| Popis: | Eight root-knot nematode forms are known to occur in Brazil, namely Meloidogyne exigua, M. incognita, M. j. javanica, M. j. bauruensis, M. inornata, M. hapla, M. arenaria arenaria and M. coffeicola. After presenting a historical resume of the root-knot disease, as well as observations on symptoms, distribution and spread, and life history of the nematodes, a study of the morphological characters used in identification of species is made, a key for separating the forms referred to above being also prepared. As no information on host plants of the coffee root-knot nematode (M. exigua) was available, a few tests were performed, as an attempt to infect several plant species. Pepper (Capsicum annuun) was the only plant attacked by M. exigua, having failed all attempts to infect nine other plants, including tomato var. Rutgers. M. exigua incited formation of galls on roots of cucumber, but no adult female was found in the tissue. In a final chapter dealing with control, a review of all methods available is presented. |
