Mepiquat chloride is formed from the reaction between N-methylpiperidine and chloromethane in an anhydrous liquid solvent selected from the group consisting of acetone, methyl ethyl ketone, toluene, tetrahydrofuran, isopropanol, acetonitrile, N,N-dimethylformamide and methylene chloride in the absence of sodium hydroxide. Mepiquat chloride precipitates as a solid of high purity and is recovered under a substantially moisture-free atmosphere. The solid mepiquat chloride can be sealed into a water soluble pouch or into a water soluble encapsulated solid form (e.g., granule, pellet, or briquette) for convenient handling. The pouch contains powdered mepiquat chloride or the encapsulated solid is merely introduced directly into a spray tank or reservoir for application with low human exposure and no containers in contact with the mepiquat chloride that require disposal. Mepiquat chloride is used as a component of a system for growing a number of commodity plants including cotton. The first component is a plant growth regulator applied. to at least one of: (a) a furrow for cotton plant seeds, (b) to a cotton plant bearing the first true leaves, (c) to a cotton plant at pinhead square, and (d) to a cotton plant at early bloom. The plant growth regulating agents produce higher plant masses with high levels of boll retention. At mid-bloom, mepiquat chloride is applied to retard vegetative growth in favor of fruit (boll) production.
