Monterey B.T. Biological Insecticide Ready-to-Use 32oz Monterey B.t. must be eaten by worms or caterpillars to be effective. After ingesting the insecticide, they immediately stop feeding, though they may otherwise appear to be unaffected for several days. Best results are obtained by treatments when worms are small; they must be actively feeding on treated, exposed foliage. You may apply Monterey B.t. up to and on the day of harvest. Apply Monterey B.t. when worms or caterpillars are first noticed, then repeat at 5 to 7 day intervals while they are active. Apply more frequently to control heavy infestations. Apply thoroughly to top and bottom of foliage. Reapply after heavy rains. Active Ingredients: Bacillus thuringiensis
