Ethephon - Introduction
Ethephon is a common plant growth regulator commonly used to promote plant growth and improve the yield and quality of crops. Here are the details of ethephon:
Nature:
Ethephon is a colorless to light yellow liquid with a peculiar odor. It has low toxicity and volatility.
Use:
Ethephon is widely used in agriculture and horticulture. The Main uses include:
1. Promote plant growth: Ethylene can improve plant growth vigor, increase yield and fruit quality.
2. Control plant growth: Ethephon can delay the growth rate of plants, make crops grow more evenly, and facilitate management and harvest.
3. Stress resistance enhancement: Ethylene can improve the resistance of plants to adversity (such as diseases and insect pests, drought and salinity, etc.).
Preparation Method:
Ethephon is mainly obtained by chemical synthesis. A common method of preparation is the reaction of Vinyl Bromide and vinyl ether under alkaline conditions to produce ethephon.
Safety Information:
In the case of correct use, ethephon is relatively safe. However, the following safety measures still need to be followed:
1. When using ethylene, wear appropriate personal protective equipment, such as gloves, glasses and respiratory protection.
2. Avoid direct contact with ethephon, especially skin and eyes. If accidentally contact, should immediately rinse with plenty of water, and timely medical treatment.
3. In the storage and handling of ethylene, should be away from the fire and high temperature environment, to avoid the risk of fire and explosion.
4. When using ethylene, please carefully read and follow the instructions and safety warnings on the product label.
