As the global population increases and the economy continues to shift growers are asked to produce more food yet, consumers are becoming more conscious than ever about the origins of what's on their plates. With the consumer-driven push toward cleaner food, growers depend on biorational products to offer powerful sustainable pest control. And, growers need an effective tool to meet the demands of today’s consumers who want their food produced with minimal impact to the environment including pollinators. This is where the unique set of benefits of KING’S BT.


KING’S BT is a naturally occurring soil bacteria, containing Bacillus thuringiensis subsp. Kurstaki, ideal for controlling Lepidoptera larvae (worms or caterpillars) in most of crops and forest.

Bacillus thuringiensis (Bt) is considered the most successful bio insecticide of the last century, unlike synthetic pesticides, it has a complex mode of action. Late in Bt life cycle, during spore formation, Bt cells produce insecticidal proteins known as delta-endotoxins, or Cry toxins because they form crystals inside the cells. Bt products contain spores, crystals, cell debris, and other components of the harvested fermentation biomass.

Upon ingestion by Lepidoptera larvae, Bt protein is activated by alkaline (pH>7)-dependent proteins that change the Bt protein into its active form within the insect's digestive tract. This activation enables the protein to bind to receptors located on the intestinal lining. Once the protein binds, it forms holes in the gut, leading to cell death, septicemia, and insect death. Normally, the larva stops feeding (often in less than an hour) and dies with several days.

Therefore, KING’S BT has no known cross-resistance with other chemical pesticides. It is highly specific towards Lepidoptera larvae, with no toxicity toward predatory mites or bees. That makes it an ideal solution and a good option for incorporation into Integrated Pest Management (IPM) programs and resistance management.


Moreover, KING’S BT has no preharvest interval (PHI), or maximum residue limits (MRL) for exported commodities. Coupled with minimal re-entry interval (4-hour REI), KING’S BT can be applied up to harvest, provides flexibility in crop and harvest management compared to pesticides requiring longer waiting periods before field re-entry and harvest.


Unlike chemical pesticides, KING’S BT is a naturally occurring bacterium and does not harm non-targeted organisms, including beneficial insects or pollinators, birds, or mammals. It is a safe and environmentally friendly alternative for pest control, making it suitable for organic farming and gardening.
