Content and usage concentration of Gibberellic Acid GA3

Gibberellic Acid (GA3) is a plant growth regulator that has multiple physiological effects such as promoting plant growth and development, increasing yield and improving quality. In agricultural production, the usage concentration of Gibberellic Acid (GA3) has an important impact on its effect. Here are some detailed information about the content and usage concentration of Gibberellic Acid (GA3):

Content of Gibberellic Acid (GA3): The original drug of Gibberellic Acid (GA3) is usually a white crystalline powder, and its content can reach more than 90%. In commercial products, the content of Gibberellic Acid (GA3) may vary, such as soluble powders, soluble tablets or crystalline powders with different concentrations such as 3%, 10%, 20%, 40%. When purchasing and using Gibberellic Acid (GA3), users should pay attention to the specific content of the product and adjust the usage concentration accordingly.

Concentration of Gibberellic Acid (GA3):
The concentration of Gibberellic Acid (GA3) varies depending on its purpose.
For example, when promoting fruit setting of cucumbers and watermelons, 50-100 mg/kg of liquid can be used to spray the flowers once;
When promoting the formation of seedless grapes, 200-500 mg/kg of liquid can be used to spray the fruit ears once;
When breaking dormancy and promoting germination, potatoes can be soaked in 0.5-1 mg/kg liquid for 30 minutes, and barley can be soaked in 1 mg/kg liquid.
Different crops and different growth stages may require different concentrations, so in actual applications, the appropriate concentration should be determined according to the specific situation and product instructions.

In summary, the content and concentration of Gibberellic Acid (GA3) are two different concepts. Users should distinguish them when using Gibberellic Acid (GA3), and choose and use them reasonably according to actual needs and product instructions.
