AMVAC, BASF Collaborate to Develop Rhizo-Flo Soybean Inoculant Solution for SIMPAS-applied Solutions

Newport Beach, CA

Rhizo-FloAMVAC® and BASF are pleased to announce a collaboration to develop Rhizo-Flo® granular soybean inoculant as an exciting addition to the expanding SIMPAS-applied Solutions™ portfolio.

Rhizo-Flo is a unique and leading soybean inoculant designed to deliver high concentrations of viable and effective Bradyrhizobium cells and ultimately improved yields. When Rhizo-Flo inoculant is utilized, the Bradyrhizobium sp. multiplies, penetrating the soybean plant root system to form nodules that allow the soybean plant to fix nitrogen. As growers strive to push soybeans to higher yields, Rhizo-Flo inoculant is another important tool the grower has available to achieve yield objectives and improve bottom line results.

Rhizo-Flo would join a growing portfolio of SIMPAS-applied Solutions (SaS), which are products prescriptively applied with patented SmartCartridge® container technology and using the SIMPAS® application system to address unique agronomic needs. Across the SaS portfolio are insecticides, nematicides, fungicides, micronutrients, and solutions for soil health and fertilizer efficiency. (See more about SIMPAS-applied Solutions below.)

“AMVAC is excited to collaborate with BASF to develop Rhizo-Flo for use as a SIMPAS-applied Solutions that can be applied with the SIMPAS system,” said Jim Lappin, Director of SIMPAS Portfolio and Alliances at AMVAC. “SIMPAS gives growers the flexibility to apply exactly what’s prescribed, precisely where it’s needed.”
