Date palm diseases and insects.
Bayoud disease (مرض البيوض), the most dangerous disease; caused by Fusarium oxysporum f.sp. albedinis, occur in Morocco, Algeria and Mauritania, this disease caused disasters in Morocco and Algeria, leaving them only resistant palm varieties. and loss of genetic material (the gene pool) for date palms (extinction of many cultivars) in Morocco.
Fusarium wilt Disease, F. solani in Pakistan and F. oxysporum (not bayoud disease strain) and F. verticillioides in Saudi Arabia and others.
Inflorescence rot disease, (Khayas attala’a ‘خياس الطلع’ and Khamej ‘الخامج’), of the most dangerous diseases; several causes, caused by Mauginiella scaettae, and caused by Fusarium proliferatum, and caused by Ceratocystis paradoxa, is a widespread disease in virtually all date palm growing areas, infects the inflorescences of different varieties causing significant losses. especially in heavy rains before emergence of the spathes.

Belaat Disease (مرض بلعت), caused by Phytophthora palmivora, occur in Iraq, Morocco, Algeria and Emarat; decline and disappearance of the top of the date palm
Fruit rot disease, several fungi causes, it spreads in areas where there is moisture or rain during the ripening period of dates, especially in some varieties or late-ripening varieties.
Graphiola leaf spot, caused by Graphiola phoenicis, occur in several countries.
Omphalia root rot, occur in USA (California) and Mauritania.
red palm weevil, widespread in several countries, it’s the most dangerous insect pest that attack date palms.
date palm scale. Parlatoria blanchardi, widespread in several countries.

Lol, after writing this diligently, I found that the FAO actually wrote about this, here is a link to the rest of the diseases and more detailed, CHAPTER XII: DISEASES AND PESTS OF DATE PALM, and read the rest of the book if you want, Date Palm Cultivation.
