Abstract:

It is known that the fungus Fusarium involved in the cases of date palm inflorescence rot, the results of survey and investigation in the general  areas of cultivation of palm groves in Iraq for the period from 2005 to 2011, isolating and diagnosis pathogens from soil and plant parts, testing pathogenicity on small plants, many laboratory and field studies, showing that the main causes of some important and serious pathological phenomena that spread largely on the palm and caused death were species of the fungus Fusarium. The results proved that the cases of yellowing and dries fronds and numbness dates caused by some aggressive races and toxic metabolites (toxins) of the fungus Fusarium solani, which resides in the root zone and contributes to the weakness of palm, and make it susceptible to other vulnerable fungi like Thiealophiopsis paradoxa which cause curvature of the summit as a results of cellulose analysis. While Fusarium proliferatum and the toxins produced by this fungus causing the rapid death and dries completely of the palm(the phenomenon of embalming palm by death of standing palm and drought summit completely).The fungus moves through xylem vessels in the trunk and kill them, and prevent the transmission of water, nutrients and leading to decimation palm during a short period, often the fungus was more active at low temperatures during winter.
