摘要:
The invention provides novel mixtures of quaternary ammonium salts having plant growth-regulating properties. The salts, as well as other active ingredients used to regulate plant growth, are dissolved in solvents having either formula II(a) or II(b), as depicted below: wherein “R” is Hydrogen or a C1-C16 alkyl, “n” is 0, 1, 2 or 3, “A” is a C1-C6 alkene or a C1-C6 oxyalkylene, “m” is 1, 2, 3, 4 or 5, and “B” is a straight-chain or branched C2-C8 alkylene.
摘要:
The invention provides novel mepiquat plant growth regulator compositions which have improved hygroscopicity and corrosion characteristics. The novel mepiquat plant growth regulator compositions of the invention can be readily prepared from technical mepiquat chlorid inter alia by electrochemical ion exchange processes or by quaternization of N-methylpiperidine with dimethylcarbonate as starting material.

摘要:
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.
