Question

(i) Name the nematode (scientific name) that infects the roots of tobacco plant and reduces its yield.

Hint:

Meloidogyne incognita causes root knot disease, significantly reducing crop yield.

Answer 1

The nematode is Meloidogyne incognita, commonly known as the root-knot nematode. Key Details: \begin{itemize} \item It infects the roots of tobacco plants, causing the formation of characteristic root knots or galls. \item These galls disrupt the root structure, leading to reduced water and nutrient absorption. \item Infected plants exhibit stunted growth, wilting, and significantly reduced yields. \end{itemize} Management Practices: \begin{itemize} \item Crop rotation with non-host plants to break the nematode life cycle. \item Application of nematicides to control nematode populations. \item Development and use of nematode-resistant plant varieties. \end{itemize} % Quick tip
