Mediterranean is losing battle – Palmkiller ( rynchophorus ferrugineus )
His favorite food in our area are canary dates ( phoenix canariensis ) but when they eat them all on some area they attack and other palm trees. They are able in a few months to destroy the centuries-old specimens. In Italy, souther of Rome, almost all palms are devastated, people are fighting with this bug in France, Spain, Greece and Portugal.
Ways to combat this pest has a price because you need several times a year to spray tplant with certain fluids. The best thing proved to be is harmless biorend with almost 99% effectiveness in the prevention and treatment, and then very toxic insecticide based on imidaklopirid like Confidor, Boxer, Dali … Both fluids should be sprayed once a month from March to December to be sure, with biroend you must spray the heart of the palm trees, with insecticide in the heart and root of palm, proof of reliability both agents arrive daily from people in the regions in which is an insect attack. More about the application and quantities for spraying you can find here on Croatia palm society page. And more about bug you can hear here on Croatian language.
It is hard to imagine that something that has been growing for centuries disappear in few months. Insect arrived some years ago on Adriatic coast and has already devastated about 100 kilometers of coastline planted palms. Expanding unstoppable because only some people want to spray their plants, because of ignorance and lack of care, or because of finances, and it is predicted that for 5-10 years canary date palms will no longer exist at the Adriatic coast, so we will be able to see these scenes only in pictures. 🙁
