Palm Weevil..copper tubes

[casablanca]

PF - Thanks for that, would hate to lose mine.

Hi 2 feet up from the base of the palm and then around the palm every 6 inches.

AJJ could you tell me if there is a particular position/height at which to insert the tube? Also is it just one insertion, at the same point, every six months??

So that's a "sorry I can't" then??

We've started treating all our trees (about 200) by injecting the liquid directly into the trunk via a plastic tube. According to Ramblizo this needs to be done twice a year whereas before we were dosing them with 10litres of mixture every 6 weeks. So far all seem fine but once a tree is infested there seems little can be done to save them.

I always thought that if you had an infestation you neeed to get "to the core" using the spiked tubes to enable a more direct treatment. As a prevention it is only necessary to spray the diluted mixture onto the palm, targeting where the fronds join the main tree. Could be wrong though??

[NormanM]

Do these chemicals prevent infestation, or just kill an existing one?

[AJJ]

The way to kill a tree stump used to be to bang in some copper nails so I shouldn't use copper pipe. Copper sulphate gets rid of algae in green swimming pools like magic!

Yes I know but what I am asking is...copper applicator instead of the green plastic one....is it ok to use as a little worried cause trees reckon not to like copper

I got the chemicals from them, told them what I had, after two applications they were found dead around the palm tree, I have applied again  and so far no munching sound and no more dead beetles. I suppose around a dozen beetles were dead around the palm. I will keep applying the chemicals till xmas  on a 6 week cycle and hopefully it will be the end of them. Best of luck with what you are doing.

I think I saw a palm weevil round my tree so went to Mora Oil gun shop for plastic sos palm tube to insert into tree.They hadn't any and he showed me a copper one.Bit wary to use this..anyone tried it?
