Activity #2

Work in a group. Do your best to make sure that everyone participates. It’s not a race, take your time and have a good discussion. We will go over the answers together.

View each scenario below. Then, discuss as a group:

  • What plant is this?
  • Is there a real problem?
  • What is the population of the affected plant?
  • Describe the pattern of damage
  • Is the problem spreading, improving or constant?
  • Describe the symptoms and signs you are seeing?
  • What resources would you use?
