Abstract: The present invention relates to an herbicide composition, which adds bismuth gelatinzer to a bipyridylium diquaternary salt. Bismuth gelatinzer will form a protecting membrane of a colloidal or dispersed object on the surface of stomach tissue; it is capable of lowering the absorption of bipyridylium diquaternary compound to gastrointestinal tracks then reducing the oral toxicity of bipyridylium diquaternary herbicide.

Abstract: The invention discloses a dried glyphosate granule herbicide composition, comprising 50˜950 g/kg glyphosate, 5˜950 g/kg non-inorganic salt extender, and 0.5˜150 g/kg organo-silicon surfactant. The herbicide according to the present invention uses glyphosate as the active ingredient without turning it into salt derivatives, hence reducing the cost of preparation. The present invention also provides a method for preparing the glyphosate herbicide disclosed.

Abstract: A multi-layer wood pest barrier having a prolonged lifetime that can be as long as the life of a building or structure to be protected. The lifetime protection is achieved by binding at least one pesticide within a continuous or discontinuous polymer matrix layer thereby substantially reducing release of the pesticide from the matrix. The release rate of the pesticide from the matrix can be controlled by the use of a carrier such as carbon black. The release of the pesticide from the barrier can be further controlled by inclusion of additional layers which can make the barrier substantially non-releasing.

Abstract: Noneffervescent pesticidal tablets containing from about 0.1 to about 30 weight percent of a pesticide, from about 0.5 to about 50 weight percent microcrystalline cellulose, from about 5 to about 50 weight percent urea, and from about 0.1 to about 10 weight percent of one or more organic carboxylic acids. The tablets may be packaged in water-soluble film.

Abstract: This invention comprises a granular pesticidal composition having improved attrition resistance comprising from about 10 to about 20% by weight of a pesticide, a glycol or polyvinyl alcohol, the remainder comprising montmorillonite or kaolin clay granules.

Abstract: Herbicidal compositions contain N-phosphonomethyglycine and alkyl phenol polyoxyalkylene surfactant which contains from about 50 to about 90 weight percent of alkyl phenol polyoxyethylene carboxylic acid.

Abstract: Aryl sulfonylureas as new compositions and included in a two-part herbicide system comprising at least one or more thiolcarbamate, thiolcarbamate sulfoxide or haloacetanilide herbicide, and as the second part a non-phytotoxic antidotally effective amount of aryl sulfonylurea as an antidote therefor of the formula ##STR1## in which X is oxygen or sulfur; n is an integer; R is lower alkyl, lower alkoxy, lower alkylthio, halogen, trifluoromethyl, cyano, nitro, lower alkyl sulfonyl;R.sup.4 is hydrogen, lower alkyl, lower alkoxyalkyl, phenyl and chlorophenyl;R.sup.2 is hydrogen, lower alkyl, alkoxyalkyl and phenyl;R.sup.1 is lower alkyl, alkenyl, alkynyl, haloalkyl, alkoxyalkyl, 1-phenylpropenyl, benzyl, chlorobenzyl, haloalkenyl, phenyl and alkyl substituted phenyl; andAR is phenyl, benzyl, naphthyl, pyridyl or styryl; and the inorganic base salts sodium, potassium, ammonium and other inorganic salts; and organic base salts thereof.
