This study was carried out within the framework of agricultural biology via the use of extracts (aqueous, acetone and methanol) of <em>Th\u00e9v\u00e9tia peruviana <\/em>seeds in the field and in the laboratory to reduce the development of Sclerotinia sclerotiorum causal agent of sclerotinia of common bean. These diseases mainly affect the leaves of common bean and can completely destroy sensitive cultivars in less than 10 days and cause yield losses of around 50%. As a general objective, it was a question of evaluating the biopesticide effect of Th\u00e9v\u00e9tia peruviana seeds. More specifically, the aim was to evaluate the in vitro and then field effect of extracts of Th\u00e9v\u00e9tia peruviana seeds on the growth, phytosanitary status and yield of common bean. From what results from this work, it appears that methanol extracts have shown a more significant effect than acetone and aqueous extracts in in vitro conditions while in the field acetone extracts have shown themselves to be more effective than methanol and aqueous extracts.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n","protected":false},"featured_media":5208,"template":"","meta":{"_acf_changed":false},"schedule":[5],"speaker-category":[6],"class_list":["post-5207","speaker","type-speaker","status-publish","has-post-thumbnail","hentry","schedule-day-1","speaker-category-speakers"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Abeng Ndmoumou | University of Yaound\u00e9 | Cameroon<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/cognitionconferences.com\/agriculture\/speaker\/abeng-ndmoumou\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Abeng Ndmoumou | University of Yaound\u00e9 | Cameroon\" \/>\n<meta property=\"og:description\" content=\"Abstract We present here in summary a study that was done in Cameroon at the University of Yaound\u00e9 1, Faculty of Sciences more precisely at the Department of Biology and Plant Physiology.
