What are noxious weeds?

• A. Weeds that are beneficial for the ecosystem
• B. Plants that are particularly troublesome and undesirable
• C. Weeds that produce valuable crops
• D. Plants that grow well in poor soil

Answer: (B)

Noxious weeds are defined as plants that are troublesome and undesirable, typically causing harm to crops, ecosystems, or human health. They can outcompete native vegetation and agricultural crops for resources such as light, water, and nutrients. This aggressive growth can lead to reduced crop yields, increased management costs, and negative impacts on biodiversity. Understanding the significance of noxious weeds is crucial for effective management, particularly in agricultural and natural settings, to maintain healthy ecosystems and promote agricultural productivity. Recognizing such weeds enables the implementation of targeted control measures and helps protect valuable resources.
