Pesticides Such As Tebuconazole, Gibberellic Acid And Flonicamid Will Be Extended in Validity Period

Agrochemical.com Chinese website reported: Recently, based on the PPP regulations for plant protection products (REGULATION (EC) No 1107/2009), the European Union has extended 28 regulations for gibberellic acid, flonicamid, tebuconazole, and chlorpyrazosulfuron-methyl. The expiration date of the active substance.

Among these substances, gibberellic acid has always been a popular substance that has received widespread attention.

The Importance of Gibberellic Acid

Gibberellic acid (Gibberellic acid, GA3) belongs to the gibberellin class of plant growth regulators, and is a ubiquitous endogenous hormone in plants.

In 1935, gibberellic acid was successfully purified from Gibberella for the first time, and then Abbott Laboratories in the United States, ICI in the United Kingdom and Kyowa Fermentation in Japan successively put into production.

Gibberellic acid is an important endogenous hormone that promotes plant growth and development. Artificially produced gibberellic acid is mainly absorbed by leaves, flowers, seeds, twigs or fruits, and then transported to the site of action in the plant body. Gibberellic acid can play many physiological roles, such as:

• Accelerate the growth of plant fruit and promote fruit setting;

• Break seed dormancy and promote early germination;

• Accelerates the elongation and growth of stems and promotes bolting of plants;

• Enlarging the leaf area and activating the cambium;

• Inhibit maturation and senescence, hinder lateral bud dormancy and tuber formation, etc.

In addition, gibberellic acid is currently the most widely used regulator in my country, whether it is rice, wheat, corn, potatoes and other field crops, or fruits and vegetables such as grapes, tomatoes, cucumbers, cherries, or flowers such as rhododendron and magnolia, gibberellic acid Can play a good regulatory role.

The latest expiry date of 28 active substances such as gibberellic acid

At present, gibberellic acid has been registered in China, the United States, the European Union, Brazil and other countries and regions. As of July 2023, gibberellic acid has a total of 22 technical registrations and 221 preparation registrations in China.

Since the re-evaluation work could not be completed before the original validity period, the EU announced to extend the validity period of gibberellic acid to July 15, 2025.

The notification on the extension of the validity period of active substances in the EU also includes popular active substances such as flonicamid, tebuconazole, and chlorpyrazosulfuron-methyl. The specific information is as follows:
