Harrell’s partners with 3BarBio to launch root health product Azo Root

Harrell’s, in collaboration with 3BarBio, recently launched Azo Root, a product set to transform plant health and root development across a range of agricultural and horticultural applications. Designed with Live-Microbe packaging, Azo Root ensures the delivery of live, high-concentration Azospirillum brasilense microbes directly to plant roots, promoting better growth, faster recovery and greater stress resistance, according to Harrell’s.

Azo Root’s formula addresses traditional challenges in microbial product efficacy by maintaining the viability of its beneficial bacteria from production through to application. According to the company, this resolves longstanding issues such as poor survival rates in transit, ensuring that users receive a potent and effective product.

Initial trials conducted by Harrell’s, including testing at Virginia Tech, have demonstrated significant improvements in turfgrass root health under stress conditions. These include increased root length, volume and overall biomass, showcasing Azo Root’s ability to enhance plant resilience and nutritional efficiency effectively.

“With Azo Root, we’re not just selling a product; we’re offering a cornerstone for advanced root health programs,” said Paul Giordano, Ph.D., director of agronomy for Harrell’s. “Our trials on golf courses and in nursery settings have consistently shown that Azo Root outperforms standard treatments, making it an essential addition for anyone looking to boost plant vitality and growth.”

Azo Root is now available exclusively through Harrell’s and can be integrated into existing soil management and spray programs due to its compatibility with other products.
