Integrated Management Strategies for Root-knot Nematode (Meloidogyne incognita) in Mulberry Cultivation
Résumé
Mulberry (Morus spp.) is a perennial crop of prime importance in sericulture, serving as the exclusive food source for the silkworm (Bombyx mori L.). The productivity and quality of mulberry leaves directly influence cocoon yield and silk quality. However, root-knot nematodes (Meloidogyne spp.) have emerged as one of the most damaging soil-borne pathogens affecting mulberry cultivation. These obligate parasites induce root galling, disrupt vascular functions and impair water and nutrient uptake, leading to stunted growth, chlorosis, reduced leaf yield and poor cocoon quality. Management of these nematodes is challenging due to their subterranean nature and the limitations of conventional control measures. While chemical nematicides offer short-term control, they pose environmental and health risks. This review focuses on the integrated management of root-knot nematodes in mulberry, emphasizing a combination of cultural practices, organic amendments, botanicals, biological control agents, and resistant varieties. Such integrated approaches not only reduce nematode populations but also enhance plant vigor, improve soil health, and support sustainable sericulture.
