【 摘 要 】

Root-knot of tomato plants, caused by Meloidogyne incognita, is one of the most important diseases of vegetables in Ivory Coast. This study is a contribution to improving the production of small producers by seeking simple and replicable methods. To do so, soil infested by M. incognita was treated with ricin extract, cow dung and nematicide (carbofuran), alone or in combination. The treatments reduced galls and tomato plants leaf symptoms after 45 days, compared to the control (no treatment). The treatments with cow dung + nematicide and ricin extract + nematicide were most effective (disease incidence = 0 %). Furthermore, in addition to its nematicidal action, the ricin extract has a promoting action of tomato plants growth.
