Biological Seed Treatment

Soil and Plant Enhancer (SPE-120) with active ingredient Beauveria bassiana, is a natural, symbiotic fungus that lives in the soil, roots, stems, and leaves. SPE-120 grows with the plant!

Conventional seed treatments using neonicotinoids or other synthetic chemicals have a finite amount that can fit on the seed. They become less effective as the plant grows and are not compatible with nature.

SPE-120 blends food grade and certified organic products with Beauveria bassiana. Many certifiers have determined compliance with organic standards. Contact your certifier to add SPE-120 to your plan.
