Tree Gummosis a Thread for Mango Production in Northern Senegal
Authors(4) :-N. Mbaye, G. F. A. Manga, P. M. Diedhiou, P. I. Samb In Senegal mango is one of the most important fruit crops. Mango trees are planted in a large part of the territory and produced in different cropping systems. Setting up mango orchards represents a great contribution to the national production effort. However, infestations of the vegetative organs of the trees by diseases, in addition to fruits infestations, are a major constraint to the development of mango plantations. The identification of the causal agents for any disease is a prerequisite for corrective actions. In the Lampsar orchard, an outbreak of gummosis was observed in almost all plots of mango trees, with greater intensity in the lower parts of the field. However a variety of symptoms was recorded. Some plants showed cracking of the stem bark and gum exudation (gummosis), while others, exhibited only the cracking of the stem bark. The symptoms were most frequently located below the grafting point and/or on the junction point of the graft and the rootstock. The incidence of the disease varied from a plot to the other, ranging from 0.59% to 8.5%. The diagnosis, made for 30 fungal isolates obtained from samples collected in the field, allowed identifying Lasiodiplodia sp as a causal agent, thanks to the presence of its characteristic pycnidia and pycniospores. Recommendations were made for the control of this fungus in the orchard.
