AGROCHEMICAL & PESTICIDES - Plant Growth Regulator Registration

Cultivating Growth Together

Plant regulators also known as Plant Growth Regulators or Phytohormones or Plant Hormones are natural or synthetic substances that play a vital role in regulating various aspects of plant growth and development. Plant growth regulators (PGRs) are organic compound other than nutrients that effect the physiological process of promoting, inhibiting or modifying growth and development in plants when applied in low concentration. These act as chemical messengers within plants, controlling processes such as cell division, elongation, differentiation and flowering. They are applied directly to a target plant to alter its life processes or its structure to improve quality, increase yields etc.
Plant growth regulators (PGRs) are chemicals used to modify plant growth such as increasing branching, suppressing shoot growth, increasing return bloom, removing excess fruit, or altering fruit maturity.

PGRs along with pesticides are regulated under the Insecticides Act, 1968 (46 of 1968). It is not categorised as a fertiliser.

  • Growth regulators can be used to promote or inhibit certain aspects of plant growth, such as flowering or fruit development.
  • Improving crop yields
  • Controlling weeds
  • Enhancing the appearance of plants

To understand PGR regulations, it is important to first understand the terminologies associated with it.

Meaning of Terms- TIM, TI, FIM, FI
  • Technical Import (TI): Import of technical insecticide for manufacture of formulated insecticide.
  • Technical Indigenous Manufacture (TIM): Manufacture of technical insecticide in India.
  • Formulation Indigenous Manufacture (FIM): Manufacture of formulation from technical insecticide manufactured in India or from imported technical.
  • Formulation Import (FI): Formulations, which are to be directly imported to India in finished form for direct marketing.


PGRs are broadly classified into two major groups:

Plant Growth Promoters
  • Auxins
  • Gibberellins (GA)
  • Cytokinins
Plant Growth Inhibitors
  • Ethylene
  • Abscisic Acid (ABA)

Can Help?

Expertise in agrochemicals is categorized into three broad areas: human health, environmental health, and chemistry. In each, our associate specializes in areas such as toxicology, environmental chemistry and risk assessment. Our associate regulatory specialists concentrate on specific regulated areas in their respective geographies and provide consultancy services to help you with every step of the regulatory framework process.

Plant Growth Promoters & Plant Growth Inhibitors

Plant Growth Promoter

  • The plant growth regulator or hormones which have catalytical effect i.e. take a vital role in plant growth.
  • Examples: Auxins, Gibberellins (GA), Cytokinin, etc.

Plant Growth Inhibitor

  • The growth regulators which selectively interfere with normal hormonal promotion of growth of the plant without appreciable toxic effects.
  • Examples: Malichydrazide (MH), Benzonic Acid, Chlormequat (Chlorocholine) Chloride (CCC), B-9, Triodo Benzoic Acid (TIBA), Abscisic acid (ABA), Chlorpropham (CIPC) etc. act as growth retardants.


Permanent Registration u/s 9(3)

All the studies are completed first and then the final dossier is submitted.

Registrations for:

  • Technical Indigenous Manufacture (TIM)
  • Technical Import (TI)
  • Formulation Indigenous Manufacture (FIM)
  • Formulation Import (FI)
  • Technical Import (TI) from New Source
  • Formulation Import (FI) from New Source

Repeat or ‘Me Too’ registration u/s 9(4)

Anyone wanting to deal in PGR, claiming the chemical equivalence to already registered products.

Where a PGR has been registered on the application of any person and some other person desires to manufacture or import the same insecticide or engage in the business of import or manufacture thereof shall be granted a Certificate of Registration on the same conditions on which the PGR was originally registered.

  • Technical Import (TI);
  • Formulation Import (FI);
  • Technical Indigenous Manufacture (TIM);
  • Formulation Indigenous Manufacture (FIM).

Provisional Registration u/s 9(3B)

Where the PGR is being introduced for the first time in India, it is registered provisionally for a period of 2 years. During provisional registration, the distribution or sale of such pesticides shall not be permitted. It includes first time introduced:
  • Technical Import (TI)
  • Formulation Import (FI)
  • Technical Indigenous Manufacture (TIM)
  • Formulation Indigence Manufacture (FIM)


  • Conducting a feasibility study;
  • Pre-registration analysis of data;
  • Applying for Research, Test and Trial (RTT)- We guide you to bring your active ingredient or product in India for certain testing requirements or at the time of efficacy data generation. Obtaining a successful RTT permit is a major accomplishment, marking the outset of our regulatory compliance journey;
  • Registration and Data generation as per CIB guidelines- We work closely with GLP (Good Laboratory Practice) labs and consistently communicate with the scientists at (Contract Research Organisations). We rigorously examine the data before presenting it to the appropriate authorities.
  • Separate application shall be made to CIB & RC for each such PGR;
  • Dossier Submission;
  • Scrutiny by CIB & RC;
  • Approval by CIB&RC and issuance of Registration Certificate;
  • State Regulatory compliance for approval to sell.
  • BIS and FSSAI compliance, wherever required.
  • A manufacturer, who holds a valid Certificate of Registration granted by CIB & RC is also required to obtain License in Form- II from the Licensing Officer of the concerned State Government for manufacturing the PGR;
  • The manufacturer shall meet requirements relating to qualifications, infrastructure, manufacturing premises, storage and transport etc.
  • Any person desiring to only sell, stock or exhibit for sale or distribute any PGR shall make application in Form- II to the Licensing Officer of the concerned State Government for the grant of a license;
  • If any PGR is proposed to be sold or stocked for sale at more than one place, separate applications shall be made in respect of every such place;
  • The seller must procure PGR from a valid holder of Certificate of Registration;
  • Obtaining license is a State subject matter and differs from State to State.
  • Persons seeking to import PGR are required to obtain a Certificate of Registration from the Registration Committee constituted by Central Government;
  • No person shall import any pesticide which is misbranded, whose sale, distribution or use is prohibited u/s 27, any PGR other than conditions specified or in violation of any other provision.
  • Central Insecticides Board & Registration Committee (CIB&RC)
  • Respective State Governments
Before data generation, the applicant should ensure that the requirements are being complied correctly for the type of PGR to be registered under the desired category and for the intended purpose.
Following should be clear before data generation:
  • Type of PGR to be registered;
  • Type of material to be registered i.e. Technical or Formulation or Manufacturing Use Product (MUP) etc.,
  • Type of formulation i.e. Solid (WP, granules, powder) etc. Liquid (EC, EW, SC etc.) or Vapor (vaporizer, fumigants etc.);
  • Category of registration i.e. Provisional [u/s 9(3B)], Permanent [u/s 9(3)] or Me-too [u/s 9(4)];
  • Purpose of registration- Domestic use/Import/Export;
  • Intended use of the PGR to be registered and its label claims etc.
