Bacillus thuringiensis aizawai

XenTari® Biological Insecticide

XenTari® Biological Insecticide is the world’s only biological insecticide containing a natural, potent strain (ABTS-1857) of the microorganism Bacillus thuringiensis subspecies aizawai (Bta).  XenTari’s unique profile of insecticidal proteins provides exceptional control of difficult to control pests like armyworms and diamondback moth.

  • Acts fast; larvae stop feeding within minutes
  • Exempt from residue tolerance with as short as a 0-day PHI and 4-hr REI, allowing fruit to be harvested within hours of application (follow local labels and guidelines)
  • Effective resistance management, having never developed cross-resistance with any other insecticide
  • Tank mixable with most insecticides, fungicides, and foliar nutrients
OMRI caterpillar pest control

Consistent, reliable field performance

Every batch of XenTari is tested with a live insect bioassay, the most rigorous quality control in the industry, to make sure it meets the high-quality performance standards that growers expect.

Broad-spectrum caterpillar control

XenTari effectively controls almost all caterpillar pests with especially effective control of difficult to control Lepidoptera, like armyworms and diamondback moth.

Protect the environment and your workers

XenTari does not harm important beneficial insects, such as bees for pollination or insect predators used in the control of other insect pests. It also holds the shortest worker re-entry (REI) and pre-harvest intervals (PHIs) allowed by law.

Exempt from tolerances

Because it is exempt from residue tolerances, XenTari is the perfect choice for operations with multiple harvests and for late-season applications.
