Try this: Add one tablespoon of regular liquid dishwashing soap to a cup of vegetable oil and shake well. Mix two tablespoons of this solution into a cup of water shake well and spray on those infested undersides.

I got this from another forum. They say it works on white flies. Maybe it will work on aphids.

Try just hosing down the undersides of the plants first. Aphids are pretty easily killed. That worked better on my branywines than a straight up dishsoap & water concoction. You may have to do it a few times if they come back. Hopefully the ladybugs will find your plant & help you out :) You could also purchase some ladybugs too. Can't have too many of those!

Since it is only one plant....

Take leaf with aphids between thumb and fore finger.
Slide leaf through fingers, removing and/or squishing all
aphids in the process.
Repeat for all infected leaves and every couple of days as
necessary.

Doesn't get any more "organic" than that. Plus you have the
added benefit of not impacting potential predators (ie. lady bugs/lacewings) of the aphids, which any spray method, organic or not, will do.

ladybugs!
I thought I would give it a try when my garden had an infestation. It was so bad that they destroyed ALL the baby radish leaves and the tomatoes were covered as well. Thoses little buggers picked them clean and I hav'nt seen one since.

Yea...if only we could go out to the local grocery or Wal-Mart & pick up some ladybugs. The finding part isn't too easy at all, at least for some.

I've got aphids on mine as well and watering them off hasn't been much help and squashing them between the fingers is only temporary. I've read that it releases a chemical letting other aphids know to drop off the leaves but it doesn't seem to work out that way in my garden. Look up Garlic Oil Spray. I have not used it yet but I'm going to try it when the mix is done setting.

I don't like to use any chemicals if I don't have to. So, for me, I take care of those critters with a CHAINSAW and a SHOTGUN!!!!!!!!! :>)

I looked up the aphid question on the FAQ's and it mentions some concoction with cayenne pepper. I'm just afraid of spraying something on the plant that's going to be damaging to it. Seems like pepper would damage the plant somehow?

Perhaps garlic oil spray is the way to go?

Ugh...I can't stand these things. How annoying. And they give me the chills!

My organic gardening solution is to not grow Aunt Gerties Gold in the future. It is suprising how well this approach works. I simply have stopped growing those things that do not grow well or get attacked by bugs like potatoes. Just too many colorado potato beetles to grow them and I refuse to use poisons also. although there is a BT for colorado potato beetles today.

Recently I give up on those squash that get killed by the SVB.

they make a product called super fine oil. It is paraffin wax. you spray it on and after the water drys off the bug is coated in wax and dies. it supposedly kills mites and I am pretty sure aphids. but of course they keep coming back. I think it kills eggs also.

snoop92,
I had an aphid and spider mite problem a few days ago. Jeanne made me use dish soap instead of poison and it worked in just over a day. Good bugs are back but I used to much soap and plants look a bit sick. I got some real good guidance from folks when I posted the following:

Here is a link that might be useful: RED aphids and spider mites

I bought ladybugs at a local nursery and the girls and I had great fun distributing them. This is Emily, organizing the 'troops' Luckily she isn't too bug phobic.

I also had a problem w/ aphids this year on 4 of my tomato plants, and I launced an assault against them with 2 praying mantix egg sacks and a bunch of green laced wings. I read that they hang around your garden better than the lady bugs that tend to fly away, and both of them are aphid eating machines, and are readily available online. I ordered mine from:

no more aphids!!

Yea, if you do release ladybugs, do it at dusk. They'll hang around, eat all night, lay some eggs, fly away in the morning and by the time your Aphids are back, the eggs will have hatched. :) Maybe I need to stop by a local nursery to get some b4 all my hot pepper plants are dead.

My grandma soaked chewing tobacco in water, strained it and mixed it with soap and sprayed it on. Very organic and totally poisonous. It worked but,thank goodness, aphids have never been a problem for me - so far the native predators have always kicked in and killed them off.
White flies rise up when you shake the branch. For those you need yellow sticky strips. Aphids shed their white skins - if that's what it is, it's the green bugs you have to get rid of and a soapy water drench generally does it.

tobacco leaf virus? hmmm

Oldroser. Yes was telling someone about the chewing tobacco brew the other day but couldn't remember what they used it for but knew it was insects and think they claimed it helped against some diseases also as I recall. Was just a kid then. A lot of the brews of the old timers worked. JD

Well, for two years, I lived just north of you in Moses Lake, WA. Maybe the Chinook wind brought something up our way that infested my brain cells. :>)

Definitely ladybugs. I had an entire cherry tree caked with aphids last year. I released a package of ladybugs and within a couple weeks there were NO aphids. I still see ladybugs in my garden.

It was fun watching the hungry instars gobbling up aphids.

So, if I were to get ladybugs, would they just eat up the aphids and not to damage to the tomato plants?

I want to make sure that these guys will only help me and not hurt anything!

These aphids are out of control.

I am growing cherry tomatoes indoors in my sunroom and have an aphid infestation which I am trying to cure. My questions is whether I can eat the tomatoes with the sticky residue or not. I can wash them in soapy water to remove the residue but is that enough?

Ladybugs are OK but green lacewing larva are best by far.I've trialed both and am 100% sold on lacewings. Although Lee's squish technique is quicker and cheaper...:)

To answer the above two questions, no ladybugs or lacewings won't damage the plant.

And if any part of the tomato looks weird just slice that part off. Otherwise, after you remove the honeydew thoroughly from the tomato, if it looks OK, should be fine to eat.
