Abstract: The present invention provides a composition for inhibiting phase separation and the resulting non-uniform distribution of an active ingredient in low viscosity, water-based pesticide suspensions. In accordance with this invention, the composition comprises from about 0.003% to about 50% by weight of a pesticide, from about 0.5% to about 10% by weight of a wetting agent; from about 0.0% to about 0.8% by weight of a thickener; from about 0.1% to about 0.5% of an antimicrobial agent; from about 5% to about 20% of an anti-freeze; from about 1% to about 8% of a hydrophobic fumed silica; and from about 40% to about 95% of water. In an embodiment of the invention, the hydrophobic fumed silica results from a hydrophilic silica which is treated with dimethyldichlorosilane.

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.

Abstract: Compositions and methods are disclosed for sanitizing aqueous media, which combine a chlorine-source composition and a glycoluril-source composition. The compositions are added together or separately, continuously or periodically, and by any of a variety of methods. The glycoluril compound stabilizes the chlorine and prolongs its useful life as a microbicidal agent.

Abstract: 4-substituted pyridyl-3-carbinols of the formula ##STR1## wherein R is hydrogen, or an acyl, alkyl or carbamyl group exhibit desirable preemergent and postemergent herbicidal activity. Also disclosed are herbicidal compositions comprising such compounds and methods of controlling undesirable vegetation employing such compounds. The compounds wherein AR is hydroxyl serve as useful intermediates for the production of the alpha-benzyl substituted compounds as well as exhibiting herbicidal activity.

Abstract: Disclosed is a chemically stabilized herbicidal oil-based suspension, comprising N-[(4,6-dimethoxypyrimidin-2-yl) aminocarbonyl-3-dimethylaminocarbonyl-2-pyridinesulfonamide (nicosufluron) and/or its salt as an effective herbicidal component, urea, a vegetable oil and/or mineral oil, a surfactant and, as desired, an additional herbicidal component, a thickener, a solvent and other adjuvants. The present invention is characterized in that urea is added to a herbicidal oil-based suspension to suppress decomposition of the effective herbicidal component and to provide a chemically stabilized herbicidal oil-based suspension.
