The survey carrying on the effect of the cultural practices in the struggle against the bacterial withering of the banana tree (wilt) in Kadjucu South Kivu area has been led during fifteen months in order to value the effects of the ablation of the male inflorescence, the unstamped and the cut of the sick stumps while using the disinfected materials. For that, we considered three impacts of which 5 to 10%, 11 to 15%, more than 20% and three witnesses of which one for every impact. And the duration of propagation of Banana Xanthomonas wilt in field has been valued. The results show us that the cultural practices are efficient if the illness is again in the beginning. So one can manage the bacterial withering of the banana plants by the cultural practices if the impact is lower to 20%, but if the rate of attack is raised more it is recommended to practice the rotation of the cultures. The duration of propagation of Banana xanthomonas wilt between two banana trees on a same stump is of vicinity two months and a half. Therefore these results show that this illness cannot be eradicated by these cultural practices. It is recommended to suppress the sources of inoculums and to eliminate the risks of dissemination in the fields which are not reached.

Abstract

For that, we considered three impacts of which 5 to 10%, 11 to 15%, more than 20% and three witnesses of which one for every impact. And the duration of propagation of Banana Xanthomonas wilt in field has been valued. The results show us that the cultural practices are efficient if the illness is again in the beginning. So one can manage the bacterial withering of the banana plants by the cultural practices if the impact is lower to 20%, but if the rate of attack is raised more it is recommended to practice the rotation of the cultures. The duration of propagation of Banana xanthomonas wilt between two banana trees on a same stump is of vicinity two months and a half. Therefore these results show that this illness cannot be eradicated by these cultural practices. It is recommended to suppress the sources of inoculums and to eliminate the risks of dissemination in the fields which are not reached.

Abstract: (french)
L'étude de l'effet des pratiques culturales dans la lutte contre le flétrissement bactérien du bananier (wilt) à Kadjucu, Sud Kivu a été menée pendant quinze mois afin d'évaluer les effets de l'ablation des inflorescences mâles, du dessouchage et de la coupe des plants et des souches malades à l'aide des matériels désinfectés. Pour y parvenir, trois incidences de Banana xanthomonas wilt ont été considérées dans les bananeraies attaquées dont 5 à 10%, 11 à 15%, plus de 20% et trois témoins dont un pour chaque incidence. Et la durée de propagation de cette bactériose dans les différentes parcelles a été évaluée. Les résultats montrent que ces pratiques culturales sont efficaces si la maladie est encore au début. Ainsi on peut gérer le flétrissement bactérien du bananier par les pratiques culturales si son incidence dans les bananeraies est inférieure à 20% mais si le taux d'attaque est plus élevé il est recommandé de pratiquer la rotation des cultures. La durée de propagation de la maladie entre deux plants sur une même souche est d'environs deux mois et demi. Toute fois ces résultats montrent que cette maladie ne peut pas être éradiquée par ces techniques culturales. Il est recommandé de supprimer les sources d'inoculum et éliminer les risques de dissémination dans les champs non encore atteints.
