These three crops are members of the Solanaceae family, and can be either direct-seeded or planted as transplants. Although these crops are closely related, some herbicides are registered for use in one crop but not the others. For example, “Tomatoes only, must be established” means that particular herbicide is registered only for use on tomatoes, and only if the plants are beyond the 5- to 6-leaf stage. Always consult the label for rate and timing specifics.
