What is the primary reason for the control of noxious weeds?

• A. They are beneficial for biodiversity.
• B. Declared by law, they must be controlled.
• C. They only affect certain crops.
• D. They enhance soil fertility.

Answer: (B)

The primary reason for the control of noxious weeds is that they have been declared by law as requiring control measures. This legal classification signifies that noxious weeds pose significant threats to agriculture, natural ecosystems, and public health. The management and eradication of these weeds are mandated because they can outcompete native vegetation, reduce crop yields, and harbor pests and diseases that can further impact agriculture and ecosystems. In contrast to the correct answer, the notion that noxious weeds are beneficial for biodiversity or enhance soil fertility is inaccurate, as these weeds often disrupt ecological balance rather than contribute positively to it. While they may affect certain crops, the legal requirement for their control encompasses a broader range of issues that affect multiple agricultural sectors and the natural environment, thus highlighting the critical need for their management.
