Microbial inoculant questions

Product applications cover fruit and berry crops, vegetables, and field and forage crops. Examples include citrus, grapes, strawberries, blueberries, tomatoes, peppers, cucumbers, lettuce, soybean, peanut and alfalfa. Legume inoculants are one part of this broader portfolio. Product selection and use depend on the crop, growing conditions and market-specific product documents.

The website presents selected product information. You can also enquire about agrochemicals, biological inputs and crop nutrition that are not listed. Share your product requirements and destination market so we can discuss specifications, available documentation and supply arrangements.

The portfolio covers crop protection, crop nutrition, biostimulants and microbial inoculants. Agrochemicals and biological products address weed, disease, insect, mite and nematode management. We supply distributors, agri-input companies and large farms, carry out product registration, and work with universities and research institutes to turn new technologies into products ready for supply.

Huasheng Bio is a Chinese agricultural-input company founded in Beijing in 2021. Its products are sold in more than 30 countries and regions.

Huasheng combines its own production with partner manufacturers in China. This allows a broad portfolio, and every product, whichever route it takes, is supplied to the same agreed specification, acceptance criteria and batch documents.

Huasheng Bio has offices in Hong Kong, Beijing (Tongzhou and Changping), Yantai (Shandong) and Duarte, California. The Hong Kong office is at 4/F, Cyberport 2, 100 Cyberport Road, Pok Fu Lam, Hong Kong; the other addresses are listed on the contact page.

Partnerships can involve technology licensing, joint development, market introduction or brand arrangements. We first review the technical records, agree the target market, rights and each party’s role, then define the trials, development work or market introduction plan.

Start with your destination market, crop, growing system and the problem to address. Review ingredients, formulations and technical records alongside local labels, application methods and current crop management. For sourcing, include expected quantity, packaging and delivery timing so we can review supply conditions.

Product pages include technical information, available documents and relevant scientific background. Crop-specific studies and field records, where available, identify the product and conditions studied.

Use the product-page enquiry link; the form carries your selection. We review which specifications, technical profiles and safety documents are available. For samples, agree the formulation, quantity, evaluation purpose and destination requirements, and identify the sample version and batch for later comparison.

The review covers the agreed product specification and quantity, packaging, label version, batch identification and order documents. Batch analysis must relate to the material supplied. Delivery timing, shipping terms and the documents needed at destination are confirmed with the order.

Send the order reference, product and batch identification, the issue observed and relevant photographs or test records. For an application question, include crop, timing, dose and any mixed products. This lets the team distinguish shipment, storage, formulation and application questions and review the records with the relevant partner.

No — Orvan™ is complementary and amplifies the rhizobia already in your soil or inoculant.

No. All strains are naturally isolated; no genetic modification.

No. Orvan™ contains no fungi at all — its three strains are bacteria: Bacillus velezensis, Brevibacillus laterosporus and Paenibacillus mucilaginosus. The published science it is built on is named Aspergillus–Rhizobia Coupling (ARC) after two changes measured together in the root zone: in multi-season OCRI-CAAS field trials, treated peanut showed markedly lower soil Aspergillus flavus alongside a stronger rhizobial symbiosis. Whether the two are causally linked, and by what mechanism, is still being worked out. The name describes what is measured in the soil, not what is in the bag — Orvan™ carries neither organism.

Eight legumes — peanut, soybean, common bean, cowpea, pigeon pea, mung bean, black gram, alfalfa — with multi-site field results on all eight (peanut and soybean have the largest datasets).

Rhizobia are region-specific. Nodu™ is matched to local populations and confirmed before deployment; Orvan™ amplifies your soil’s native rhizobia, so it fits local conditions.

At sowing — granule, in-furrow liquid, or seed treatment — matched to your planter.

Yes, within a tested list. On seed, Orvan™ co-applies with the fungicide classes used in seed treatment (oomycete fungicides, benzimidazoles, triazoles, phenylpyrroles, strobilurins) and with thiamethoxam, clothianidin, imidacloprid and chlorantraniliprole, as well as with rhizobial inoculants and NPK. It is not compatible with anything registered against bacterial disease: copper compounds, thiazoles, quinolines and agricultural antibiotics. Chlorinated water above 2 ppm and pH above 9 should also be avoided. The order matters: a fungicide seed treatment goes on first and is left to dry, then Orvan™, then any rhizobial inoculant. The full list is on the Orvan™ page; outside it, apply sequentially rather than premixed.

Non-GMO, BSL-1, no synthetic pesticide; no residue concerns under tested conditions.

6 to 18 months depending on formulation, stored cool and dry — around 6–8 months for the rhizobial and PGPR liquids, 18 for the Orvan™ granule, longer for the freeze-dried form. The date on the pack is the one that counts.

Formulations are made without GMOs, synthetic pesticides, or animal-derived carriers; organic acceptability is jurisdiction-specific (NOP / EU 2018/848 review).

Yes — peer-reviewed research plus multi-season field trials; full data packages to qualified partners under NDA.

A peanut inoculant is a formulated product that delivers live Bradyrhizobium to the seed or furrow, so peanut (groundnut) roots nodulate and fix their own nitrogen. Nodu™ supplies region-matched rhizobia for that job, and our Orvan™ consortium amplifies those rhizobia to build stronger nodulation and nitrogen fixation — so the crop fixes more of its own nitrogen and you buy less.
