Stimulant additives are typically synthetic auxin, cytokinin, or retardant analogues (e.g. IBA for rooting, CCC/DPC for controlling internode elongation) used to shape plant architecture or accelerate a specific developmental transition — distinct from biostimulants, which support general stress tolerance rather than directing a specific hormonal response.
12 products are listed in this category, all in the Gold tier. Gold-tier formulations are specified by composition. The range covers 2-Naphthoxyacetic Acid (BNOA), 3-Indolebutyric Acid (IBA), 3-Indolyl Acetic Acid (IAA), Brassinolide, Chlormequat Chloride (CCC), Chlormequat Chloride (CCC) 50%/75% AS, CPPU(KT-30) Cytokinin, DA-6 1.6% AS, Gibberellic Acid GA3, Mepiquat Chloride (DPC) 250g/L, Potassium 3-Indolebutyrate (IBA-K), Sodium Nitrophenolate 1.8% AS (Atonik). Pack sizes listed for these products: 1 kg, 5 kg, 25 kg. Each product page gives its specifications and packaging, and controlled copies of the TDS and SDS are supplied for the requested market and formulation.
Part of the Plant Growth Regulators range. Growth regulators work by enhancing a plant's natural hormone signals — auxins to stimulate rooting, cytokinins to boost cell division, and gibberellins to promote elongation. They are highly effective for optimizing crop developmental timing and shaping plant architecture when applied at key growth stages.

2-Naphthoxyacetic Acid (BNOA)
BNOA — Fruit Set & Pre-Harvest Drop Reduction

3-Indolebutyric Acid (IBA)
IBA — Standard Rooting Hormone for Cuttings & Transplants

3-Indolyl Acetic Acid (IAA)
IAA — Natural Auxin for Apical Dominance & Tropic Response

Brassinolide
Brassinolide. A brassinosteroid — a distinct hormone class from auxins/gibberellins/cytokinins — that promotes cell division and elongation while also enhancing tolerance to cold, drought, and salinity stress.

Chlormequat Chloride (CCC)
CCC — Anti-Lodging Growth Retardant for Cereals & Ornamentals

Chlormequat Chloride (CCC) 50%/75% AS
Chlormequat Chloride — Growth Retardant for Lodging Control

CPPU(KT-30) Cytokinin
CPPU. A synthetic cytokinin (also known as KT-30/forchlorfenuron) that drives cell division and is specifically associated with significant fruit-size increases — most established in kiwifruit and grape.

DA-6 1.6% AS
DA-6 Growth Regulator — Photosynthesis and Vigor

Gibberellic Acid GA3
Gibberellic Acid GA3. The base gibberellin hormone: promotes cell elongation and can break seed or bud dormancy. Response is dose-sensitive — excessive rates risk stem elongation and lodging.

Mepiquat Chloride (DPC) 250g/L
Mepiquat chloride (DPC). A growth retardant with the same gibberellin-inhibition mechanism as chlormequat chloride, most widely used in cotton to control excessive vegetative growth and improve boll retention.

Potassium 3-Indolebutyrate (IBA-K)
IBA-K — Higher-Solubility Potassium Salt of IBA

Sodium Nitrophenolate 1.8% AS (Atonik)
Sodium Nitrophenolate (Atonik) — Metabolic Biostimulant
