Precision Laboratories has released Persist Ultra to its lineup of methylated seed oils (MSO). Combining a unique blend of methylated canola oil and surfactants, Persist Ultra optimizes pesticide performance and mixing characteristics with a wider range of tank mix partners, according to the company.

Persist Ultra is a manufacturer-approved adjuvant that is proven to outperform ordinary methylated seed oils in enhancing the biological performance of Kixor herbicide technology across a wide range of weeds. With high levels of unsaturated C18 fatty acids, Persist Ultra offers the best performance in enhancing weed control on a broad range of species.

"Persist Ultra was developed to help growers protect their yield potential, and deliver consistent performance in stressful growing conditions and on tough weed species," said James Reiss, vice president of agriculture chemistries at Precision Laboratories. "We've seen, in both formal research studies and onfarm use, that Persist Ultra enhances the performance of the newest herbicide technologies, delivering consistent weed control for optimum yields."

In a 2009 research study using Kixor technology, BASF compared Persist Ultra to ordinary MSOs and tested them against four weed species — giant ragweed, kochia, ivyleaf morningglory and velvetleaf. Persist Ultra outperformed the ordinary MSOs with an average control rate of 90 percent.
