Question

Which nematode is known for causing 'root-knot' disease in plants?

• A. Heterodera avenae
• B. Meloidogyne incognita
• C. Pratylenchus penetrans
• D. Ditylenchus dipsaci

Hint:

Root-knot nematode = Meloidogyne incognita.

Answer 1

The Correct Option is B

Meloidogyne incognita, commonly known as the root-knot nematode, is a plant-parasitic nematode that induces the formation of characteristic galls or "knots" on the roots of infected plants. These galls interfere with the plant's ability to absorb water and nutrients, leading to stunted growth and yield losses. Management includes crop rotation, resistant varieties, and nematicides.
