Kovar Exalt HSO®

High Surfactant Oil Concentrate

Kovar Exalt HSO® 

If you need an adjuvant that increases herbicide performance on your toughest weed species and even under tough dry environmental growing conditions then this high surfactant crop oil concentrate is up to meet the challenge. Kovar Exalt HSO is a 60/40 modified seed oil/surfactant that is used at lower use rates than conventional products and is especially beneficial when used with multiple herbicide tank mixes with different adjuvant requirements. The power of the oil component ensures actives can penetrate the leaf cuticle while the surfactant component enables more of the leaf surface to have direct contact allowing for more active to enter the plant providing increased product performance. Kovar Exalt HSO also meets the requirements for use of several of the newest traited crop technologies in the marketplace. You are also contributing to environmental stewardship by using a product made from a locally grown renewable oil source – soybean.
