2. Be familiar with types of pathogens, their signs and symptoms, disease triangle,

            Kochs postulates.

3. Study historically important disease epidemics, their primary causes, pathogens, etc.

4. Review the disease cycle-inoculation, penetration, infection, dissemination, survival.

5. Know examples of pathogen-produced enzymes, toxins, and growth regulators,            including the pathogens that produce them.

6. Be familiar with and know examples of means that plants use to defend themselves

            from pathogens, including structural, and chemical, induced, and preformed

means.

7. Understand the difference between compatible and incompatible interactions, the

            hypersensitive reaction, and the gene-for-gene theory, SAR.

8. Know plant resistance terms including horizontal, vertical, tolerance, escape, non-host.

9. Study the different types of control: cultural, biological, and chemical and know which

            types of diseases each would work best for.
