Biological Seed Inoculants

SPE-120 (Organic Market) and SBb2.5 (Conventional and Non-GMO Markets) seed inoculants utilize Beauveria bassiana as an endophyte to form a symbiotic relationship with the plant and its environment. As the plant grows, B. bassiana grows with the plant to nurture this relationship. This symbiotic relationship elevates the plant’s natural ability to absorb nutrients, increase photosynthesis, and mitigate pathogens and other stressors.

Plants established a symbiotic relationship with B. bassiana millions of years ago. As cultural practices evolved over time, such as tillage and reliance on synthetic chemistry, this relationship has been compromised. By utilizing SPE-120 / SBb 2.5, you can restore that ecological partnership to help your crops reach their full potential.

For use on crops such as potato, field corn, sweet corn, soybean, cotton, sweet potato, small grains, rice, sugar cane, brassicas, dry beans, berries, tomato, fruit trees, onion, and grape. Contact us to learn more.

SPE-120 with Beauveria bassiana is a plant symbiont.

Activity includes:
  • Stimulation of immune system
  • Restricts plant pathogens from entering the plant
  • Interacts with plant to produce additive biochemicals
  • Combines plant resistance to insect feeders for reducing population threat
  • Naturally occurs in soil but has been killed off by fungicides and tillage
