Bacillus Thuringiensis (Thuricide)


Bonide's Thuricide is a liquid formulation of bacteria, Bacillus Thuringiensis (Bt), which is specific to leaf eating caterpillars. Controls loopers, cabbageworms, tomato hornworms, leaf rollers, gypsy moths and many others. The insects stop feeding and die within 2-3 days of ingestion. There is no residue problem, and being exempt from tolerance requirements, this product may be applied at recommended amounts up to the day of harvest. Will not harm beneficial insects. One 8 oz. bottle treats over 5,000 sq. ft. Not registered for sale in California.

Directions for use:
Mix 1-4 tsp. per gallon of water and apply at first sign of infestation. Repeat at weekly intervals as needed to maintain control. May be applied by hose or pressurized sprayers. Apply thoroughly to upper and lower leaf surfaces, but not to the point of excessive run-off.
