Situation de la cercosporiose noire des bananiers et plantains Musa spp. sous différents systèmes de culture à Yangambi, Haut-Zaïre

Abstract

Black sigatoka situation of bananas and plantains Musa spp. under different farming systems at Yangambi, Upper-Zaire. Black sigatoka, a leaf spot disease, caused by Mycosphaerella fijiensis Morelet seems to be one of the major constraints in the banana and plantain production in Upper-Zaire. Indeed, a survey study undertaken at Yangambi on 12 plantain and 4 banana cultivars revealed that all the observed cultivars were attacked with an exception of banana "Yangambikm 5" which was tolerant. In otherhand, significant differences were observed between bananas and plantains cultivated in fields and those planted in backyards. The regular application of organic matter in backyard farms seems to be one of the major reasons of those differences.
