General Information

Do not apply this product through any type of irrigation system.

NOTE: Gibberellic Acid is an extremely potent plant growth regulator. For best results, read all directions for use thoroughly. Consult your local experiment station specialist, distributor, or the Nufarm agricultural specialist in your area for the spray schedule best suited to your conditions.

Discard any unused spray material at the end of each day. Prepare solution concentrations by mixing the required amount of product with water only in a clean, empty spray tank. Refer to individual crop sections and rate conversion tables provided in the labeling for the amount of GibGro to be applied.

Use only as directed. The label should be read thoroughly and understood before making applications.

Effectiveness requires that all parts of plant or crop must receive spray or desired result will not occur, so spray thoroughly. When a range of rates is indicated, use the concentration and spray volume recommended locally.

Data concerning the compatibility of GibGro with other agricultural compounds is not available, except where specified.

Refer to the label regarding tank mix information.

Limitations, Restrictions, and Exceptions


(All states except California)

Applying GibGro to ornamental plants grown for cut flowers will aid in promoting longer stems and increased flower yield. Gibberellic Acid is a potent plant growth regulator and overuse may result in undesirable effects. Assess the effects of GibGro on a small number of plants prior to making large scale applications.

STATICE (Limonium)

To promote earlier flowering and to increase flower yield: Apply as a foliar spray consisting of 10 ml of a 400 to 500 ppm a.i. solution when plants are more than 10 inches in diameter (approximately 90 to 110 days after normal seeding time).

NOTE: Do not exceed specified rates. Do not apply repeated sprays. Accelerated flowering is influenced by extended photoperiod, adequate nutrition and reduced night temperature. Treatment with Gibberellins lessens the requirement for the cold requirement and/or the long photoperiod.

To promote plant growth and longer stems: Apply a 50 to 100 ppm a.i. solution as a foliar spray when plants are 4\" to 8\" tall. Make applications at 2 to 3 week intervals.
