  • Aqueous suspension concentrate compositions of pendimethalin
    Patent number: 5624884
    Abstract: The present invention relates to novel stable aqueous suspension concentrate or aqueous flowable compositions of the low-melting dinitroaniline pesticide, pendimethalin, in combination with secondary herbicide(s) melting at temperatures greater than 70.degree. C. or herbicides which are water soluble. Uniquely, pendimethalin may be present in the compositions of the invention in a ratio of orange crystal form to yellow crystal form of 4:96, up to totally orange crystal form. Additionally are provided methods for preparing the compositions containing pendimethalin alone or in combination with the secondary herbicides.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: April 29, 1997
    Assignee: American Cyanamid Company
    Inventors: Leonard J. Morgan, Mark Bell
