March 17, 2020 – (Durham, North Carolina) – Vestaron Corporation announces that its Leprotec® Btk bioinsecticide (Bacillus thuringiensis ssp. kurstaki) is now registered in all 50 states, with its recent California state registration.

Leprotec is a versatile liquid formulation of the lepidopteran-active Bt kurstaki strain EVB-113-19.  This bioinsecticide may be used in a wide range of crops including outdoor food, non-food and greenhouse crops for control of loopers, worms and other caterpillars.

According to Vestaron’s field development biologist, Daniel Peck, PhD: “Leprotec is OMRI Listed, giving growers the flexibility to use on conventional as well as organic acreage.”

Leprotec is the ideal partner for use with Vestaron’s Spear® LEP bioinsecticide. After ingestion, Btk disrupts the insect mid-gut to open passage for the peptide contained in Spear LEP to effectively target receptors in the nervous system. This leads to insect death and extended residual activity.  Together, these two modes of action give growers a new tool for the management of insecticide resistance in some of the toughest to control pests such as Diamondback Moth and Navel Orangeworm.
