Diseases of date palms
Dates None Given
Please help me to know the reasons for the emergence of these symptoms. Is the reasons based on plant pathology? Note I am waiting in the outer shell of the branches of the fruits which may show some of the symptoms .
Finally, I would like to thank you for giving me the opportunity to communicate with you very much

This looks like inflorescence rot "El Khamj" mainly caused by two plant pathogenic fungi: Mauginiella scattae (whitish or pink rot) and/or Thielaviopsis paradoxa (brown to black rot). The disease can be managed by targeted spraying of fungicides to the base of leaves (spath emergence points) prior to the emergence of spaths. Hope this helps.

There is a disease called wilt of fruit bunch that I detected in Saudi Arabia caused by F. moniliforme and causes symptoms related to that in the photos above. We treated this disease in many farms using fungicides that should be sprayed early at the time of flowering.

Thanks for you answer. Yes, we too suspect it could be Fusarium moniliforme. We have tried to address this problem in another question. https://www.plantvillage.org/en/quest... almost 8 years ago.
