“…El manejo de este nematodo es más difícil en comparación con otras plagas porque viven en el suelo y atacan las raíces de las aliáceas. Por ello, están directamente asociados a las raíces y el suelo (Faruk, 2019), posicionándose como una de las principales amenazas para la producción mundial de estos cultivos y causan pérdidas considerables (Nimgarri et al, 2023). Por ende, se le considera un género destructivo, con efectos devastadores y es más frecuente donde las temperaturas oscilan entre 18 y 27 °C, desde regiones templadas a tropicales del mundo (Rawal, 2020).…”

Alliaceae crops includes several species of agricultural importance for the Arequipa region, among them the onion is the most produced in the country, however, these crops are affected by phytoparasitic nematodes, including Meloidogyne spp. which causes significant losses in the yield. The aim of the present study was to characterise the root-knot nematode (Meloidogyne spp) and determine the population density of phytoparasitic nematodes in alliaceae crops in the main producing localities of the Arequipa region. Samples of roots and soil were collected in onion, chinese onion, leek and chives crops in the provinces of Arequipa, Castilla, Caylloma and Islay. The identification of nematode genus was found by morphological characteristics and the characterization of Meloidogyne were performed by perineal patterns and electrophoretic pattern of esterase (Est). In the 38 soil samples, different genus of plant-parasitic nematodes was found: Aphelenchus, Dorylaimus, Helicotylenchus, Hemicycliophora, Meloidogyne, Mesocriconema, Mononchus, OGMA, Pratylenchus, Rotylenchus, Tylenchus, Xiphinema and free-living nematodes, in root samples, eight populations of Meloidogyne spp. were found. distributed among three species: (1) M. incognita phenotype Est I1, Rm: 1.0 with 33.33% of frequency and Est I2, Rm: 1.03, 1.07 (50%); (2) M. javanica Est J3, Rm: 1.03, 1.24, 1.37 (16.67%) and an atypical species named Meloidogyne sp. Rm: 0.85 (33.33%). The identification of genus and species phytoparasitic nematodes in alliaceae will allow the adoption of more efficient integrated management measures, because have a distinct parasitism behavior.

Cucumber (Cucumis sativus L.) is a valued vegetable crop produced on a large scale throughout the year in a protected cultivation system. Its growth, development, and production are best in well-drained, fertile soil with 6.5 to 7.5 pH. Due to minor crop rotation and monoculture in protected structures, they are severely attacked by soil-borne pathogens. Between them, root-knot nematodes (Meloidogyne spp.) are the most intractable root endo-parasites that cause dramatic damage and severe crop yield losses. Environmental conditions of protected structures favor root-knot disease incidence and development. The non-availability of resistant crops, biological agents, and technology limitations are the key obstacles to their control. Therefore, agrochemicals are the only reliable method of root-knot disease management. In the present investigation, available nematicides (abamectin, metham sodium, fluopyram, and phorate 5G) were engaged in randomized block design with four replications at naturally infested farmer polyhouse (626.66 J2/ 200 cc soil) located at Mirwais Mina area of Kandahar city. Data on disease incidence, disease severity, soil nematode population, and fruit yield of cucumber were recorded 45 days after sowing the seed and at the termination of the field. All the data were statically analyzed using SPSS software (v.24.0.0). Among the treatments, metham sodium was found superior on plant and nematode parameters, followed by fluopyram. About 3.23 kg yield/plant loss was recorded caused by root-knot nematodes in protected cultivation systems. Based on findings, rotating fumigant and non-fumigant nematicides could be a reliable management method in a highly infested commercial protected structure.
