dc.description.abstractThe 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).en_US
