Symbiotic microbes
Stronger crops, acre after acre.
Two living microbial inputs that raise yield, strengthen crops against drought, heat and salinity, and help the crop access more of the nutrients available to it.
The Science
The health of every crop starts with microbiology.
Symm optimizes this relationship, so your crop grows the way nature intended.
Research backed and measured in the field.
Plants and soil microbes have partnered since the first roots reached into the ground. Symm builds on that ancient relationship, using well-studied microbes to strengthen the biology already at work beneath your crop.
What holds up in the study holds up in the row.
- Peer-reviewed
- Built on independent research into beneficial soil microbes.
- Two-part biology
- Resilience for the plant and nutrition unlocked from the soil.
Two parts, one program.
Two living blends, each with a distinct job, run together as a single program for the whole crop.

Resilience from within
Part 1
Stress resilienceContains
- Trichoderma harzianum
Part 1 is a living consortium of advanced Trichoderma harzianum strains, symbiotic fungi that partner with the plant itself. Working from within, they raise the crop's tolerance to stress so it keeps performing when conditions turn against it.
- Built for stress. The fungi help the crop push through drought, heat and salinity so growth holds steady when it matters most.
- A consortium, not a single strain. A blend of advanced strains covers far more conditions than any one microbe can, which is what sets it apart from off-the-shelf, single-strain products.
- Sets up the season. More resilient, better-supported plants lay the groundwork for the rest of the season. The difference is modest in a mild, well-supplied year and widens substantially under drought, salinity or extreme heat.

- Bacillus licheniformis

~1×10⁸ CFU/g each
Part 2 is a five-strain Bacillus consortium, beneficial bacteria that unlock nutrients already present in your soil and help the plant use them more efficiently. The result is more of what is already there reaching the plant.
- Unlocks your soil. Five complementary Bacillus strains free up nutrients and minerals that are present but out of reach, putting them back to work for the crop.
- Compounds with Part 1. A more resilient crop makes fuller use of what Part 2 unlocks, which is why the two are always run together as one program.

Always sold together as one program. One protocol, two parts.
How it works
Simple to run.
01
Order the program
Set your acreage and order online. Both parts ship together, matched to your coverage.
02
Apply the two parts
Both parts apply the same way, at seed, in-furrow, or as a foliar spray, on your normal schedule.
03
Grow and measure
Track your yield across the season, side by side against an untreated strip on the same field.
Reliability, batch by batch.
Biological inputs are only as effective as what actually survives long enough to be applied in field.
01 · Formula
Built on microbiology
Symm’s living organisms are studied and cultivated by microbiologists who specialize in them, living biology, not synthetic chemistry.
