CITRUS - VALENCIA ORANGES - CALIFORNIA AND ARIZONA
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 4LS to be applied.
Use only as directed. The label must 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 4LS with other agricultural compounds is not available, except where specified.
To assure the compatibility of GIBGRO 4LS with other products, pour the products into a small container of water in the correct proportions.
After thorough mixing, let stand for 5 minutes. If the combination remains mixed, or can be remixed readily, the mixture is compatible.
For all citrus, apply in sprays of sufficient water volumes to ensure thorough fruit wetting. Application to trees under stress or to trees of low vigor has the potential to cause severe leaf and/or fruit drop. A slight increase in mature leaf drop may be observed after application. Do not apply in white wash sprays in which lime or other caustic material has produced a high pH in the spray tank. If copper fungicides, insecticides, and/or oils or surfactants are applied within three weeks, either before or after, application of GIBGRO 4LS, significant leaf and fruit drop may occur.
(For California and Arizona use only) To reduce rind creasing and to delay aging and softening of the rind: Apply a single spray in August to October to trees with a target crop of young fruit. Apply 40 to 80 grams a.i. per acre as a concentrate or dilute spray in sufficient water volume to ensure thorough wetting.
NOTE: Do not apply the early spray to groves that will be harvested early as a reduction in grade may result due to the delayed coloring. Slower color development can be expected in the target crop. Increased regreening of mature fruit, if present, may occur. After marketable color is achieved, treatment effects will be reduced the longer treated fruit remain on the tree.
