Guard-N®

Premium Legume Inoculant



Fix more nitrogen with a legume inoculant for enhanced growth

Guard-N® is a legume inoculant that helps improve nitrogen uptake in common garden crops, including beans, peas, lima beans, soybeans, and 60 other species.

Guard-N® is Organic Materials Review Institute (OMRI) listed for organic use and contains several strains of rhizobia, including Bradyrhizobium japonicum, Bradyrhizobium sp. (Vigna), Rhizobium leguminorsarum biovar viceae and Rhizobium leguminosarum biovar phaseoli. These symbiotic nitrogen-fixing bacteria help legumes capture more nitrogen, giving them the boost they need for a strong start and successful season.

Guard-N® Inoculant Guidelines

Always read and follow label instructions and restrictions before use.

Legume Inoculant Application Instructions

Guard-N can be applied by using either the slurry or sprinkle method; however, the slurry method will result in better seed adhesion by the inoculant. Re-inoculate seed if not planted within 24 hours of application. Use only on specified legumes designated on the label.

Application Rate (oz/lb)
1 lb 5 lb 8 lb
0.2 oz 1.0 oz 1.5 oz
