Crop application data
A leading oilseed and food legume worldwide, and the crop most exposed to aflatoxin — judged against some of the strictest safety limits in the food trade.
>80%
Less soil A. flavus on Orvan™-treated peanut in OCRI-CAAS field trials — alongside +19.9% average yield.
Two of peanut’s costliest problems strike at once: Aspergillus flavus contaminates kernels with aflatoxin, while nitrogen use stays inefficient, so growers pay for fertilizer and still lose value to contamination and trade rejection.
Peanut is a leading oilseed and food legume — but its biology puts it in harm’s way. The pods ripen underground, in direct contact with the soil, so the crop meets Aspergillus flavus exactly where the fungus lives, and the end-of-season heat and drought that stress the plant are when the fungus makes the most toxin.
Aflatoxin is a potent carcinogen, and the thresholds are unforgiving. A single contaminated lot can be downgraded or turned away at the border, so what is at stake is not a few points of yield — it is the value of the whole crop.
Peanut can fix much of its own nitrogen, but only when effective rhizobia are present and nodulation is strong. Where they are missing or weak — common on new ground — growers fall back on fertilizer, an added cost that, applied heavily, suppresses the very fixation it is meant to replace.
A crop-matched program led by the Orvan™ coupling, backed by a region-specific rhizobium (Nodu™) and phosphate-solubilizing, stress-tolerance PGPR (Vigor™). Each is field-proven and available on its own.
Rhizosphere coordination consortium
Aflatoxin–nitrogen coupling — applied alongside your rhizobial inoculant. Orvan™ carries no rhizobia of its own; it amplifies the ones already adapted to your soil.
Rhizobial inoculant
The region-matched, nitrogen-fixing rhizobia your crop needs — so it fixes more of its own nitrogen and you buy less.
PGPR — phosphorus & stress
Frees bound soil phosphorus, builds stronger roots, and buffers drought and salinity stress — the second leg of the consortium.

Orvan™ field trials · Peanut · vs. untreated control
Across 405 sites in 19 provinces (Henan, Shandong, Liaoning; 2021–2025): +19.9% average yield, >80% less soil A. flavus, up to 8.5× more nodules, and nitrogenase activity up to 10.7× — largest where native rhizobia are scarce or the variety is susceptible. A well-nodulated peanut crop can also leave nitrogen worth ~96 kg N/ha for the following cereal.
