Early August is often a time when tomato hornworms are at their worst. These destructive pests can decimate tomato plants as they munch through foliage, even defoliating them in extreme cases. Once you spot adult hornworms or their hungry larvae on your plants, act fast to save your tomato crop.
Tomato hornworms may be hard to spot. Their pale green bodies blend in with the leaves but are distinguishable thanks to their distinctive markings and horn. When growing tomatoes, if you see lots of holes or damage to leaves or fruits, the quickest tactic is to handpick the pests or use organic sprays, particularly Bacillus thuringiensis (available at Amazon).
