Legislation on bio-preparations
Making bio-preparations for your own use is widely tolerated. The rules mainly concern placing on the market (sale, donation, transfer) and claims: what is promised about a product determines its legal regime. This page brings together the European, French and Spanish frameworks in a documentary summary.
Choose a country or territory to see the bio-preparation recipes authorised there, with a summary of the legal framework and the official texts.

Every recipe on the site has a regulatory status. Hover over or tap an icon anywhere on the site to see its definition. Here are the details.
| Icon | Status | Definition | Examples |
|---|---|---|---|
| ✅ | Authorised | The substance or recipe appears on an official list: EU basic substance (Article 23 of Regulation (EC) 1107/2009), PNPP in France, or a national list of inputs permitted in organic farming. The flags show the territories. | Horsetail, willow, whey, bicarbonate (EU); Bordeaux mixture (Brazil, Mexico); fermented plant juice (Philippines). |
| ⚠️ | Tolerated | Allowed only under conditions: certification body approval ('restricted'), maximum dose, limited use or crop, origin of the materials. | Copper: 28 kg/ha over 7 years in EU organic farming, 6 kg/ha/year in the Philippines and Morocco, 8 kg/ha/year in East Africa; manure: never from factory farming. |
| 🟠 | Not prohibited | No rule forbids it when it is made and used on your own farm. The rules cover sale and claims: no effect against pests or diseases is attributed to it and it is not sold without authorisation. | Farm-made liquid plant fertilisers (tithonia tea), manure ferments (jeevamrut). |
| ⛔ | Not authorised in the EU | No authorisation covers this farm-made preparation in the EU. It may be allowed in other countries: see the flags. | Neem decoction: not authorised in the EU, allowed in India, the Philippines, East Africa, Colombia… |
| 🔎 | Being verified | The regulatory status has not been validated yet. | New recipes under review. |
The same preparation falls under a different regime depending on what is claimed for it: feeding the plant (fertiliser), stimulating its natural processes (biostimulant) or protecting it against a pest or disease (plant protection product, subject to authorisation). A 'not prohibited' recipe remains so as long as it is not sold and no protective effect is attributed to it.

These rules apply to certified organic operators. Without certification, making preparations on the farm for your own use is generally not regulated; sale and claims, however, are regulated everywhere. Each country has its own 'authorised bio-preparations' page with its official texts.

The same product may fall under different regimes depending on what is announced to the user. The question is never "what is it?" in the abstract, but "what effect is claimed?".
| Claimed function | Applicable regime | Reference text |
|---|---|---|
| Feeding the plant | Fertiliser (PFC 1) | Regulation (EU) 2019/1009 |
| Improving the soil | Soil improver (PFC 3) | Regulation (EU) 2019/1009 |
| Stimulating the plant's natural processes | Biostimulant (PFC 6) | Regulation (EU) 2019/1009 |
| Protecting against a harmful organism | Plant protection product | Regulation (EC) 1107/2009 |
A product that claims action against a pest or a disease moves from fertiliser or biostimulant status to plant protection product status, which requires authorisation.
| Text | Subject |
|---|---|
| Regulation (EU) 2019/1009 | EU fertilising products (CE marking): fertilisers, soil improvers, growing media, biostimulants. Applicable since 16 July 2022. |
| Regulation (EC) 1107/2009 | Plant protection products, active substances, basic substances (Art. 23) and low-risk substances (Art. 22). |
| Regulation (EU) 2018/848 | Organic production and labelling of organic products. |
| Implementing Regulation (EU) 2021/1165 | Positive lists of products authorised for use in organic production (Annex I: plant protection; Annex II: fertilisers and soil conditioners). |
| Regulation (EC) 1069/2009 | Animal by-products: preparations based on bone, shells, blood or fish. |
| REACH and CLP Regulations | Chemical substances: registration, classification and hazard labelling. |
Basic substances (Article 23 of Regulation 1107/2009) are approved directly by the European Commission, for an unlimited period, and take effect in all Member States. Several common bio-preparation ingredients are among them:
Point of caution: sodium hydrogen carbonate (baking soda), often cited as a basic substance, is in fact approved as a low-risk active substance (Article 22, Implementing Regulation (EU) 2020/1263). The approval of a substance covers the uses described in its review report, not every use.
In France, most bio-inputs fall under the rules on fertilising materials and growing media (MFSC, Rural Code, Articles L255-1 et seq.). There are four routes to the market:
| Route | Description |
|---|---|
| NF U standard | Product covered by a French standard made mandatory (e.g. NF U 44-051 for organic soil improvers and composts). |
| CE marking | Product compliant with Regulation (EU) 2019/1009. |
| French AMM | Marketing authorisation (AMM) issued by ANSES. |
| Mutual recognition | Product already authorised in another Member State. |
PNPP (natural preparations of little concern) were created by Law No 2006-1772 of 30 December 2006 and are now governed by Article L253-1 of the Rural Code. "PNPP" covers two distinct regimes:
The case of nettle manure: sold without a plant protection claim, it has SNUB status; as soon as a protection claim appears, it falls under the simplified authorisation of the Order (arrêté) of 18 April 2011. One product, two regimes, depending on what is promised to the buyer.
| Authority | Role |
|---|---|
| Ministry of Agriculture (DGAL) | Regulatory texts, plant and animal health surveillance |
| ANSES | Assessment and authorisations (E-Phy database) |
| INAO | Organic farming |
| DGCCRF | Commercial and claims enforcement |
In Spain, fertilising products are governed by Real Decreto 506/2013 on fertilising products and Real Decreto 1051/2022 on the sustainable nutrition of agricultural soils, which creates the REGFER register (Registro general de fabricantes y otros agentes económicos de productos fertilizantes). Plant protection products are listed in the Registro Oficial de Productos Fitosanitarios of the Ministry of Agriculture (MAPA), pursuant to Regulation (EC) 1107/2009.
A product may be legal to sell and yet prohibited for a certified organic operator, and vice versa. Two conditions must both be met:
biopreparados.es is a documentary collection. The recipes and ingredient sheets describe traditional practices and the composition of preparations; they constitute neither a recommendation for use nor a plant protection or veterinary claim. Before any use, and all the more before any sale or transfer, check the regulations in your country.
Documentary summary up to date as of 9 October 2026, not legal advice. The precise status of a preparation depends on its composition and use, and must be checked case by case.
