Formulations of Gibberellic Acid Ga3 Development Tendency

Gibberellin acid is a class of chemical substances with high physiological activity, which have a great impact on the growth and development of plants and some physiological processes. A wide variety.

Variety formulations of Gibberellin acid GA3 have been widely used in agriculture, forestry, and horticulture, and have significant effects on breaking seed dormancy, promoting stem and leaf growth, early flowering, and fruit enlargement.

The effective ingredients of gibberellic acid formulations are mainly GA3 and GA4 + 7, and few other types of gibberellic acid are used in actual production.

Gibberellic acid can be dissolved in alcohols, acetone, ethyl acetate, butyl acetate, glacial acetic acid, and pH 6.2 phosphate buffer. It is hardly soluble in water and insoluble in solvents such as petroleum ether, benzene, and chloroform.

The current gibberellic acid formulations are mainly emulsifiable concentrates, crystalline powders, and soluble powders. Pesticide registration and management agencies in more and more countries require pesticide formulations to be safer for users, have less impact on the environment, and use lower dosages. These requirements have promoted the development of pesticide water-based formulations such as SC, EW, ME, and CS.

Gibberellin TC

Gibberellin crystal powder is produced by a series of filtration, concentration, extraction, and crystallization of gibberellin fermentation broth. Gibberellin crystal powder has good stability, is easy to transport, and has a long shelf life. However, it is necessary to dissolve it with a small amount of alcohol or white wine before use, and then dilute it with water according to the required concentration. However, improper addition of water will easily recrystallize, which will affect the efficacy and bring inconvenience to practical applications.

Gibberellin EC  

Gibberellin EC is a brown transparent liquid prepared from the extracted gibberellin mother liquor, solvent, and emulsifier. The commonly used solvent is alcohol and the emulsifier is castor oil polyoxyethylene ether. Gibberellin EC has a long production history, mature processing technology, high efficacy, convenient application, and stable properties, so it has large output and a wide range of applications.

However, the organic solvent in the emulsifiable concentrate formulation has a stimulating effect on the young fruit, can increase the skin pores of the fruit surface, reduce the smoothness of the fruit surface, and increase the penetration of pesticides into animals, plants, and humans. If used improperly, it is easy to cause phytotoxicity.

Gibberellin SP

The gibberellic acid soluble powder is prepared by baking, pulverizing, and mixing gibberellic acid crystal powder and other auxiliary materials. The advantages of soluble powder are uniform fineness, good fluidity, easy to measure, dissolve quickly in water, and the active ingredients are evenly dispersed in water in a molecular state.

Compared with other dosage forms, it can give full play to its efficacy; because the dosage form does not contain organic solvents, it will not cause phytotoxicity and environmental pollution due to solvents; it has good storage stability, lower production costs, and is safe to use. Therefore, gibberellic acid soluble powder has been widely developed in recent years.

Gibberellin TB

Tablets are a common basic dosage form in medicine, and their application in pesticides is not universal. Gibberellin tablets are made by compressing granules obtained by spraying a certain proportion of gibberellin and other fillers with alcohol.

It overcomes the shortcomings of powders and liquids, and can be directly put into water to dissolve, dissolve thoroughly, without dust pollution, and reduce environmental pollution; the dosage is accurate, no need to weigh when used, and the operation is convenient;

The active ingredients and the physical and chemical properties of the product are easy to maintain stability and extend the shelf life. Gibberellin tablets are currently mainly used for export.

Emulsifiable concentrates(EC) and crystalline powders(TC) have mature processing technology, high efficacy, convenient application, stable properties, etc. Therefore, gibberellic acid emulsifiable concentrates and crystalline powders are still the current mainstream formulations, occupying a considerable proportion.

Soluble powders(SP) and tablets(TB) have the advantages of being soluble in water, free of organic solvents, easy to measure, convenient and safe to operate, etc. They have developed rapidly in recent years and have gradually become the mainstream formulations.
