Abstract:
The presence of Amaranthus spp. Plants showing symptoms caused by root-knot nematode infection were detected in soybean fields from the municipality of Palmitas, Soriano, and Colonia del Sacramento, Colonia - Uruguay. After weed plants collection with root knot nematodes, the causal agents were identified as Meloidogyne incognita and Meloidogyne javanica from their morphology, esterase phenotypes, and species-specific characterized sequence amplified region (SCAR) sequences. The modified version of Koch's postulates was used to confirm the pathogenicity of Meloydogine ssp. In Amaranthus species. Host capacity of Amaranthus species for root-knot nematodes aggravates the harmful potential of the presence of these plants in crop fields. Therefore, control of these weed species, which allow for the reproduction of these parasites, might be an important tool for its management. This is the first report of root-knot nematodes M. incognita parasitizing A. hybridus and A. tuberculatus; and M. javanica parasitizing A. palmeri, A. hybridus and A. tuberculatus in Uruguay. |

ABSTRACT.
Neofusicoccum eucalyptorum is a canker-associated fungus apparently highly specialized on Eucalyptus. However, in surveys of the microbial population inhabiting native Myrtaceae in Uruguay, fungal cultures resembling N. eucalyptorum were isolated. The possible occurrence of N. eucalyptorum on hosts other than Eucalyptus prompted further investigation. Several surveys were conducted throughout Uruguay to obtain samples from native forests, focusing primarily on species in the Myrtaceae. Fungal identification was based on morphology and confirmed using comparison sequences for the internal transcribed spacer (ITS) of the rDNA operon. Pathogenicity was evaluated by inoculating plants of a Eucalyptus grandis clone. Morphological and molecular identification confirmed the occurrence of N. eucalyptorum on Blepharocalyx salicifolius, Myrceugenia glaucescens and Myrrhinium atropurpureum var. octandrum. This is the first report of N. eucalyptorum occurring in hosts other than Eucalyptus. Pathogenicity tests confirmed the ability of this species to produce cankers on E. grandis. This study provides information that will assist breeding programmes in attempts to obtain disease-resistant Eucalyptus plantations and it also suggests that a Eucalyptus pathogen could have moved to native trees in Uruguay.
