"Vestaron is The Peptide Company dedicated to improving the safety, efficacy and sustainability of crop protection through migration from chemical pesticides to biological peptides

Initially, Vestaron is focused on a class of peptides that kills insect pests efficiently, but is safe for humans, birds, fish, pollinators and the environment. As part of this, the company has developed a proprietary platform for peptide optimization and fermentation-based peptide production that will allow development of a wide variety of biologic crop protection solutions.

Vestaron is proud to bring you the Power of Peptides through the SPEAR® brand family – providing new technology with a unique mode of action in a biological solution equal to, and often better, than the synthetic options; creating the opportunity to incorporate a new IRAC Group 32 into rotation recommendations for resistance management."

Leprotec® is a versatile, liquid formulation of the lepidopteran active Bt kurstaki strain EVB-113-19. It 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. Leprotec is OMRI listed, giving growers the flexibility to use on conventional as well as organic acreage. Leprotec is also the ideal partner for use with Vestaron’s Spear®-Lep bioinsecticide. Btk disrupts the insect mid-gut and opens passage for the Spear peptide to reach target receptors in the nervous system. This leads to increased efficacy of Spear against the target insect.

Leprotec

Spear

Spear®-Lep is Vestaron’s revolutionary bioinsecticide for fruits, vegetables and other high-value field and orchard crops. Targeting lepidopteran pests such as loopers, worms and caterpillars, field trials with Spear- Lep show performance that is equal or superior to conventional insecticides. With no known resistance or cross-resistance, Spear-Lep works as a standalone, or in rotation with conventional insecticides as an excellent resistance management tool for IPM.

Spear® Lep

Leprotec®

Spear®-T controls four of the major greenhouse and nursery pests - aphids, spider mites, thrips and whiteflies - as efficiently as conventional insecticides, and with the safety and sustainability of biologicals. With an excellent safety profile for pollinators and other beneficials, Spear-T also has a short 4-hour restrictedentry interval (REI) and 0-day pre-harvest interval (PHI). The combination of these characteristics makes Spear-T a valuable new tool for greenhouse and nursery pest management, as well as a safe and versatile rotation partner in integrated pest management programs.
