Question 1

What is the goal of integrated pest management (IPM)?

Accepted Answer

Balancing pest control with minimal environmental impact

Answer

Integrated Pest Management (IPM) aims to control pest populations using a combination of methods, including biological, cultural, physical, and chemical strategies. The goal is to achieve effective pest control while minimizing risks to human health, beneficial organisms, and the environment.

Question 2

Which factor is essential for healthy plant root development?

Accepted Answer

Adequate oxygen and drainage

Answer

Healthy plant root development relies heavily on adequate oxygen and proper drainage. Roots need oxygen for respiration, and well-drained soil prevents waterlogging, which can suffocate roots and lead to rot, ensuring they can effectively absorb water and nutrients.

Question 3

Why is pruning important in horticulture?

Accepted Answer

It enhances health and structure

Answer

Pruning is essential for enhancing a plant's health and structural integrity. By removing dead, diseased, or overcrowded branches, pruning improves air circulation, light penetration, and redirects energy to stronger growth, promoting overall vigor and often improving flowering or fruiting.

Question 4

Which nutrient primarily supports leaf growth in plants?

Accepted Answer

Nitrogen

Answer

Nitrogen is a primary macronutrient vital for vigorous vegetative growth, particularly in leaves and stems. It is a key component of chlorophyll, essential for photosynthesis, and proteins, which are fundamental for plant structure and function.

Question 5

What is a symptom of fungal plant disease?

Accepted Answer

Leaf spots or powdery mildew

Answer

Fungal plant diseases often manifest with distinct visual symptoms on plant foliage. Common indicators include leaf spots, which are discolored lesions, or powdery mildew, appearing as a white, powdery coating on leaves and stems, both of which can impair plant health.
