Abstract
Isolation and Identification of Fungi Caused Data Palms Inflorescence Rot Disease in Some Area of Diyala- Iraq and Control of Disease by Sodium Chloride Salt
Highlights
This work was carried out in Diyala Province, North of Baghdad, Iraq during 2016-2017 to isolation and identification the fungi caused Inflorescence rot on data palm and try to combat the disease by using sodium chloride salt. 32 infected samples were collected from 8 varieties of data palm which has been isolated 60 isolates of fungi belong to 6 genus and species of fungi which were Mauginiella scattae, Fusarum proliferum, Penicillum chrysogenum, Rhizopus spp., Mucor spp. and Aspergillus niger, the number of isolates for each one were [20,12,10,6,6,6] respectively
In Diyala – Iraq there were few and old studies That looked at this disease and its pathogenical causes there for the current study aimed to isolation and identification of fungi which caused inflorescence rot disease on data palms Phoenix dactylifera L. and using Sodium Chloride salt to fight disease on the trees
Six genus and species of fungi were isolated and identification from Infected spathes of data palm Phoenix dactylifera L. which collected from fields of Al-Migdadiyah in Diyala, Iraq, These fungi include Mauginiella scattae, Fusarium proliferum, Penicillum chrysogenum, Rhizopus spp., Mucor spp. and Aspergillus niger
Summary
In Iraq the main problems of data palm (Phoenix dactylifera L.) are exposed to many diseases and pests that effect on fruit production but nature and severity The problems vary by cultivar, location, weather, and cultural practices, These diseases caused by different type of pathogens like fungi , insect , nematode. (Zaid et al 2002; Al-Jboory 2007).Inflorescence rot is one of these disease which transmission during the infection season occurs through the contamination of male inflorescences during the pollination period and the first symptoms occur at the external surface of unopened spathes especially if emerges early in the spring season with typical brownish or rusty color lesion, Infected inflorescences remaining on palms from the previous season or infected leaf bases may serve to spread the disease (Abdullah et al 2005).The first recorded of it in Iraq in 1949 by Hanford this disease caused by Mauginiella scattae fungus (Al-Ani et al 1971). This work was carried out in Diyala Province, North of Baghdad, Iraq during 2016-2017 to isolation and identification the fungi caused Inflorescence rot on data palm and try to combat the disease by using sodium chloride salt.
