The Cabildo of Lanzarote has issued this Tuesday the results of the 'Diagnosis report and action plan for control of the Diocalandra frumenti plague in the palm trees of the municipalities of San Bartolomé, Tías and Yaiza', whose main objective has been to know the phytosanitary status of palm trees located in natural and rural agricultural and domestic and urban environments.
As they explain, said study, carried out by the company Gestión del Medio Rural de Canarias (GMR Canarias), diagnosed that "334 palm trees located in the three municipalities inspected suffer from this disease." Given that the total sample of trees analyzed was 417, "80% of these are affected by the pest."
In San Bartolomé, 69 of the 89 palms inspected had Diocalandra, that is, 77.5%. In Tías, more than 80% of the 140 palm trees surveyed show the presence of the pest. It remains, like San Bartolomé, one of the most affected areas of the Island. Finally, in the municipality of Yaiza, more than 75% of the 125 palms surveyed have symptoms of the presence of Diocalandra frumenti.
Among the measures proposed by the study is to "guarantee irrigation and the supply of fertilizers to the palm trees located in this area, the administration of phytosanitary treatments, the elimination of artificial corridors of cultivated palm trees on the margins of the roads that link areas affected with pest-free areas, and establish procedures for the management and elimination of infected plant remains ”.
The report also analyzed whether the inspected palms showed symptoms compatible with the presence of the disease Fusarium oxysporum, determining that 85% of the 417 palms reviewed had signs of this condition. Although this study is only based on the observation of symptoms, GMR Canarias will consider this information for the future of these trees.
