The nematode identified is Meloidogyne incognita, also known as the root-knot nematode. Key Details:\begin{itemize} \item This nematode targets tobacco plant roots, inducing the formation of distinct root knots or galls. \item These galls impair the root system's integrity, diminishing water and nutrient uptake. \item Infestation results in stunted plant development, wilting, and a substantial reduction in crop yield. \end{itemize} Management Practices:\begin{itemize} \item Implementing crop rotation with non-host species to interrupt the nematode's life cycle. \item Employing nematicides to manage nematode populations. \item Cultivating and utilizing plant varieties resistant to nematode infestation. \end{itemize}% Quick tip
