The use of plant growth regulators in the agricultural sector is generally carried out for the following purposes:

• Improve germination power of seeds
• Encourage or delay plant flowering
• To ensure proliferation with steel
• Increasing the plant's resistance to cold
• To increase seed formation in fruits
• To make the fruits bigger
• Extend the preservation period of the fruit
• Increasing the resistance of plants against diseases and pests
• Weed control
• Preventing bed in cotton and grains
• Preventing fruit spills before harvest
• Accelerate maturation
• To ensure the ripening of plants simultaneously for machine harvesting
• Reduce the labor force at harvest

Plants themselves provide the necessary substances for growth and growth. These substances that regulate the growth and development of plants are called plant hormones. In order to qualify a compound as a plant hormone, it must form in the plant, be transported from one location to another, manage or regulate different physiological events at the site of transport, and show these effects even at very low concentrations.

Ethylene is the leading natural growth regulator. Ethylene is the most widely used plant hormone in the world. Ethylene is followed by auxin. Auxins are a growth regulating agent that promotes growth. Ethylene is more effective in the ripening of fruits.

These compounds, which are not found in plant nature, should not be mixed with natural hormones. These compounds, which are not in the plant and show very low hormone effects, are synthetic hormones. In order to avoid confusion, the substances that have hormone effect in plants are called plant growth regulators.

In the laboratories, the regulatory determination of plant growth is also made within the scope of chemical tests. Liquid Chromatography - Mass - Mass Spectrometry (LC-MS / MS) method is also used in these studies. The LC-MS / MS instrument has been developed for qualitative residue analysis applications. It gives high speed and accuracy results. During these analyzes, the standards issued by domestic and foreign organizations are also taken as basis.
