STANDARD Botany Nematode Infections MCQ Question

Meloidogyne incognita, commonly known as the root-knot nematode, primarily infects the roots of tobacco (Nicotiana tabacum), leading to significant yield reductions due to the formation of galls that disrupt nutrient and water uptake. While nematodes can affect a variety of crops, cotton (Gossypium spp.), corn (Zea mays), and maize (Zea mays) are not the primary hosts for M. incognita, making option C the most accurate choice. Understanding the specific host interactions of plant pathogens is crucial for effective crop management and disease control strategies.
