Spear® LEP is Vestaron’s revolutionary bioinsecticide for vegetables and other high-value field crops. Targeting lepidopteran pests such as loopers, worms and caterpillars, field trials with Spear LEP show performance that is equivalent 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 IPM and resistance management tool.

A SOLUTION BY VESTARON
Vestaron is The Peptide Company dedicated to improving the safety, efficacy and sustainability of crop protection through migration from synthetic 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 the development of a wide variety of effective crop protection solutions. Vestaron brands are emPOWERed by Peptides – 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.
