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) For use as a seed treatment on both semi-dwarf and tall rice varieties to promote germination, emergence and final stand densities when planted at greater depths where soil moisture levels are more adequate for germination:

Apply only to rice seed intended for drill seeded or dry broadcast systems. Do not apply to rice used in a 24-hour presoak prior to broadcast or to water used for the presoak. Do not use more than 2.1 grams a.i. per 100 pounds of seed. DO NOT USE TREATED SEED FOR FOOD, FEED, OR OIL PURPOSES.

Use 0.5 to 2.1 grams a.i. in 8 to 20 oz. water per 100 pounds of rice seed. GibGro can be applied to dry seed with standard mist-treating equipment. Best results are obtained using a higher treatment volume (12 to 20 fl. oz. per 100 pounds of seed) to ensure the seed is completely and uniformly covered with GibGro. Fill the seed treatment tank with water to one-half the final tank mix volume. Add the required amount of GibGro, mixing thoroughly while adding water and other seed treatment products to the desired final volume.

An approved dye must be added to distinguish GibGro treated seed and prevent inadvertent use for food, feed or oil purposes. Seed commercially treated with this product must be labeled in accordance with all applicable requirements of the federal and state seed laws. GibGro is compatible with most commonly used fungicide seed treatments such as VITAVAX and DITHANE, standard dyes and sticker-binding agents. When preparing tank mixes, the user should ensure adequate physical compatibility and mixing characteristics.
