How can marigolds help in pest control?

• A. They act as plants that repel insects
• B. They attract more pests
• C. They act as a food source for pests
• D. They are used as compost material

Answer: (A)

Marigolds are known for their pest-repelling properties, making them beneficial in pest control. These flowers release specific compounds and chemicals into the soil and air that deter various garden pests, including nematodes, aphids, and whiteflies. By planting marigolds in or around vegetable gardens and flower beds, gardeners can create a natural barrier that helps protect more vulnerable plants from insect damage. This natural pest resistance aids in reducing the need for chemical pesticides, promoting a healthier and more sustainable gardening practice.
