Cherries treated with gibberellic acid (GA) plant growth regulator ProGibb


ProGibb® is a gibberellic acid (GA3) plant growth regulator product. GA3 is found naturally in virtually all plant species. It is a highly effective growth promoter – increasing size and quality of fruits, vegetables, and other crops, essential for optimum growth and development. GA3 also plays a role in the regulation of other plant processes such as flowering, seed germination, dormancy, and senescence. ProGibb is used in many crops to improve crop quality and value.

Registered in 1962, ProGibb is the most widely used GA3 product in the world. Registered crops and uses include:
