Gibberellic is an important hormone that regulates development in higher plants and plays an important role in the growth and development of plants. It is used in crops such as potatoes, tomatoes, rice, wheat, cotton, soybeans, tobacco, and fruit trees to promote their growth, germination, flowering, and fruiting; It can stimulate fruit growth, improve seed setting rate, and have a significant yield increase effect on rice, cotton, vegetables, melons, fruits, and green manure.

Gibberellin powder:

Gibberellin powder is insoluble in water. When using it, first use a small amount of alcohol or Baijiu to dissolve it, and then add water to dilute it to the required concentration. The aqueous solution is easy to lose efficacy, so it should be prepared on the spot. It cannot be mixed with alkaline pesticides to avoid invalidation. For example, the purified gibberellin produced (1 gram per packet) can be dissolved in 3-5 milliliters of alcohol, then mixed with 100 kilograms of water to form a 10 ppm solution, and mixed with 66.7 kilograms of water to form a 15 ppm aqueous solution. If the content of the gibberellin powder used is 80% (1 gram per package), it should also be dissolved with 3-5 ml of alcohol, and then mixed with 80 kg of water, which is a 10 ppm dilution, and mixed with 53 kg of water, which is 15 ppm solution.

 Gibberellin aqueous solution:

Gibberellin aqueous solution generally does not require alcohol dissolution in use, and can be used after direct dilution. Cai Bao is directly diluted for use with a dilution ratio of 1200-1500 times the liquid.

Matters needing attention:

1. The application of gibberellin is carried out in weather with a daily average temperature of 23 ℃ or above, as flowers and fruits do not develop when the temperature is low, and gibberellin does not work.

2. When spraying, it is required to quickly spray a fine mist and evenly spray the liquid medicine onto the flowers. If the concentration is too high, it can cause the plant to elongate, albino, or even wither or deform.

3. There are many manufacturers of gibberellin in the market with inconsistent content of active ingredients. It is recommended to strictly follow the instructions for spraying when using it.

4. Due to the need for precise configuration during the use of gibberellin, special personnel are required to ensure centralized and unified allocation and use.
