ORBi Open Repository and Bibliography
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

SURVEY OF RICE DISEASES IN THREE REGIONS IN MADAGASCAR - Mamiharisoa Razanakoto, Léa; De Clerck, Caroline; Zalmine, Francia; Rabemanantsoa, Christian; El Jaziri, Mondher; Jijakli, Haissam
Rice (Oryza sativa) is the most cultivated crop and the staple food in Madagascar. However, the country has never achieved food self-sufficiency and continues to import rice abroad. Rice diseases are one of the factors limiting rice production and causing significant yield reductions.
Our study aims to identify the rice pathogens present in three region of Madagascar: two of these regions (Analamanga and Vakinankaratra) are located in upland region when the last (Atsinanana) is located in coastal regions. Fifty five (55) rice samples were collected and cultured on standard media. A survey questionnaire was also conducted with the farmers in order...
Sreening of essential oils against rice pathogens isolated from Madagascar - Mamiharisoa Razanakoto, Léa; De Clerck, Caroline; Massart, Sébastien; Rabemanantsoa, Christian; El Jaziri, Mondher; Rakotozandrindrainy, Raphaël; Jijakli, Haissam
Four predominant isolated pathogens have been identified during survey of rice diseases in three regions in Madagascar. These pathogens were the bacteria Xanthomonas oryzae pv. oryzae and Pseudomonas fuscovaginae and the fungi Alternaria sp. and Curvularia lunata. These pathogens are causing significant yield reduction on rice, which is the staple food in this country. After the identification of those pathogens, the objective of this work was to identify appropriate control measures against them.
Plants extracts has been traditionally used to control diseases in other plant species. Nowadays, the problem of residues of phytopharmaceutical product, reinforce the need for research on the...
