A. Classify each observation as either pest damage or disease symptoms. b. Recommend 2 environmentally friendly control methods. c. Explain why every infected leaf should be uprooted and destroyed.

a)

1. Wilting Plants: This is a disease symptom.
2. Brown spot on the leaves: This is a disease symptom.

b)
Two environmentally friendly control methods are:

1. Biological control: Using natural enemies (predators, parasites, or pathogens) to control pests.
2. Crop rotation: Alternating the type of crop grown in a specific area over successive seasons to disrupt pest and disease cycles.

c)
Every infected crop should be uprooted and destroyed to prevent the spread of the disease or pest to healthy plants. This practice helps to remove the source of infection (pathogen or pest) from the field, reducing the overall inoculum load and breaking the disease cycle, thereby protecting future crops.
