The high use of glyphosate for weed and pest control of cassava crops in Africa, particularly in Côte d'Ivoire, is correlated with the increasing extent of cassava anthracnose in the cassava producing regions. This health situation raises the question of the existence of a combined effect of glyphosate and anthracnose infection on the defence response of the cassava plant. The study was on the effect of glyphosate on antibiosis in M. esculenta in the pathosystem with C. gloeosporioides. To achieve this objective, a classical fully randomized 3-repeat device was used and antibiosis was the factor studied with 3 modalities. Treatments carried out on the plots, 4 months after planting, were inoculation of test plots of cassava with C. gloeosporoides before they were treated with 4JAI glyphosate. The assessment of phenolic and flavonoid antibiosis levels was carried out on leaf and stem organs harvested from 1JHA to 45 JHA and from the day of glyphosate treatment to 41 JHA. Comparative flavonoid antibiosis profiles were determined by CCM at the stages of maximum inhibition and maximum accumulation. Results showed that the phenolic and flavonoid antibiosis content of plants in glyphosate-treated plots decreased progressively in all varieties studied from JATr 1 to JATr 7. After the seventh day, the respective amounts of phenolic and flavonoid antibiosis gradually increased from the 8th JATr to the 180th JATr. This study showed a negative but partial interference of glyphosate in the defense mechanism of cassava cultivars (Manihot esculenta).

Les auteurs ont étudié l’effet du glyphosate sur les antibioses chez M. esculenta dans le pathosystème avec C. gloeosporioides. Pour atteindre cet objectif, un dispositif classique à trois répétions complètement randomisées a été utilisé et les antibioses sont le facteur étudié avec 3 modalités. Les traitements réalisés sur les parcelles, 4 mois après plant plantation, ont été l’inoculation des parcelles tests de manioc par C. gloeosporoides avant que celles-ci ne soient traitées par le glyphosate 4JAI. L’évaluation des teneurs en antibioses phénoliques et flavonoïdiques a été réalisée sur les organes feuilles et tiges récoltées de 1JAI à 45 JAI et du jour du traitement au glyphosate à 41 JAT. Les profils comparatifs en antibioses flavonoïdiques ont été déterminés par CCM aux stades de l’inhibition maximale et de l’accumulation maximale. Les résultats ont montré que la teneur en antibioses phénoliques et flavonoïdiques des plantes des parcelles traitées avec le glyphosate ont diminué progressivement chez toutes les variétés étudiées du 1er JATr au 7ème JATr. Après le septième jour, les quantités respectives des antibioses phénoliques et de flavonoïdes ont augmenté progressivement du 8ème JATr au 180ème JATr. Il ressort de cette étude, une interférence négative mais partielle du glyphosate dans le mécanisme de défense des cultivars de manioc (Manihot esculenta).

In order to assess both the level of botanical knowledge of the shea tree species possessed by certain communities, and the relative importance of the species to those communities, an inventory has been taken of the different uses of shea resources. To this end, research was conducted involving 257 people belonging to 12 different ethnic groups in seven departments of the north of the Cote d'Ivoire [Ivory Coast]. The results of these investigations clearly demonstrate the socioeconomic importance of shea trees to the local populations of the zone investigated. Some ethnic groups prove to have a very good botanical knowledge of the species and its qualities and have developed systems of management of shea orchards that could facilitate the domestication and conservation of the species. In addition to the commercial use of the kernel and of shea butter on local and regional markets, many other parts of the shea tree and derived products (roots, leaves, peels, oilcakes, latexes and even mistletoes are used for a range of different purposes by rural communities in Cote d’Ivoire [the Ivory Coast]. In medicine and in traditional pharmacopeia, these parts are used in the treatment of several diseases. Shea is also valued at the cultural, nutritional, agricultural, cosmetic, artisanal level.
