Damage to petunias by tobacco budworm has reduced the popularity of this colorful summer annual in some parts of California. However, properly timed applications of Bacillus thuringiensis (Bt) can effectively manage budworm in home gardens and in greenhouses. Lacewing applications proved ineffective on petunias, but may control tobacco budworm on other plants.
