Adeje Adopts Advanced Plant Endotherapy to Combat Urban Pests

Maintaining urban greenery in high-traffic tourist destinations requires a delicate balance between ecological health and public safety. To address this, the Adeje Town Hall and the Municipal Services Company of Adeje (EMSA) have launched a specialized plant endotherapy program designed to curb the spread of whitefly and other pests affecting the municipality’s palm groves and urban forests.

This initiative marks a shift away from traditional pest control methods, prioritizing a more precise, systemic approach to protect the local landscape while minimizing the environmental footprint in a region known for its constant tourist flow.

Understanding Plant Endotherapy: The “IV” for Trees

Unlike conventional phytosanitary treatments that rely on foliar spraying—where chemicals are applied to the surface of leaves—plant endotherapy is an advanced technique that involves the direct injection of active substances into the tree’s vascular system.

Once injected, the product is absorbed by the xylem, the plant’s internal transport tissue. From there, it is carried systemically to every part of the plant, including the roots, branches, leaves, and apexes. This method does more than just fight pests; it also allows technicians to administer essential nutrients to trees showing deficiencies or those requiring bio-stimulation to improve their overall resilience.

The Scope of Adeje’s Green Initiative

The program began during the Holy Week break in educational centers to minimize disruption. Following the prioritization of school zones, the treatment has expanded to other municipal locations, with the first phase expected to conclude during the first half of May.

The project represents a strategic investment of nearly 109,000 euros. This decision follows a successful experimental phase where 200 specimens were treated with positive results. According to Epifanio Díaz Hernández, the CEO of EMSA and Councilor for Works, Municipal Services, and Solid Government, the current project targets approximately 920 trees across 20 different municipal locations. Of these, 422 are palm trees and 498 are other species.

Díaz Hernández noted that endotherapy is particularly valuable in areas where conventional methods are impractical due to difficult access to the trees or because the plants are located in high-traffic pedestrian zones.

Why Endotherapy Outperforms Traditional Spraying

From a public health and environmental perspective, endotherapy offers several critical advantages over traditional spraying:

• Elimination of Chemical Drift: Because the treatment is injected directly into the plant, there is no airborne dispersion of chemicals. This removes the risk of accidental exposure to pedestrians, pets, and the professionals applying the treatment.
• Environmental Precision: The targeted nature of the injection ensures a homogeneous treatment of the affected tree without impacting surrounding flora or fauna.
• Long-Term Efficacy: Endotherapy provides a prolonged effect, meaning fewer applications are needed compared to surface sprays, which can be washed away by rain or degraded by sunlight.
• Tourism Compatibility: In a tourist-heavy environment like Adeje, avoiding the use of large spraying machinery and the associated chemical odors is essential for maintaining the aesthetic and sensory quality of the landscape.

Expected Outcomes and Future Outlook

While some results are expected to be visible in the short term, the full impact of the treatment will peak gradually over the coming months. Due to the warmth of the local climate in Adeje, officials anticipate that reinforcement treatments may be necessary in the near future to ensure the long-term health of the urban canopy.

By investing in systemic plant health, Adeje is not only protecting its visual appeal—specifically by reducing the scarring and damage caused by whitefly on palm trees—but is also establishing a safer, more cost-efficient model for urban forestry management.
