Weevil insecticide

Recommended Posts

A few of my palms have been attacked by weevils.   Its happened before and the palms have recovered but this time one of my Dypsis dark mealy bugs have suffered more damage than usual - luckily my second dark mealy bugs appears untouched. I want to get on top of those weevils before they cause too much more damage.  So what's the best chemical to control weevils?

Dipel® should do it, or any product with BT as the main.

Need a systemic. Anything with a neonicotinoid will work great and provide 3,4,6 or even 12 month protection depending on the fungicide.

Steve, are you referring to Sugar Cane Weevil?

If so, the current recommended treatment is Fipronil

You could also try anything that contains chlorpyrifos, but it is nasty stuff and you may not be able to get it anymore (it is effective though)

Traveled with David Tanswell and Phillip Arrowsmith for a few weeks around Colombia in June. I never knew how brutal that cane weevil was until talking to them. They were going over all the pest you guys have over their to contend with. Not easy.

Thanks fellas, I ended up getting a product called CONGUARD which contains a chemical called IMIDACLOPRID.  I'll give it a try and see what happens.

Daryl,

Interesting you mentioned FIPRONIL. I've used it around my house for termites and ants and it's deadly stuff.  I have not seen an ant or termite in the 4 years since I last used it.  Although in saying that, I thought it only worked on social insects (ants, bees and termites etc}   But if it works on weevils that's even better because I have a fresh unopened bottle of TERMIDOR sitting in the garage.

I guess every palm area has their own set of pests and problems Len! Cane Weevil is a bitch though...I lost quite a few mature palms at my old place...seems like they especially like Pritchardia!  They are not always a death sentence and some palms recover ok, just with holes through them...I reckon drought kills more palms than insects though!

Yep, no where is easy to grow palms. Different challenges. Well, it’s easy to grow in Hawaii... :)

If you mix a systemic consisting of 20% imidacloprid  with equal amount of tetrahydrofurfuryl alcohol (an alcohol gained from sugar canes) the resulting compound is a systemic that travels super fast inside the palm. Thus one can also apply it through injections in to the root zone. I do not know, whether future versions of imidacloprid have improved properties, but original substance could travel only upwards from the part of the plant on which it has been applied.
