mlovecan Posted October 7, 2010 Report Share Posted October 7, 2010 (edited) Can anyone confirm or verify any attacks on crownshafted palms??? I thought I had seen everything in crazy palm ideas. talked a lot about this in Italian! but I not know if really ok ??? only talked , but none has shown?? tampa scott:The problem is very serious in southern europe The only two crownshafted palms I have seen reference to attacks are Areca Catechu and R. Regia - I've witnessed none but our island has few crownshafted palms ( other than in my garden - I have about 20 or so ). My theory to species attacked is this is dictated by: 1) specific tastes - CIDP seems to be a consistant favourite, followed by Edible Date Palms - in the case of our island. But the sequence seems to vary by area - kind of a specific taste by specific local strain ) 2) Ease of Entry to Palm - they seem to have no problem drilling right into the porous trunk of CIDP's / Edible Date Palms - they also seem to find an easy entry at the bottom of Phoenix species where adventitious roots break up the smooth trunk. IMO crownshafted palms are the least suspectible since there are few "breaks" in the contour and the trunks are usually fairly solid. The arrival of the Rino Beetle ( I first saw one of these two years ago ) seems to have accelerated the infection rate somewhat - they work in close co-operation with the RPW and are very effective hole drillers! Like Gyuseppe stated - this is a very serious problem in Southern Europe. We made some progress last year - our municipality spent money on treatment and prevention ( the number of flying RPW went down quite noticably ) but the money has since dried up - Greek economic crisis and all. The worst part is we have many, many mature CIDP stumps - large CIDP's that have been dead for 2 or 3 years and nobody cares to chop them down - they continue to host vast colonies of RPW. One such stump on our road to the city was surrounded by volunteer seedlings ( about 30 or 40 ). Now, the seedlings have also succumbed - small wonder. The owners of these dead trees just don't care - a palm tree is just a tree and it's no big deal to them - some even have the attitude that if they lost a valuable tree, everybody else should lose theirs too. Very, very tragic and depressing to watch - I almost threw in the towel when I lost my first tree and just resigned to the fact I was no longer able to grow palms any more. However, that said, Bayer Confidor is an excellent product - very near 100% success rate - and since discovering it, I have some hope - at least for my garden.
