Plant growth regulators are pesticides, which have strict technical requirements, such as use period, dosage, use method and so on. It must be used according to the instructions, otherwise it will have adverse consequences. The effect of plant growth regulator is generally obvious, stable and less affected by environmental conditions, so it can be popularized and applied quickly and is easy to be accepted by users. It is a kind of synthetic organic compounds with plant natural hormone activity. According to their different regulatory effects on crops, they can be divided into two categories: (1) those that promote growth, such as 920, 802, ethephon, and (2) those that control growth, such as paclobutrazol, dwarf, metoprolol, etc. Plant growth agent plant growth agent is fertilizer, also known as plant nutrition agent, plant compound liquid fertilizer and so on. It is a kind of nutrients made of nitrogen, phosphorus, potassium, iron, zinc, manganese, boron, copper and other trace elements together. Most of them are foliar fertilizer spraying to supplement nutrients to promote crop growth and development when crop roots do not absorb water and fertilizer badly.
