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


To increase plant height and yield, and overcome stress due to cold weather conditions, or saline soils and to obtain earlier maturity: Apply spray one to four weeks prior to harvest. Lower concentrations are applied at the three to four-week interval. Higher concentrations at the one to two-week interval.

Use in 25 to 50 gallons of water per acre for ground application or 5 to 10 gallons of water per acre for aerial application (except in California).

NOTE: Do not apply earlier than four weeks before harvest as Gibberellic Acid may induce bolting (seed stalk formation). Do not apply by air in California.
