THURICIDE HPC is a biological insecticide and is intended for use against caterpillars or worms. Apply at first sign of infestation when worms are small and repeat at 7 to 10-day intervals when needed to maintain control. THURICIDE HPC attacks the larval gut when eaten by the insect so thorough underleaf coverage is essential. After eating THURICIDE HPC, worms stop feeding and die within 12-72 hours. On agricultural crops, THURICIDE HPC may be applied up to the day of harvest. It contains three different strains of Bacillus thuringiensis. It can be used as a spray, or even as root rinse in hydroponics. Best to mix 1-4 teaspoons per gallon of water.
