Bacillus thuringiensis is the main organic control for hornworms [Manduca sexta and M. quinquemaculata] on tomato plants. It's effective. But it's important to make sure that it indeed controls the greatest numbers of hornworms.
Specifically, hornworms are feisty defoliators. They know when they're most vulnerable, during the day and on leaf tops. So it's important to check the plant for the defoliating caterpillars quite late in the day. During daylight hours, they often chew in less visible places. Towards darkness, they're more likely to be found where they can be seen more easily, such as on leaf tips.

What is the best way to eliminate tomato hornworms in an organic fashion?
The best way to eliminate tomato hornworms is to use natural predators. Lady beetles, green lacewings and braconid wasps, as well the common wasp (Polistes spp.) are natural predators of the tomato. Lady beetles and green lacewings eat the larvae of the tomato hornworm, while braconid wasps lay their eggs on mature hornworms, which eat the caterpillar as it develops. Common wasps kill and feed off hornworms. If there aren't too many, they can be picked off by hand. They can be dropped in water mixed with liquid dish detergent to kill them. Another option is to use Bt (Bacillus thuringiensis), a natural bacterial disease that is deadly to tomato hornworms. It is sold in some pesticides, but they can also be used on their own. Bt produces proteins that paralyze the digestive system, causing starvation within several days. The disadvantage is that it is denigrated by the sun and foliar applications generally only last seven days or so. Though it won't work for current infestations, tilling the ground will help prevent an infestation the following year. Tomato pupae often inhabit the soil under tomato plants and winter over, emerging the following spring. The best results are gained when the soil is tilled soon after the tomatoes are harvested.
