Environmentally friendly plant growth regulators are generally divided into two categories:1. Natural plant endogenous hormones or their analogs;2. Regulators extracted from natural substances or obtained through microbial fermentation. These are generally readily degradable in the environment and have low toxicity to non-target organisms (such as bees and birds).

When addressing the challenges of crop growth in autumn and winter, we often encounter plant growth regulators such as brassinolide, DA-6, and sodium nitrophenolates. While these agents all promote crop growth, their properties and recommended dosages vary. Different regulators have different promoting effects and dosages. Brassinolide, DA-6, and sodium nitrophenolates each have their own characteristics and optimal concentrations.

What are Plant Growth Retardants?Plant growth retardants are a class of chemical substances that inhibit plant growth, elongation, and development and promote proline accumulation. Plant growth retardants are commonly used in agriculture and horticulture to regulate plant growth and development rates, ensuring the quality and yield of crops or garden plants.

In horticultural crop cultivation, a wide variety of plant growth regulators are used, exceeding 40 types. For example, plant growth promoters include Gibberellic Acid (GA3), Naphthyl Acetic Acid (NAA), Indole Acetic Acid (IAA), Indole-3-Butyric Acid (IBA), and 2,4-D; plant growth inhibitors include abscisic acid
