Evaluation of the 19 varieties and accessions of tomato against bacterial wilt in Bobo-Dioulasso, Burkina Faso

Bacterial wilt caused by Ralstonia solanacearum E. F. Smith is one of the most harmful phytobacteriosis in the world. The search for varieties resistant or tolerant to this disease is the main method of control. However, there is very little information on tomato accessions and varieties deemed resistant or tolerant to the disease in Burkina Faso, hence the resistance assessment of 19 tomato varieties and accessions in the field in order to improve the productivity of tomatoes in Burkina Faso. With respect to varietal screening, a completely randomized Fisher block was used and agromorphological parameters were evaluated. The evaluation has shown that CRA 66, F1 Platinum, NC72TR4-4, Hawaii 7996, BF-Okitsu and FBT4 are more resistant with respective incidences of 1.25%; 1.25; 1.47%; 2.50%; 2.95% and 4.37%; while L390 was the most sensitive (38.80%). In terms of production, F1 Platinum, F1 Mongal, FBT3 and FBT4 gave the best net yields of 25.85; 25.47; 20.6 and 20.34 tonnes.ha-1. On the other hand, some accessions (CRA66 and BF-Okitsu), which are less sensitive to the pathogen, gave derisory yields. In view of the results obtained, market gardeners in the city of Bobo-Dioulasso can be advised of INERA varieties FBT3 and FBT4 and the F1 Platinum and F1 Mongal hybrids for their good behavior in terms of resistance to the disease and/or of correct yield in infected soils.Keywords: Burkina Faso, R. solanacearum, tomato, varietal resistanc

Usage thérapeutique du manguier (Mangifera indica L., Anacardiaceae) au Burkina Faso

Les extraits d’organes de manguier (Mangifera indica L., Anacardiacaea) présentent un potentiel d’utilisation dans des applications pharmaceutiques. Le but de cette étude est de contribuer à une meilleure connaissance des vertus thérapeutiques du manguier au Burkina Faso. Des enquêtes ethnobotaniques ont été réalisées à l’aide de questionnaire auprès des phytothérapeutes de trois régions du Burkina Faso (Centre-Ouest, Hauts-Bassins et Cascades). Les résultats ont été obtenus auprès de 45 phytothérapeutes enquêtés. Ces phytothérapeutes sont représentés par 79% d’hommes et 21% de femmes. La tranche d’âge comprise entre 31 et 40 ans est la plus représentée, soit 32,41% et 59,25% des phytothérapeutes enquêté sont non scolarisés. Les résultats obtenus ont permis de répertorier des maladies couramment traitées avec les organes du manguier. De plus, les feuilles du manguier des variétés ordinaires (Mangot vert et sabre) surtout sont les plus utilisées dans la préparation médicamenteuse. La décoction est le mode de préparation le plus sollicité et l’administration des remèdes se fait par voie orale (100%). Une étude pharmacologique devrait permettre l’incorporation des extraits des organes du manguier dans des compléments alimentaires pour traiter certaines maladies.Mango (Mangifera indica L., Anacardiacaea) organ extracts have potential use in pharmaceutical applications. The aim of this study is to contribute to a better knowledge of mango health benefits in Burkina Faso.

The results were obtained from 45 herbalists surveyed. These herbalists are represented by 79% men and 21% women. The age group between 31 and 40 years is the most represented, i.e. 32.41%, and 59.25% of the herbalists surveyed are illiterate. The results obtained made it possible to list the diseases commonly treated with mango organs. Moreover, mango leaves of the ordinary varieties (green mango and saber) are the most used in the preparation of medicines. Decoction is the most popular method of preparation and the remedies are administered by oral route (100%). A pharmacological study should make it possible to incorporate extracts of mango organs into food supplements to treat diseases
