The application of synthetic insecticides (Pesticides) on palm trees is a widespread technique in species such as Phoenix canariensis, where most of the Red Palm Weevil attacks are concentrated on the crown. This technique loses effectiveness when lateral and basal attacks occur, since the insecticide does not reach where the larvae are eating..
The risk of using these toxic actives is high, since due to the effect of drift by the wind or the blasting that occurs when spraying, they can cause health problems to the manpower, passers-by or inhabitants of houses and domestic animals. Added to this, is the increasing prohibition by the authorities of a large number of insecticides that were in common use.
Organic insecticides are very effective, but must be used in compliance with all the manufacturer’s recommendations. This is the case of Meral and the Piretro Natura that in a homogeneous mixture are capable of controlling the plague of the red palm weevil in all its stages (The eggs sprayed with the solution do not hatch, larvae, pupae and adults die on contact with the product).
You can access the trials of the product of natural origin and with an ecological certificate that was presented at the Polytechnic University of Valencia (UPV).
