  • Substituted N-aroyl N'-phenyl urea compounds
    Patent number: 4468405
    Abstract: Novel N-aroyl N'-phenyl ureas having halogen substituents in the 3- and 5-positions and haloalkyl, haloalkoxy or haloalkylthio in the 4-position of the N'-phenyl are more active and have a broader spectrum of effectiveness than the known benzoylurea insecticides.
    Type: Grant
    Filed: July 26, 1982
    Date of Patent: August 28, 1984
    Assignee: The Dow Chemical Company
    Inventors: Raymond H. Rigterink, Ronald J. Sbragia
  • Simultaneous fungicidal and miticidal protection of plants employing certain tin compounds
    Patent number: 4224338
    Abstract: Method of protecting plants from both fungal organisms and mites in the same treatment in which there is applied to the plant an amount of one or more of selected tricyclopentyl tin and tris(cyclopentylmethyl)tin compounds, which amount is sufficient to provide both antifungal and miticidal protection but is less than a substantially harmful phytotoxic amount. Counter ions in these compounds which are suitable include hydroxy, halo, oxo, thioxo, alkyl- and aryl carboxylate, thiocyanato, diloweralkyldithiocarbamoyl and diethoxyphosphinothioylthio.
