									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.
