Vigor is a premium paraffin-based crop oil concentrate designed for use with herbicides that require a paraffinic COC adjuvant. It features an 83/17 blend of highly unsulfonated paraffinic oil and a high-quality surfactant system that combines strong penetration with excellent wetting and coverage. Vigor helps increase herbicide activity by improving spray coverage, penetration, and dwell time on leaf surfaces, and it mixes easily with UAN and AMS even in cold water. Because Vigor can enhance herbicide performance, use caution when crops are under drought stress or during periods of high heat and humidity.
