big fat thing ate my tomato leaves?

Post by lanzpeter » Fri, 31 Jul 1998 04:00:00



I had this tomato plan in a big terra cotta pot.  Potting soil, which I
have never had good luck using with tomatos.  It seems I can't keep it
moist enough.  In any case, a less than robust plant.  Yesterday, I
looked at it as I passed, and noticed that half the leaves were
missing,except for the stem and the main vain running up the middle. I
looked closer and found a horror movie of a thing.  It was about the
diameter of my ring finger, and 3/4 the length.  Green the color of the
tomato plant stem.  It looks like it has no features.  No eyes, no
mouth.  Is this the famous tomato horn worm?  I think I can control them
by removing them, but if they can eat half of a plant in one morning...
What to do?

thanks

lp

If it has a *** looking, but ineffective on people, horn on one end and a
muncher on the other end it is the THW.  I have had a bumper crop of them
this year.  I pick off 6 or 7 a day from my 20 plants.  Anyone have a more
efficient control method?

It does sound like you have the famous tomato hornworm. You found a
smallish one; the full-sized ones can be close to six inches long. For
container plants, the best control is picking them off by hand and
stomping on them. This can be very satisfying, especially after you've
seen the damage they do to your tomato plants. I've also heard that koi
like to eat them, if you happen to have a fish pound.
Although they're large and voracious, usually the hornworms don't invade
in great numbers. Look closely for more of them (as you've noticed,
they're well-camouflaged) and you can probably eliminate them by hand.

I've read that BTK will stop the little ones (Has any one ever seen a small
Hornworm?).

I have not tried this myself. I had pick the beasts and compost 'em.

Dipel and Thuricide work beautifully.  The active ingredient in both is a
bacterium called B. thurengenis var. Kurtaki (BtK), which kills off
hornworms, fruitworms, cabbage worms, and other various wormy horrors.  It
even keeps squash vine borers in check, which I discovered much to my joy
and happiness after our zucchini came down with them.  I went to the local
feed 'n' seed, picked up a bottle of Thuricide and a syringe, and injected
both of our plants with lots of Thuricide solution.  We lost a bunch of
older leaves and two fruits that got "bored" out, but I'm happy to report
that last night my sweetie and I harvested the first healthy fruit from
the more-or-less recovered plants.  Two sprayings of Thuricide pretty much
took care of a fruit- and hornworm problem on the tomatoes too.

Picking them off is one way.
Seven dust is another.

Keep on pluckin!
I for one feel that tomato horn worms grow out of the seed with the plant.
Government ***? Or alien invasion?

I think they are cleverly disguised Amway salespeople ... when cut, they
bleed that "Simple Green" solution.
They're just waiting around for us to let our guard down so they can sell
us distributorships.

i pull `em off and toss `em to the mockingbirds.

i found the shriveled carcass of a hornworm the other day covered with
eggs from those parasitic wasps.they apparently just sucked him dry and
flew away.
