Mycorrhizal Fungi
Form beneficial relationships with plant roots to expand nutrient and water uptake beyond the root zone.
Primepro-D | Liquid
Start Strong. Finish Stronger.
Formulated specially for dicots, Primepro-D™ delivers beneficial microbes at planting, supporting nutrient uptake, root development, and early plant resilience.
Speeds emergence and improves early plant vigor.
Helps plants access phosphorus, micronutrients, and nitrogen more efficiently.
Builds root zone biology early for season-long performance.
What it Does
Primary Function
Expands Root Systems and Establishes Symbiotic Biology
- Symbiotic nutrient exchange
- Rhizosphere establishment
- Early-season biological activity
- Root expansion processes
Pathways Opened
- Root development pathways
- Water uptake pathways
- Nutrient exchange pathways
Field Impact
- Enhances early root development and vigor
- Improves nutrient and water uptake efficiency
- Supports stronger biological establishment in dicot crops
- Increases tolerance to environmental stress
When to use Primepro-D™
A strong start is the best start for your crop and ultimately leads to a stronger finish.
Primepro-D is designed for dicot crops—especially soybeans and other legumes—where early root development and nutrient access set the tone for the entire season.
Growers use Primepro-D to improve stand establishment, support nitrogen availability, and help crops handle early-season stress.

Customer Reviews
BTI products are easy to use. They’re tank mix compatible, so our customers aren’t making separate passes to use the products. This has made BTI easy to incorporate into their businesses.

BTI has really changed the way we think about the crop in general—whether that’s below-ground soil fertility, soil health, or above-ground plant health.

We couldn’t keep competing the same way. We needed a whole new hand of cards. When you think microbial, that resets the whole paradigm for you.
