1. Pesticides and Pest Control By Brian Kaestner with thanks to Miller and Clements

2. What is a pesticide?  Broad-spectrum agents  Narrow-spectrum agents  Target species  Nontarget species What are the different types of pesticides?

3. In your groups come up with 3 characteristics of a ideal pesticide.

4. Characteristics of an Ideal Pesticide?  Kill only target pests  Harm no other species  Break down quickly  Not cause genetic resistance  Be more cost-effective than doing nothing

5. Add to your list… Present a case for using pesticides

6. The Case for Pesticides  Save human lives  Increase supplies and lower cost of food  Work better and faster than alternatives  Health risks may be insignificant compared to benefits  Newer pesticides are becoming safer  New pesticides are used at lower rates

7. Now come up with a list against pesticides

8. The Case Against Pesticides  Genetic resistance  Can kill nontarget/natural control species  Can cause an increase in other pest species  pesticide treadmill  Pesticides do not stay  Bioaccumulation/biomagnification  Potential human health threats

9. Pesticide Regulation in the United States ?  Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 1947  Food Quality Protection Act (FQPA) 1996  Food Quality Protection Act (FQPA) 1996

10. What is IPM ?  Ecological system approach  Reduce pest populations to economic threshold  Field monitoring of pest populations  Use of biological agents  Chemical pesticides are last resort

11. Effects of IPM Time Pest density Original pest population Introduction biological control Equilibrium position Equilibrium position Reduced pest population Economic threshold
