Abstract: Plant growth regulator (PGR) compositions include a plant growth regulating effective mixture of (A) a N,N-dimethyl piperidinium salt (preferably, mepiquat chloride), (B) a hexitol (preferably, myo-inositol), and optionally (C) a compound which promotes cytokinesis in plant cells (i.e., a cytokinin). The hexitol and cytokinin are most preferably provided collectively in the composition by the presence of an effective amount of coconut milk. Synergistic results in terms of enhanced cotton lint yields are obtained by applying the PGR compositions of this invention to growing cotton plants.

Abstract: The invention is a novel method for the control of the relative stem growth of graminaceous crops, comprising applying to the foliage, stems, roots or seeds of said plants, or to the soil in which said plants are grown, a plant growth regulating amount of a substituted phenylnitramine.

Abstract: There are provided di- tri- and tetrasubstituted N-nitroaniline compounds and inorganic and organic salts thereof which are effective for increasing axillary branching, improving canopy and enhancing flowering of herbaceous ornamental plants and graminaceous crops, leguminous crops, cotton and sunflowers. The salts are also effective as yield enhancing agents and lodging inhibitors for the crops.

Abstract: This invention relates to a method for regulating the growth of crop plants by applying to the foliage, roots, stems, seeds or to soil in which the crop plants are grown, an effective plant growth regulating amount of an imidazolinyl benzamide having the structure: ##STR1## wherein R.sub.1 is alkyl C.sub.1 -C.sub.4 ; R.sub.2 is alkyl C.sub.1 -C.sub.6, cycloalkyl C.sub.3 -C.sub.6, alkenyl C.sub.2 -C.sub.4, phenyl, halophenyl or benzyl; and when R.sub.1 and R.sub.2 are taken together with the carbon to which they are attached they may form cycloalkyl C.sub.3 -C.sub.6 optionally substituted with methyl; R.sub.3 and R.sub.4 each individually represent hydrogen, alkyl C.sub.1 -C.sub.4, alkenyl C.sub.3 -C.sub.5, alkynyl C.sub.3 -C.sub.5, or benzyl; and when R.sub.1 and R.sub.2 represent different substituents, the optical isomers thereof.

Abstract: This invention relates to a method for controlling the relative stem and/or axillary growth of plants by applying to the foliage of the plants, to soil containing seeds of the plants, or to soil in which the plants are growing, a plant-growth regulating amount of an imidazolinyl benzoic acid, ester or salt.
