The Ministry of Agriculture and Farmers Welfare notified 34 Bio stimulants such as seaweed extracts, humic and fulvic acid formulations, among others.
They are notified under the Fertiliser Control Order (FCO), 1985.
In 2021, the bio stimulants were officially incorporated into the FCO, categorizing them as distinct class of fertilisers.
The Bio stimulants or Plant conditioners are natural or biological products that help plants grow by improving nutrient absorption and resistance to stress.
They do not include the pesticides or plant growth regulators, which are covered under the Insecticides Act, 1968.
