UNIT GOAL:  Students will identify the types of pathogens and pests that 
            infect plants, identify symptoms, and describe control.

____________________________________________________________________________

UNIT OBJECTIVES:  Upon completion of this unit, the students will be able 
                  to:

1.  Discuss how pests and disease affect quality grades of produce.

2.  Distinguish between pest prevention, suppression, and eradication.

3.  Define integrated pest management.  (IPM)

4.  Discuss ways to implement IPM principles into a management program.

5.  Explain the differences between cultural, mechanical, biological, and 
    chemical control.

6.  Demonstrate examples of cultural, mechanical, biological and chemical 
    control.

7.  Discuss common diseases in your area.

8.  List possible ways that diseases are spread.

9.  Summarize the relationship of proper plant nutrition with improved plant 
    health.

10. Explain the effect of diseases on development, growth, and production of 
    plants.

11. Describe a nematode of your choice, the type of damage it does and the 
    plants it infests.

12. Differentiate between bacteria, fungi, virus and nematodes.

13. Identify vectors that spread plant disease.

14. Summarize the use of insect pheromone traps as indicators for spray 
    programs.

15. Collect and mount three beneficial insects and discuss how they are 
    helpful.

16. Collect and mount five harmful insects and list the crops they infest.

17. Draw and label the parts of an insect. 

18. Draw and label the parts of a mite, spider or tick. 

19. Draw and label the four stages of growth of an insect species which goes 
    through a complete metamorphosis (holometabolis: e.g., bee, moth, 
    etc.).

20. Discuss why insects that undergo a complete metamorphosis are the most 
    damaging to plants (e.g., different stages can cause different damage).

21. List and discuss five ways weeds cause damage and production loss. 

22. Collect, press, and mount fifteen weeds common to your area. (Use flower 
    and/or seed stage.)

23. Identify the difference between a contact and a systemic pesticide. 

24. Compare the effects of selective and nonselective herbicide. 

25. List the three plant growth periods when herbicides can be applied and 
    advantages of each, namely preplant, preemergent, and post-emergent. 

26. Demonstrate four types of chemical application including band, spot, 
    broadcast, and direct spray. 

27. Use approved safety measures when using chemical pesticides.

28. Describe the four toxicity categories of pesticides and the safety 
    regulations governing them.

29. Understand that many factors go into making a control decision.  If 
    an insecticide is used, selection of the "insecticide" is based on 
    several factors.  Use of insecticides requires consideration for 
    hazards to people wildlife, environment, and natural enemies.
