“…Samples were collected during field surveys carried out between March and November 2017 and in May 2018 in the six mango-producing provinces of Burkina Faso: Houet, Kénédougou, Comoé, Sanguié, Nahouri and Sissili (Figure 1) [2]. In 17 localities, 1-2 orchards were sampled.…”

“…Symptoms include dying back of twigs from the top, discolouration and the death of leaves, gummosis from branches, and browning of the vascular tissues when cross-sections were made in diseased mango twigs and main trunks. In the advanced stages of disease, the branches dry up one after the other, leading to partial or total decline of the trees a few months after first symptoms appeared [2].…”

Dieback or decline caused by Lasiodiplodia spp. is a major disease of mango trees (Mangifera indica L.). The main objectives of this study were to identify Lasiodiplodia species associated with mango decline in Burkina Faso, and to asses the climatic and edaphic factors affecting the geographic distribution of the disease in the country. The genetic diversity of 47 Lasiodiplodia isolates was studied based on sequence data of the translation elongation factor 1-alpha gene (tef1-a) and the rDNA internal transcribed spacer region (ITS). Phylogeny analyses grouped the isolates from Burkina Faso with 6 different Lasiodiplodia species, including L. euphorbicola that accounted for 36 of the 47 isolates. Lasiodiplodia isolates tested on mango seedlings induced the typical dieback symptoms. Disease incidence and severity were generally higher in the drier and warmer regions (eastern) of the country. This study provides the required information to establish control strategies against mango decline in Burkina Faso.

Cashew cultivation faces several health problems. Among these problems, anthracnose causes extensive damage to twigs, leaves and fruits and causes loss of yield. The spread of this disease is thought to be determined by certain agromorphological features of the cashew tree. The objective of this study was to search for these agro-morphological determinants that influence the spread of anthracnose disease in agroforestry systems in Côte d'Ivoire. To achieve this objective, 30 cashew trees spread across 26 agroforestry cashew orchards in the Korhogo, Sinématiali and Boundiali departments were chosen and geolocated. The factor studied was the clone, consisting of 30 cashew genotypes, with 15 modalities. The collected data was subjected to descriptive analysis, correlation test, PCA and hierarchical ascending classification (CAH). The results showed that the wingspan, leaf area and size of cashew trees are determinants that promote the spread of anthracnose disease. Following this result, the CAH made it possible to screen the genotypes into three groups. These results could contribute to management of anthracnose disease in agroforestry, to enhance and intensify this cropping systems.

“…Besides, some others fungi species are associated or not with L. theobromae in dieback like Phytophthora citrophthora (Ko et al, 2004). Fusarium oxysporum (Mvondo et al, 2018), Ceratocystis fimbriata (Hassan and Nazzami, 2017;Oliveira et al 2015) Aspergillus niger, Botritis cineria, Curvularia sp, Fusarium sp and Schizosaccharomyces pombe were also isolated from the stem of trees infected by L. theobrome (Dianda et al, 2018;Mvondo et al, 2018).Gummosis are always found in the bark of the stem of several trees attacked. In Cameroon, there is lack of data on the dieback disease.…”
