and identify the insects present. Use the power point presentation slides 11-77 to talk about when insects are most vulnerable to control and help students identify common insect pests and beneficial insects. The powerpoint Life Cycle of Insects may be used to illustrate the best times for control. 5. If possible, visit a greenhouse and find and identify insects found in the greenhouse. The demo plot should also be scouted for insects and those found brought in for identification and a discussion on the best control plan, if damage is severe. III. DISEASE CONTROL OBJECTIVES: 1. List the three causes of disease in plants. 2. Identify the control method for bacterial or viral diseases. 3. Describe the three steps in disease control. 4. Name the most common cause of plant disease. LESSON PLAN: 1. Ask students what causes disease in humans. Relate their answers to the three cause of disease in plants – bacteria, viruses, and fungi. 2. Uses Unit 5 power point slides 78-83 to explain and illustrate plant diseases. 3. Explain that the only way to deal with bacteria or viruses in plants is to try to prevent the infection. This is true across the board, not only in organic systems. The most common cause of disease, fungi, has a few organic treatments. The web site http://www.apsnet.org/ has an image of the week that you can download and use in your classes. 4. Relate the three steps of disease control to the methods of controlling insects: Identification, life cycle determination, best method of control. IV. WEED CONTROL OBJECTIVES: 1. Identify the time in the weed life cycle that it is easiest to control. 3. Describe four ways to control weeds within the organic standards. LESSON PLAN: 1. Take students to an outside area and point out some of the weeds. Ask the students what they all have in common. There common feature is that they are growing where we don’t want them to grow – this is what makes them weeds. 2. Use Unit 5 power point presentation slides 84-133 to talk about weed control and to help students identify specific weeds. 3. Visit the demonstration plot and identify and Pull the weeds. V. COMPANION PLANTING OBJECTIVES: 1. Define “companion planting”. 2. State three reasons to use companion plants. 3. Describe two factors to consider when deciding on companion plants. LESSON PLAN: 1. Use an analogy of how some people get along well and others don’t to establish the idea of companion planting. 2. Use Unit 5 power point presentation slides 134-135 to explain companion planting and the benefits and disadvantages of companion planting. 3. Use the Table of companion plants to show students the types of plants that are good companions and those that don’t work well together. 4. Remind students that plants can be grouped in families, and ask students to look for patterns in the recommendations for companions, and description of antagonist. 5. Describe crop rotation as a method of control using Unit 5 power point presentation slide 136-137. 6. Use the Crop Rotation Worksheet, Rotation Guidelines, and Yield and Value Worksheet to have students practice designing a rotation and estimating the value of crops they may grow. 7. Conclusion of the unit on slide 137.
