Occurrence of Fungal Diseases and Their Importance on Date Palm in Sudan
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 5
Abstract
Date palm (Phoenix dactylifera L.) is an important fruit tree in north of Sudan and it was observed to be severely affected by many diseases. This study was carried out to evaluate the incidence and distribution of fungal diseases in date palm in its main producing areas in north of Sudan. A total of 87 date palm orchards (average 82 trees/orchard) in 29 locations in 7 localities in northern states were systematically surveyed during 2009-2010-2011 for the occurrence of fungal diseases. Results revealed that, trunk rot disease caused by Thielaviopsis. paradoxa occurred at high levels in Merowe (35%), Eldeba (65%), Eldamer (96%), Dongla (45%) localities and at low level in Abuhamed (2%), and East Nile (6%). Bud rot (Belaat) disease caused by P. palmivora was observed to occur in Merowe, Eldeba, Dongla and East Nile localities at an incidence of 18%, 31%, 33% and 17%, respectively. Diplodia rot associated with D. phoenicum was reported only in Merowe at a level of 19% and in East Nile at 23 % level. Ganoderma foot rot caused by G. zonatum was observed at Elbawga scheme (100%), Elselaim scheme (24%) and Tangasi Elsoque (37%) in Berber, East Nile and Merowe locality, respectively. An incidence level of 100% of the fusarium wilt disease caused by F. oxysporum was observed only at Tangasi Elrewase (Merowe locality). Further characterization of F. oxysporum using molecular markers is needed for proper identification. In conclusion, Date palm under Sudan conditions is affected by many fungal diseases causing considerable losses in yield. Thus a strategy for proper management of these diseases should be formulated.
