  • Plant growth regulator compositions
    Patent number: 6288009
    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.
    Type: Grant
    Filed: April 10, 1998
    Date of Patent: September 11, 2001

  • Controlled release fertilizer
    Patent number: 4042366
    Abstract: A controlled release particulate fertilizer composition containing nitrogen in a form which is slowly released and a water soluble solid additive, such as a phosphorus or potassium nutrient salt, in a form which is quickly released comprising a core of a water soluble nitrogen nutrient source, a coating of sulfur surrounding the core, and a coating surrounding the sulfur coating of an inert water-insoluble material such as wax. The inert coating comprises an inner portion of the inert coating alone and an outer portion containing the salt or other water soluble additive.
