In the last two decades, pests have appeared that have no predator. The use of chemical insecticides to combat them affected other pollinating species, such as bees or birds. Marimurtra has been managing FitoZero in the garden for 6 years (no chemical treatment).
When treatments were carried out with chemical products, four treatments were carried out; and with the management with ecological products, the number of treatments must be doubled in order to have a similar effectiveness. Occasionally, there are different circumstances that make it difficult to carry out all the treatments, and when constancy cannot be maintained is when there are these casualties of different specimens. It is for this reason that these two specimens of Phoenix canariensis have been cut down, specifically due to the attack of the weevil beetle, also known as the red palm weevil (Rhynchophorus ferrugineus).
However, there are different causes that can lead to the loss of different specimens, such as pests, climate change or the appearance of invasive species, among others.
Before or after the palm tree is removed, the species planted is being replaced. In order to increase diversity and reduce the number of specimens of the same species and to avoid having to combat these new pests that have no predator.
