Application Instructions:
ProGibb 4% Plant Growth Regulator Solution (Hereafter referred to as ProGibb 4%) contains gibberellic acid, which is an extremely potent plant growth regulator; when applying plant growth regulators, deviations from the label directions in the rates, timings, water volumes, or the adoption of untested spray mixes, results in undesirable effects. Always consult the Valent agricultural specialist in your area for the spray regimen best suited to your conditions.

Do not apply to plants under pest, nutritional, or water stress. When a range of rates is indicated, use the concentration and spray volume directed locally by the Valent agricultural specialist.
For optimum effectiveness, thorough spray coverage must be achieved; all parts of the plant or crop must receive the spray or desired results will not occur. Prepare solution concentrations by mixing the required amount of product with water in a clean, empty spray tank. Dispose of any unused spray material at the end of each day following local, state or federal law.
For most efficacious results, use water with a pH of 4.0 - 8.5. Use a buffer for water with pH above or below this range.
ProGibb 4% applications made under slow drying conditions (cool to warm temperatures, medium to high relative humidity, and no wind) will increase absorption by the plant, thus optimizing effectiveness. Night time applications are encouraged when day time conditions are not conducive to slow drying conditions.
Rain fastness: Re-apply ProGibb 4% if significant rain occurs within 2 hours of application.
Compatibility: When considering tank mixing with other products, use the following compatibility jar test before mixing a whole tank. Start with a clear glass or plastic quart jar. Add water from the same water source that will be used for the larger tank mix. Add the pesticides in correct proportions. Mix thoroughly and let stand for a minimum 15 minutes. Heat, separation, gelling are all signs of incompatibility.
Before using any mixes that pass the jar tests for compatibility, it is imperative to test the mixture on a designated area as it may result either in phytotoxicity or ineffectiveness. For further information, consult your local Valent representative.
Do not apply using ULV application methods. For aerial applications spray volumes must be greater than 2 gallons per acre (10 gallons per acre for tree crops). No preharvest interval is required for this product.
