When to Use Defend-Pro™
Defend-Pro is a biological fungicide able to attack threats already pressuring your crop or prevent problems before they start.
If your SFA report shows signs of biological imbalance, disease pressure, or stress in the root zone, Defend-Pro is your line of defense to create a more protective soil environment.
Growers often use Defend-Pro at planting to support emergence and early root health, especially in fields with a history of root disease, cold or wet conditions, or heavy residue.

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.
