Biology, Taxonomy, and Management of the Root-Knot Nematode (Meloidogyne incognita) in Sweet Potato

Sweet potato is the seventh-ranked food crop produced after wheat, rice, maize, potato, barley, and cassava in world. It most important root tuber temperate, subtropical, tropical areas of grown for food, income-generating, jobs farmers retailers. The nutritional substances sweet potatoes are ß-carotene anthocyanins. However, production its valuable products limited due to root-knot nematode parasitism. One destructive species this Meloidogyne incognita. stage at second juvenile (J2). At stage, it invades roots tubers highly warm sandy soil conditions. an obligate plant-parasitic nematode. M. incognita caused significant yield loss terms quality, quantity, disturbing process photosynthesis nutrient uptake through formation galling, establishing feeding sites, or induced galls that contain giant-feeding cells, cracking directly. also reduces market values infected by downgrading values. problem quality quantity losses pest one major problems nowadays. alone interaction with other pathogens synergistic fungi, bacteria, viruses, others. Therefore, review paper focused on biology, taxonomy, geographical distribution, management measures.
