Notes:

CoStar is a biological insecticide specific for use against the lepidopterous larvae listed on the label. CoStar must be eaten by the larvae to be effective. Since CoStar is most effective against small, newly hatched larvae, an early scouting program to determine early infestations is recommended. After consuming a lethal dose of CoStar, larvae stop eating within an hour, but may remain on the foliage until they die, usually within several days. Affected larvae move more slowly and tend to become shriveled and discolored before dying.

For complete use directions, please refer to the product label.
