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 to collect information about the context in which the diseases appeared. Micro-organisms isolated were identified by morphological characteristics for fungi, gram stain and anaerobic growth test for bacteria. In addition, molecular DNA characterization was performed by PCR using universal primers for both fungi and bacteria. The amplicons obtained were sequenced and analyzed by BLAST. In Analamanga and Vakinankaratra, Alternaria sp. and Xanthomonas oryzae pv. oryzae were pre-dominant. In the Atsinanana region, however, Curvularia lunata and Pseudomonas fuscovaginae were the most present. The weather in upland regions is indeed warm and humid in summer, dry and cold in winter which favours Xanthomonas oryzae pv. oryzae and Alternaria sp.growth. Moreover, irrigation is practiced in those regions which can explain the spread of the diseases. The weather in coastal region is warm and humid all year long which tend to favor weed development all year, serving as alternative hosts for Pseudomonas fuscovaginae and Curvularia lunata in interseason.

Jatropha curcas L. seed oil is proven to be toxic to many microorganisms, insects and animals. Despite its toxicity, Jatropha is not pest and disease resistant. The following major pests and diseases affecting Jatropha in the lower valley of the Senegal river have been identified: the leaf miner Stomphastis thraustica (Meyrick, 1908) (Lepidoptera, Gracillariidae), the leaf and stem miner Pempelia morosalis (Saalmuller, 1880) (Lepidoptera, Pyralidae) and the shield-backed bug Calidea panaethiopica (Kirkaldy, 1909) (Heteroptera, Scutelleridae), which can cause flower and fruit abortion. Damage from these pests was particularly great during the second year after the plantations were set up (2009) and before later receding. Nevertheless, the worst attacks were caused by a vascular disease transmitted through the soil, which killed 65% of the plants in four years. It is mainly characterised by collar and root rot, which causes foliage to yellow and wilt, before the plant eventually dies. These threats should increase if larger areas are planted with Jatropha. Considering the scale of the damage caused by these attacks in Bokhol, the development of an integrated pest management programme adapted to the local context should be considered. [less ▲]
