Storage requirements for plant growth regulators mainly include the following points:
**Temperature control: Plant growth regulators should be stored within an appropriate temperature range. Most plant growth regulators should be stored in a dry place to avoid high temperature and humidity. For example, the aqueous solution of gibberellin is easily destroyed and ineffective above 5°C, so it should be stored in a dry place. In addition, most powdered pesticides are easy to melt, decompose, and volatilize at high temperatures, so the temperature should be kept above 1°C.
**Store away from light: Ultraviolet rays in sunlight may destroy the chemical structure of plant growth regulators and affect their effects. Therefore, plant growth regulators should be stored in a light-proof environment to avoid direct sunlight.
**Sealed storage: The container of plant growth regulators should be kept sealed to prevent oxygen, humidity or other pollutants in the air from entering, so as to maintain its purity and stability. For example, gibberellin cannot be mixed with alkaline pesticides or fertilizers because it is easily decomposed when it encounters alkali.
**Classification storage: Plant growth regulators of different properties should be stored separately to avoid mutual influence and deterioration. For example, alkaline pesticides and acidic pesticides should be stored separately, and the distance should be kept at more than 0.5 meters.
**Avoid mixing with food, feed, etc.: Plant growth regulators should be stored in special counters or wooden boxes, and avoid mixing with grains, oils, beans, seeds, vegetables and other foods to prevent misuse or contamination.
**Prevent children from contact: Because plant growth regulators are toxic to a certain extent, they should be stored out of reach of children, especially to prevent children from contacting them to avoid accidents.
