  • Patent number: 9801380
    Abstract: The invention relates to low volatile organic chemical gibberellic acid (“GA3”), gibberellin 4 (“GA4”), gibberellin 4/7 (“GA4/7”), or combinations thereof formulations and methods of their use. Specifically, formulations of the present invention are directed toward agricultural formulations including from about 1 to about 10% of at least one gibberellin selected from the group consisting of GA3, GA4, and GA4/7, from about 85 to about 99% polyethylene glycol with a molecular weight from about 190 to about 420, and from about 0.1 to about 5% of a non-ionic or anionic surfactant, wherein the formulation does not include isopropyl alcohol, and wherein the percentages are percent by weight of the formulation.
