Abstract

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.
