Help identifying leaf symptons.

Any help would be appreciated. One is a squiggly line the other is like a white spiral. Thanks in advance

Re: Help identifying leaf symptons.

Squggly line are leaf miners. It is a larvae of a fly. They cause mostly cosmetic damage. Squish the bug at the end of the trail before it takes off.
The sprial white circle under the leaves are white flies. The adults will be flitting about. Lady bugs are predators.
Hose off the leaves with a jet of water. Adults will fly off so you will have to do this repeatedly.
Check the undersides of the leaves frequently
treat with insecticidal soap or horticultural oil spray. If you mix your own you can add up to 1/2 cup of alcohol to the mix
Straight up alcohol works too.
Remove and destroy all severely infested leaves.
Check other plants in the area white flies have multiple hosts.
Happy gardening in Hawaii. Gardens are where people grow.

Great information! Thanks! I just released a bunch of ladybugs into my garden. I'm hoping that will help. Also I just bought neem oil for the leaves. Thanks again

The purple ladybugs seem to like white flies more than the spotted ones but they both will eat them. Lacewings are also predators.
Whiteflies are cyclical depending on the population of their predators.

Thanks! My local hardware store actually sold the spotted kind. I picked up like 1500 bugs for 7 bucks. Lol.

Re: Help identifying leaf symptons.

Hii there :)
I'm not meaning to hi-jack your thread!

I Just wanted to be helpful, add to the great above suggestions, & ask maybe someone who knows exactly:

What would be the best time of day to use the water-based treatments: early morning or evening? Or!?

Is it true that getting water on the leaves of your plants during hot days or in bright sunshine is something to avoid? (I think I read that if you wet the leaves when it is bright or/and hot outside the leaves will burn?)

This extra question might be off topic, but I'm going to throw it in, sorry!

What about milk sprays or baking soda sprays for fungal/disease protection? Should those types of sprays be sprayed in sunny conditions in order to work? :)
