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.
To improve fruit set on Highbush varieties such as Coville, Jersey, Stanley, Earliblue, Weymouth, Walcott, Berkeley, Blueray, Bluecrop, 1316A and Concord: Make two applications of 40 grams a.i. per acre in 40 to 100 gallons of water. Apply the first spray at full bloom (when over 75% of all flowers are fully open), followed by a second spray 10 to 14 days later. For Weymouth, application can be delayed up to two weeks after full bloom to affect sizing of shot berries.
To improve fruit set on Rabbiteye varieties such as Aliceblue, Beckyblue, Bonita, Brightwell, Climax, Delite, Tiftblue and Woodward: Beginning at bloom Stage 5 (majority of flowers are elongated but not open), apply two to four applications of 20 to 40 grams a.i. per acre in 40 to 100 gallons of water per application. Make applications 10 to 14 days apart.
