DRONES have been called in to save Europe’s largest palm grove from pests.
Using drone technology to administer vaccines, experts are hoping to save the UNESCO World Heritage Site in Elche from a ravaging infestation of beetles.
Over the past few months, scores of red palm weevil have been burrowing up to a metre into the trunks of the site’s 200,000 palms.
If the trees are bored too often, the trees will become weak and eventually die.
But experts in Spain have come up with an ingenious idea to to inject the palm trees with a special fungus via drone.
