Argentina weeds phytophagous nematodes management Argentina malezas nematodos fitófagos manejo Weeds in general are directly responsible for serious damage in agriculture. Indirectly, they can be hosts and transmit a large number of phytopathogenous organisms. Among these, certain phytophagous nematodes are very important. They find numerous weed species that offer them the possibility of remaining in the soil, affecting its sanitary conditions and crop yields. For the first time in Argentina, a comprehensive study of the nematodes-weed relationships was made. Fourteen valid phytophagous nematode species and two non-identified ones were detected associated with weeds. Three nematode genera that have very dangerous species (Ditylenchus, Meloidogyne, and Nacobbus) are characterized by their association with many weeds. A large variety of weeds (forty-five valid species and nine non-identified ones) that have a wide distribution in the cultivated area of the country are associated with one or more phytophagous nematode species. Gramineae and Compositae are the most important families. Las malezas, en general, además de ser causa directa de perjuicios para la agricultura, son capaces de hospedar y transmitir numerosos fitopatógenos. Entre estos, los nematodos fitófagos ocupan un lugar destacado; encuentran en numerosas especies de malezas la posibilidad de perdurar en el espacio y en el tiempo, comprometiendo seriamente la sanidad de los suelos y la productividad de los cultivos. En Argentina, por primera vez se lleva a cabo un estudio de situación global acerca de las asociaciones nematodos-malezas. Catorce especies válidas y dos especies no identificadas de nematodos fitófagos han sido detectadas asociadas a malezas. Tres géneros de nematodos que comprenden especies muy dañinas para numerosos cultivos (Ditylenchus, Meloidogyne y Nacobbus) se caracterizan por su asociación con numerosas malezas. Una considerable variedad de malezas (cuarenta y cinco especies válidas y nueve especies no identificadas) —de amplia distribución en el área cultivada del país— aparecen asociadas con una o más especies de nematodos fitófagos.

| description |
Weeds in general are directly responsible for serious damage in agriculture. Indirectly, they can be hosts and transmit a large number of phytopathogenous organisms. Among these, certain phytophagous nematodes are very important. They find numerous weed species that offer them the possibility of remaining in the soil, affecting its sanitary conditions and crop yields. For the first time in Argentina, a comprehensive study of the nematodes-weed relationships was made. Fourteen valid phytophagous nematode species and two non-identified ones were detected associated with weeds. Three nematode genera that have very dangerous species (Ditylenchus, Meloidogyne, and Nacobbus) are characterized by their association with many weeds. A large variety of weeds (forty-five valid species and nine non-identified ones) that have a wide distribution in the cultivated area of the country are associated with one or more phytophagous nematode species. Gramineae and Compositae are the most important families. |
