Abstract: Plant growth regulating preparations comprising:(a) 0.1-20 wt. % of a 16,17-dihydro gibberellin of formula (Ia) or (Ib);(b) up to 99.9 wt. % of a formulation additive selected from:(b1) the reaction products of triglycerides based on carboxylic acids having 2-30C and ethylene oxide and/or propylene oxide in the presence of a base, and/or(b2) fatty acid alcohol polyethoxylates;(c) up to 50 wt. % of an organic solvent;(d) 0.1-50 wt. % of a formulation auxiliary different from (b1) and (b2);(e) up to 50 wt. % of additional plant growth regulating compounds can be used in agriculture and horticulture to induce the desired effects on, for example, seed germination and seedling growth, rooting, dormancy, juvenility, maturity and senescence, flowering, abscission of leaves, flowers and fruit, fruit set and development, tuber formation, growth of shoot and root, photoassimilation, control of unwanted plants and senescence of whole plants or single organs. The 16,17-dihydroGA's are used to synergize the biological activity of exogenously supplied gibberellins. Particularly in graminaceous species, the compounds synergize the action of exogenous GA's and can, thus, be used to increase the yield of malt and decrease the amount of time required for the malting process, increase the yield of sugar cane and stimulate germination and seedling development in rice, wheat, barley, oats, rye, maize, sorghum, turf grasses and other plant species.
