When to use Primepro-M™ + Defend Pro™
This powerful combination is key to a fast start and strong finish for your crop when early-season conditions suggest increased risk.
When cold soils, heavy residue, or lurking disease pressure threaten your crop at its most vulnerable time, it’s important to establish beneficial root-zone microbials with an extra layer of protection to maintain your farm’s productivity.

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.
Zach M.

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.
