Abstract


The survey carrying on the struggle against the bacterial wilt of the potato has been led between November 2012 and February 2013 on the Penap variety in the perspective to defend Solanum tuberosum against the aggressions of Pseudomonas solanacearum and to valorize thus potentialities them bactericidal and insecticide that offer Tephrosia vogelii and Nicotiana tabacum. To the results gotten it has been established that the use of the excerpts of T. vogelii about 200g leaves in one liter of water on the potatoes during one month stop not only the propagation of the illness but also increase the vigor and is important to prolong the longevity of the plantations reached. As for the use of N. tabacum in the treatment of the bacterial withering of the only potato, its mechanical effect against the vector has been found. The association of two plants however was a factor to high risk for the potatoes.

Author Keywords: Bacterial withering, aqueous excerpts, potato, Pseudomonas solanacearum, Tephrosia vogelii and Nicotiana tabacum.


Abstract: (french)


L'étude portant sur la lutte contre Pseudomonas solanacearum agent du flétrissement bactérien de la pomme de terre a été menée entre Novembre 2012 et Février 2013 sur la variété Penap dans la perspective de défendre Solanum tuberosum contre les agressions de P. solanacearum et valoriser ainsi les potentialités bactéricides et insecticides qu'offrent Tephrosia vogelii et Nicotiana tabacum. A l'issu des résultats obtenus il a été établi que l'utilisation des extraits de T. vogelii en raison de 200g des feuilles dans un litre d'eau sur les pommes de terre pendant un mois peut non seulement arrêter la propagation de la maladie mais aussi augmenter la vigueur et prolonger la longévité des plants atteint dans un champ. Quant à l'utilisation de N. tabacum dans le traitement du flétrissement bactérien de la pomme de terre seul son effet mécanique contre le vecteur a été trouvé cependant l'association de deux plantes a été un facteur à haut risque pour les pommes de terre.
