What are the precautions for using growth regulators

Plant growth regulators are defined as non-nutritive organic substances that can influence the processes of plant growth and development at very low concentrations. In practical application, growth regulators include hormones and synthetic organic substances. Hormones refer to substances produced by the plant itself; therefore, hormones can also be called growth-regulating hormones synthesized by the plant body. Like all chemical agents, the effectiveness of a growth regulator is closely related to its formula, application concentration, the environment at the time of action (such as light intensity, humidity and temperature) and the plant species. First of all, it must be understood that a growth regulator being effective on one plant does not mean it will necessarily be effective on other plants. The timing of growth regulator application usually determines whether the desired effect can be achieved. If the timing is wrong, not only will the desired effect not be achieved, but adverse reactions may occur instead. The number of times a growth regulator is applied will also affect its effectiveness. Therefore, users need to understand how long a growth regulator persists in the plant body. Growth regulators can usually be mixed with other chemical agents such as fungicides, insecticides and herbicides, but before confirming whether a growth regulator can be mixed with other chemical agents, users must never mix and use them on their own. Otherwise, the effectiveness of the growth regulator will be reduced.
