Gibberellic acid is a broad-spectrum plant growth regulator that can promote the growth and development of crops, make them mature earlier, increase yields, and improve quality.

Insecticides: Gibberellic acid can be used to make high-efficiency, low-toxic insecticides that have certain killing effects on a variety of pests.

Herbicides: Gibberellic acid can also be used to make herbicides, which have good control effects on a variety of weeds.

Promote growth: An appropriate amount of gibberellic acid can promote the growth and development of plants, and improve plant stress resistance, immunity and yield. Therefore, gibberellic acid is also used in the production of plant growth regulators.

Preservatives: Gibberellic acid can prevent deterioration and spoilage of agricultural products during storage and transportation, extending their shelf life. Gibberellic acid is also a commonly used preservative in food processing and storage.

The main physiological effect of gibberellic acid (GA3) is to promote growth. For young cells in the meristem, its function is to promote division. For adult cells, its main function is elongation. Compared with auxin, the functions of gibberellic acid are as follows:
Acts on the whole plant;
It only makes the stem elongate without increasing the number of nodes;
The number of nodes can only be increased for stems with intervening meristems;
There is no inhibitory effect at high concentrations, and even at very high concentrations, it exhibits a strong growth-promoting effect;
It's just that when the concentration is too high, the plant form is abnormal;
Gibberellic acid can also promote nutrient transport, break seed dormancy, inhibit fruit tree flowering, inhibit flower bud differentiation, promote fruit setting, affect fruit maturity, and promote fruit development;
In most cases, it can inhibit organ aging;
Gibberellic acid can also affect the synthesis and action of other hormones and certain enzymes.
Gibberellic acid is a low-toxic plant growth regulator, low-toxic to humans and livestock, safe to fish and aquatic organisms, and has no mutagenic or carcinogenic effects.

1. This product can be mixed with general pesticides to synergize each other. If too much gibberellic acid is used, the side effects will cause lodging, so Fuquat is often used for adjustment. Note: It cannot be mixed with alkaline substances, but it can be mixed with acidic and neutral fertilizers and pesticides. Mixing with urea has a better yield increase effect.

2. The spraying time is before 10:00 am and after 1:00 pm. If it rains within 4 hours after spraying, spraying should be repeated.

3. The concentration of this product is very high. Please prepare it according to the dosage. If the concentration is too high, weeds will become overgrown, bleached, deformed or dead. If the concentration is too low, the effect will be insignificant. The amount of liquid used for leafy vegetables varies with the size and density of the crop. Generally, the amount of liquid used per acre should not be less than 50 kilograms each time.

4. Gibberellic acid aqueous solution is easy to decompose and should not be stored for a long time. It should be prepared and used immediately.

5. The use of gibberellic acid can only play a good role when fertilizer and water are supplied, and cannot replace chemical fertilizers.

6. Spraying gibberellic acid should be carried out when the daily average temperature is above 23, because when the temperature is low, flowers and fruits do not develop, and gibberellic acid does not work.

7. When spraying, it is required to spray the liquid evenly on the flowers. Excessive concentrations can cause plants to overgrow, turn white, and even die or become deformed.
