  • Patent number: 5389598
    Abstract: Disclosed are storage-stable aqueous concentrate formulations of pesticides or plant growth modifying agents containing sufficient amounts of an alkoxylated alkylamine surfactant to insure a high degree of pesticidal or plant growth modifying efficacy, wherein irritancy to eyes resulting from the presence of said surfactant is reduced by the presence of an effective amount of a C.sub.6-22 saturated or unsaturated alkyl monocarboxylic or dicarboxylic acid or mixture of such acids.
    Type: Grant
    Filed: December 17, 1993
    Date of Patent: February 14, 1995
    Assignee: Monsanto Company
    Inventors: Howard C. Berk, James W. Kassebaum
  • Patent number: 5317003
    Abstract: A herbicidal composition is provided which is substantially non-irritant to the eyes and which comprises a stable aqueous concentrate solution of one or more agriculturally acceptable salts-of N-phosphonomethylglycine and a surfactant represented by the formula ##STR1## wherein R is an alkyl group having from about 6 to about 14 carbon atoms, R.sup.1 is ethyl, propyl, or a mixture of ethyl and propyl, the sum of n and m is between about 5 and about 50, R.sup.2 is an alkyl group with 1-4 carbon atoms, X is an agriculturally acceptable anion, and the weight ratio of surfactant to N-phosphonomethylglycine (expressed as the acid equivalent) is between about 1:5 and about 5:1.
