bulletIndications & Usage

The broad-spectrum growth regulator is used for the increase of fruit productivity and the formation of coreless fruits. It promotes the growth of the stems and foliar by supplying nutrients for plants.As a seed protection promoter it can outskirt the inactivation of seed,
prolong the growth period and keep the fruits fresh. When used for the preparation of multi-breeding rice seed, it has positive effects to increase the number and quality of rice-heads.

Gibberellic Acid-3 (GA-3) is a naturally occurring plant growth regulator that may cause a variety of effects, including the stimulation of seed germination in some cases.GA-3 occurs naturally in the seeds of many species and is produced commercially by growing Gibberella fujikuroi fungus cultures in vats, then extracting and purifying the GA-3.Presoaking seeds in GA-3 solution will in many cases cause the rapid germination of many types of highly dormant seeds which would otherwise need cold treatment, after-ripening, aging, or other prolonged pre-treatments.

Gibberellins are used in agriculture for various purposes. GA-3 is sprayed on seedless grapes to increase grape size and yield, and is used on navel oranges, lemons, blueberries, sweet and tart cherries, artichokes and other crops to decrease or increase fruit set, delay rind aging, etc. These effects are highly dependent on concentration and stage of plant growth.

bulletCautions

1. It is readily degradable in basic substances and un-degradable under dry conditions. Its aqueous solution will become ineffective at 5 degree C.
2. The pure product has low water solubility. Dissolve with a little ethanol before use.
3. The GA3-treated cottonseed should not be kept for further sowing.
4. It should be kept at low temperature and at a dry place and prevented from strong light irritation and constant heating.

bulletPacking:

bulletStorage
Kept in a tight-closed container, protected from light and stored  in a dry place.
bulletShelf Life
