It's a well-known fact that the application of gibberellins GA4 and GA7 can increase fruit size and improve fruit finish in apples. However, research has shown that GA4 is more efficient in delivering these benefits than GA7. And, GA7 adversely affects the level of return bloom significantly more than GA4.

In Novagib, Fine Americas employs a unique fermentation process to produce ultra-pure GA4 with insignificant levels of GA7. The result: a highly effective PGR that delivers all the benefits of GA4 without the drawbacks of GA7.
