The shelf life of plant growth regulators is usually 2 years. Specifically, the shelf life of mepiquat is generally 2-3 years, but it must strictly follow the storage conditions such as light avoidance, sealing, cool and dry, and avoid high temperature or humid environment. The shelf life of 2,4-D sodium salt is 2 years. When using it, it should be noted that it is used as a plant growth regulator at low concentrations and as a herbicide at high concentrations. The shelf life of other plant growth regulators such as Brassinolide, Azenmei® and Vital is also 2 years.
When using plant growth regulators, you need to pay attention to the following points:
Storage conditions: It should be stored in a cool and ventilated place, avoid direct sunlight, control the temperature between 0-30℃, and keep the container sealed to prevent mixing with alkaline substances or other pesticides.
Usage: Strictly dilute according to the recommended concentration. Excessive use may inhibit plant growth. Wear gloves, masks and other protective equipment when applying to avoid direct contact with the skin or inhalation.
Expired disposal: If the liquid is found to be stratified, crystallized or precipitated, it may have expired and is not recommended for continued use. Expired drugs must be disposed of in accordance with local environmental regulations and must not be dumped or incinerated at will.
