The pest survey was used, preceded by one month of a pre-survey in North Kabare. In addition, the method of direct and detailed observation, systematic sampling and identification key was used. The aim of this study is to know the culture system and to assess the impact and severity of the disease raging coffee (Coffea arabica). The study shows that the cropping system as practiced is associated coffee and the majority of Kabare Northern coffee plantations suffer of Anthracnose, the rust and leaf spot thus fungal diseases. Coffee trees suffering with Die back, their branches, sometimes their branches, black and dry out gradually from the end and lose leaves, those of Anthracnose, green drupes growth appear small dark brown spots, black, rounded oval, markedly depressed that expand quickly. For rust, small yellow circular spots appear on the underside of leaves and leaf spot, small chlorotic points that extend and turn brown.

Abstract
The pest survey was used, preceded by one month of a pre-survey in North Kabare. In addition, the method of direct and detailed observation, systematic sampling and identification key was used. The aim of this study is to know the culture system and to assess the impact and severity of the disease raging coffee (Coffea arabica). The study shows that the cropping system as practiced is associated coffee and the majority of Kabare Northern coffee plantations suffer of Anthracnose, the rust and leaf spot thus fungal diseases. Coffee trees suffering with Die back, their branches, sometimes their branches, black and dry out gradually from the end and lose leaves, those of Anthracnose, green drupes growth appear small dark brown spots, black, rounded oval, markedly depressed that expand quickly. For rust, small yellow circular spots appear on the underside of leaves and leaf spot, small chlorotic points that extend and turn brown.
Author Keywords: Anthracnose, rust, leaf spot, Die back, branches, chlorotic.
Abstract: (french)
L'enquête phytosanitaire a été utilisée, précédée d'une pré-enquête d'un mois, conduite dans les groupements de Kabare Nord. De plus, la méthode d'observation directe et détaillée, l'échantillonnage systématique ainsi que la clé d'identification ont été utilisées et l'objet de cette étude est de connaitre le système de culture et d'évaluer l'incidence et la sévérité des maladies sévissant les cafiéirs (Coffea arabica). L'étude montre que le système de culturale le plus pratiqué est les caféiers associés et la majorité des plantations des caféiers de Kabare Nord souffrent de l'Anthracnose,de la Rouille et la Cercosporiose donc de maladies cryptogamiques. Les caféiers atteintent par Die back, leurs rameaux, parfois leurs branches, noircissent et se dessèchent progressivement depuis l'extrêmité et perdent les feuilles,ceux d' Anthracnose,les drupes vertes en croissance apparaissent de petites taches brun foncé, à noires, arrondies à ovales, nettement déprimées qui s'étendent rapidement. Pour la Rouille, les petites taches circulaires jaunâtres apparaissent à la face inférieure des feuilles et pour la Cercosporiose, les petits points chlorotiques qui s'étendent et brunissent.
Author Keywords: Anthracnose, Rouille, Cercosporiose, Die back, rameaux, chlorotiques.
