White spiral under canna leaves

tropicsnutAugust 15, 2009

I'm noticing white spiral trails under the leaves of my cannas. Can anyone tell me what disease is it and how to prevent it?

A photo would be helpful. I assume you are asking about "trails" on the underside of the leaf. I can only guess that what you have may be the slime trail of slugs! If so, you may try to use a bait to eliminate the slug which is nocturnal.

Sorry, but you have me. I do not believe this is a disease. WhatÂs the chance of this being eggs deposited by a moth or another insect?
How many leaves or plants are affected?

I noticed it first on a plant. I cut the leaves but it showed up on others a day later. There have been a lot of butterflies flying around. I'll observe a bit more. Thanks anyway.

I would suggest you take some of your leaves into the County Extension Office. They can offer suggestions and should be able to send it off to be examined if necessary. I would also like to have an answer also..
