✅Explanation: In cotton, the wilt disease caused by the fungus Fusarium oxysporum f. sp. vasinfectum (FOV) is often more severe in the presence of root-knot nematodes (Meloidogyne spp.). Root-knot nematodes damage the roots of cotton plants, creating wounds that facilitate the entry of the FOV fungus. Furthermore, the nematodes can weaken the plant's defenses, making it more susceptible to infection.
