Due to ongoing climate change, weather and seasons have become increasingly unpredictable, often leading to crop losses. Statistics show that 60% to 80% of crop yield losses are caused by abiotic stress; crop yields are high in good weather years and low in poor weather years. Bio-stimulants can effectively address these abiotic stress issues.

Indoleacetic Acid (IAA),Physiological Actions: Prevents plant senescence, maintains apical dominance, promotes parthenocarpy, induces phototropism, and promotes cell elongation and bending.Main Uses: Promotes rooting of cuttings; produces seedless fruit; promotes vegetative growth and reproduction, prevents flower and fruit drop, and increases yield; promotes seed germination; and induces callus and root formation in tissue culture.

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.
