How to Use Plant Growth Regulators Correctly (Dosage and Application Methods)
Why Does the Use of Growth Regulators Fail Despite Choosing the Right Product?
Many farmers choose the right plant growth regulator but still do not achieve the expected results.
In most cases, the issue is not the product itself.
It is the way it is used.

Incorrect use leads to weak or even negative results.
Correct use leads to a clear improvement in yield and quality.
