Which nematode is known for causing damage primarily to roots of carrots?

• A. Root knot nematode
• B. Stubby root nematode
• C. Needle nematode
• D. All of the above

Answer: (D)

The question addresses nematodes that cause damage to the roots of carrots, and the correct answer is that all of the listed nematodes can be responsible for such damage. The root knot nematode is known to form galls or "knots" on the roots of carrot plants, which can severely affect nutrient and water uptake. This leads to stunted growth and reduced yield. The stubby root nematode affects the root systems similarly, causing a shortened and stubby appearance in the roots, which can significantly impact the plant’s health and ability to absorb water and nutrients. The needle nematode primarily feeds on root tips, leading to root necrosis and hindering root growth, consequently leading to decreased vigor and productivity of the carrot plants. Understanding the impact of these nematodes is crucial for managing root health in carrot cultivation, making it important to recognize that each of these nematodes can contribute to the overall damage observed in carrots.
