I have just planted one tomato plant and am concerned about tomato worms. What is the best product to protect my plant?

Hi Steve –

The best product for tomato hornworms is Bacillus thuringiensis, var. kurstaki, or Bt-k for short. Bt-k is most effective when applied to caterpillars during their 1st and 2nd instars, when they are still small. It must be ingested by the insect, as it is a stomach toxin. Harmless to humans, animals and beneficial insects. Here’s a couple of links that should help.

Good luck!
