Spear® LEP is Vestaron’s revolutionary insecticide for tree nuts, 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 equivalent to conventional insecticides. With no known resistance or cross resistance, Spear LEP works as a standalone or in rotation with conventional insecticides. Spear LEP is an excellent IPM and resistance management tool.
Tank mixing Bt + Spear LEP extends the residual action, resulting in good pest control, better crop protection, time and fuel savings, less wear and tear on equipment, and less environmental impact — this results in lower production costs and higher return on investment for us, and we definitely envision continued evaluation of Spear LEP as part of our regular spray program moving forward!

btk biological insecticide
Leprotec® is Vestaron’s Btk bioinsecticide that is the ideal partner for use with Spear LEP. When ingested together, the Btk proteins perforate the insect mid-gut allowing the Spearpeptide to access the target receptor in the nervous system, killing the pest.
