More about this list
About this list
India regulates biostimulants under Schedule VI of the Fertiliser (Inorganic, Organic or Mixed) (Control) Order, 1985. Each product is notified in the Gazette with its composition, its specifications, and the crops and doses it may be sold for. Those details are spread over a dozen notifications and many PDF pages; here they are in one place, one page per product.
The list follows the latest wording: when a later order substitutes an entry or changes a crop, dose or figure, the page shows the amended text and says so. Per-acre figures are conversions from the notified per-hectare dose; the Gazette dose is always the controlling one.
Covers notifications up to S.O. 1574(E) of 25 Mar 2026. Checked for later Schedule VI changes on 19 October 2026. A reference consolidation by NanoKheti, not legal advice; confirm with the official notifications before labelling, licensing or buying.

Questions
How many biostimulants are notified under FCO Schedule VI?
226 product entries in 11 categories, as consolidated from the Gazette notifications up to S.O. 1574(E) of 25 Mar 2026. One serial number (Antioxidants, serial 2) has been used for two different products, so there are 225 category and serial numbers. The largest groups are mixed formulations (58), seaweed extracts (53), protein hydrolysates and amino acids (36) and humic and fulvic acids (34).
How do I convert a per-hectare biostimulant dose to per acre?
Divide the per-hectare dose by 2.47105, because 1 hectare is 2.47105 acres. For example, 750 ml per hectare is about 304 ml per acre. One acre is 40 guntha. Each product page has a calculator for acres, hectares and guntha; the Gazette per-hectare dose is always the controlling figure.
Which biostimulants were removed from Schedule VI?
S.O. 4441(E) of 29 September 2025 omitted 14 entries: 3 mixed formulations and 11 protein hydrolysates, most of them of animal source. They are listed at the end of this page and are not part of the current list.
Is this the official list?
No. NanoKheti consolidated it from the Gazette notifications so that the details are easy to find and compare. The Gazette text is authoritative: check the notification before you label, license or buy a product.
What does a product page show?
The notified composition, the specifications (label claims) with the Part D test method for each, the crops and doses exactly as notified, per-acre conversions, any mandatory label caution, later amendments and the notification history.
