Bacillus (BT)

Thuricide® Bacillus Thuringiensis (BT) is a naturally occurring, soil borne organism that has gained recent popularity for its ability to control certain insect pests in a natural, environmentally friendly manner.

Bacterial agents, like Thuricide, are effective in controlling insects in the larva (worm/caterpillar) stage. The larva stage in an insect's life cycle is the stage during which most of the feeding occurs. Stopping the insect in this stage will effectively stop it from reproducing.

Thuricide Bacillus Thuringiensis should be applied to the foliage of plants infested with larvae. If possible, apply to the underside of the leaf surface - for two reasons, most larva feed from the underside of the leaf surface and BT is broken down faster in sunlight, so applications to the undersides of the leaf surfaces will increase its effectiveness.

After the BT spores are ingested they start producing crystalline toxins. The crystalline toxins paralyze the digestive tract of the larva, causing it to stop eating. Death will follow, time of death can range from 12 hours to 5 days after ingestion of Thuricide Bacillus Thuringiensis.
