“…Although BLSD's effect on fruit ripening has been widely documented, this is the first report of BLSD's effect on banana susceptibility to crown rot disease. This result confirms previous observations suggesting that some biotic factors had a potential effect on banana susceptibility to crown rot [18].…”

“…Three hours after inoculation, clusters of the same treatment were packed in perforated plastic bags and in commercial boxes. They were stored under stable conditions at 13°C for 13 days [18]. At the end of this storage period, an evaluation of the internal progression of the rot within the crown was made.…”

“…However, a study recently carried out in some localities in Cameroon has highlighted a potential effect of black leaf streak disease (BLSD) on banana susceptibility to crown rot [18]. BLSD and Sigatoka disease (SD) of bananas are foliar diseases caused, respectively, by the ascomycetous fungi Mycosphaerella fijiensis and M. musicola.…”

“…Unfortunately, little is known about pre-harvest factors, which influence the post-harvest development of crown rot disease in bananas. Although pedo-climatic conditions and agro-technical factors are known to influence the development of this disease [15][16][17], only very few studies link such fluctuations to either fruit susceptibility [6,10,18] or to fruit contamination.…”

-Introduction. The susceptibility of banana fruit to crown rot and anthracnose, the two main banana post-harvest diseases, is influenced by many pre-harvest abiotic factors. Mycosphaerella leaf spot diseases (MLSD) of bananas are biotic pre-harvest factors, which have an influence on fruit physiology. The fruit's susceptibility to post-harvest diseases may also be influenced by foliar diseases caused by M. fijiensis, responsible for black leaf streak disease (BLSD), and M. musicola, which causes sigatoka disease (SD). The aim of our study was to determine the influence of these biotic pre-harvest factors on banana fruit's susceptibility to crown rot and anthracnose. Materials and methods. A disease severity gradient was established in two experimental fields (Cameroon for BLSD and Guadeloupe for SD) where, at the flowering stage, six different levels of MLSD severity were selected. Fruit susceptibility was determined through necrotic surface assessments after artificial inoculation by Colletotrichum musae on the 3rd hand of harvested bunches. Results and discussion. BLSD significantly influenced banana sensitivity to crown rot (P < 0.001) but only had a slight effect on the development of anthracnose (P = 0.041). SD had no effect (P > 0.05) on banana susceptibility to either post-harvest disease. These results are discussed with emphasis on the influence of variations in the source-sink ratio on fruit physiology. The influence of BLSD on crown rot disease suggests the need to take into account the management of these foliar diseases for an alternative control method of post-harvest diseases through integrated pest management programs.Cameroon / Guadeloupe / Musa / fruits / Mycosphaerella fijiensis / Mycosphaerella musicola / black sigatoka / black leaf streak disease / anthracnoses / crown rots Impact de l'extension de la maladie des raies noires sur la sensibilité des bananes aux maladies post-récolte.Résumé -Introduction. La sensibilité des bananes aux maladies post-récolte (pourriture de couronnes et anthracnose) est influencée par plusieurs facteurs abiotiques pré-récolte. Les maladies foliaires de bananes sont des facteurs biotiques pré-récolte causés par Mycosphaerella fijiensis pour la maladie des raies noires (MRN) et M. musicola, pour la maladie de Sigatoka (MS). Ces maladies foliaires pourraient avoir une influence sur la physiologie du fruit. L'objectif de cette étude a été de déterminer l'influence de ces facteurs biotiques pré-récolte sur la sensibilité du fruit à la pourriture de couronnes et à l'anthracnose. Matériel et méthodes. Un gradient de sévérité de la maladie a été établi dans deux parcelles expérimentales (Cameroun pour la MRN et Guadeloupe pour MS). À la floraison, six niveaux différents de sévérité de ces maladies foliaires ont été sélectionnés.

“…Nevertheless, no differences in pathogen development were observed in either of the two harvest years evaluated for fruits grouped by their ripening time (early, middle, or late) (Table 4). Ewané et al (2013) founded that susceptibility to anthracnose of banana fruits is not influenced by the harvest season (dry or rainy). However, to our knowledge, no studies on the correlation between Table 3 Effect of maturity stage on severity (lesion diameter and area) of P. expansum in 10 apple genotypes harvested in 2011 and stored at 26 • C for 8 days.…”
