Plant growth regulators (PGRs) can play a crucial role in regulating various physiological processes in plants, including growth, development, and stress responses. While not all PGRs are supplied in micronized form, some may be micronized to improve their dispersibility, solubility, and effectiveness. Here are some common plant growth regulators that may be supplied in micronized form:
| CHEMICAL NAME | BENEFITS | APPLICATION METHOD |
| Auxins Indole-3-acetic acid (IAA) | Cell elongation Root initiation Fruit growth | Rooting powders Hormone treatment |
| Cytokinins 6-Benzylaminopurine (6-BAP) | Cell division Shoot initiation Chloroplast growth | Tissue culture media Foliar spray |
| Gibberellins Gibberellic acid (GA3) | Stem elongation fruit development Seed germination | Seed treatment Foliar spray |
| Abscisic Acid (ABA) | Stops seed germination Stomatal closure Drought tolerance | Micronized ABA formulations may be used to regulate seed dormancy or induce stress responses in plants |
| Brassinosteroids Brassinolide (BR) | Cell elongation, Stress tolerance Flowering | Foliar sprays Seed treatment |
| Jasmonates Methyl jasmonate (MeJA) | Defence responses Wound healing Metabolite production. | Micronized jasmonates may be used to stimulate plant defences against pests and pathogens or to enhance the production of phytochemicals in crops |
These are some examples of plant growth regulators that may be supplied in micronized form for specific applications. Micronization can enhance the dispersibility, solubility, and effectiveness of PGRs, leading to improved plant responses and overall growth and development. However, the availability of micronized formulations may vary depending on factors such as regulatory approval, market demand, and application requirements.
