Larva Control

A plant-derived insecticide targeting over 300 species of caterpillars and larvae — delivering contact and ingestion kill with zero-hour re-entry interval and no toxicity restrictions for people or livestock.

Vegalab Larva Control
Eligible for organic production programs

Larva Control harnesses oxymatrine — a naturally occurring alkaloid extracted from the root of the Sophora plant — to disrupt an insect's development and physiology on contact and ingestion. It functions simultaneously as an insecticide, repellent, and anti-feedant, controlling over 300 larval species while leaving no harmful residue in soil or water. The 0-hour re-entry interval makes it compatible with intensive cropping schedules and IPM programs alike.

Key benefits
  • Controls over 300 larval and caterpillar species via contact and ingestion activity.
  • Disrupts insect development, physiology, and feeding — acts as insecticide, repellent, and anti-feedant.
  • 0-hour REI — no re-entry interval or toxicity restrictions for people or livestock.
  • Will not pollute water or soil; leaves no harmful residues on produce.
  • Nano-encapsulated active for improved stability and foliar coverage.
  • Compatible with IPM programs and organic production protocols.
