Abstract: Synergistic antimicrobial and biocidal compositions comprising 2-n-octyl-4-isothizolin-3-one and one or more known biocides for more effective, and broader control of miccroorganisms in various industrial systems are disclosed.

Abstract: A method of selectively combating weeds in beet crops which comprises applying to the beet field before or after emergence of the plants a composition comprising(a) 4-amino-3-methyl-6-phenyl-1,2,4-triazin-5-(4H)-one (metamitron) of the formula ##STR1## and (b) at least one 4-amino-1-carbamoyl-5-methyl-1,2,4-(1H)-triazolin-5-one substituted on the amide nitrogen atom, of the formula ##STR2## in which R represents straight-chain or branched C.sub.1 -C.sub.10 -alkyl (which can optionally be substituted by halogen), or represents straight-chain or branched C.sub.3 -C.sub.8 -alkenyl or C.sub.3 -C.sub.8 -alkinyl, or represents C.sub.3 -C.sub.6 -cycloalkyl (which can optionally be substituted by methyl or trifluoromethyl).

Abstract: Synergistic herbicidal imidazolinone compositions, and methods for their use in selective postemergence control of undesirable plant species in the presence of crops; particularly for the selective control of undesirable plant species of the genera: Ipomoea, Sorghum and Euphorbia, in the presence of leguminous crops, by the postemergence application to the foliage of said plants of a novel synergistic combination of an imidazolinyl nicotinic acid, ester or salt with (1) a different imidazolinyl nicotinic acid, ester or salt, (2) an imidazolinyl-3-quinolinecarboxylic acid, ester or salt, or (3) an N-(heterocyclicaminocarbonyl)arylsulfonamide.

Abstract: A herbicidal composition comprising at least one oxazolidinedione derivative expressed by the following formula: ##STR1## (wherein R.sup.1, R.sup.2 and R.sup.3 independently denote hydrogen atoms, halogen atoms, nitro groups, alkyl groups, alkoxy groups, alkenyloxy groups, alkynyloxy groups or cycloalkyloxy groups; R.sup.4 and R.sup.5 independently denote hydrogen atoms, alkyl groups or aryl groups or may be combined with each other to form a polymethylene chain; and said alkyl groups, alkoxy groups, alkenyloxy groups, alkynyloxy groups, cycloalkyloxy groups and aryl groups may be substituted); and at least one organic phosphorus herbicide, as active ingredients.

Abstract: Substituted tetrazolinones exhibit usefulness as herbicides and plant growth regulators.

Abstract: The present invention provides fine granular compositions of pendimethalin which are non-dusting and non-staining.

Abstract: There is disclosed a herbicide composition in which a postemergent herbicide is activated by the inclusion of a silicone glycol adjuvant consisting essentially of (i) a silicone glycol having an average of 4 or 5 ethylene oxide units in its glycol chain and (ii) a silicone glycol dispersant compound for component (i). The composition provides enhanced phytotoxicity in the control of weeds, particularly velvetleaf plants, and shows an improved degree of rainfastness relative to prior art compositions.

Abstract: This invention relates to a composition comprising a mixture of herbicidal compounds and a method for controlling the growth of undesired vegetation in upland cereal and rice crops by applying to the crop after transplantation or emergence an effective amount of certain sulfonylurea herbicides, alone or the above composition comprising a mixture of herbicidal compounds.

Abstract: Compounds of the formula ##STR1## wherein R.sup.60 is halogen, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, cyano, nitro, S(O).sub.n R wherein R is C.sub.1 -C.sub.4 alkyl and n is the integer 0, 1 or 2; and R.sup.61 through R.sup.66 are hydrogen or certain substituents, their salts, herbicidal compositions containing the compound or salts and the herbicidal use thereof.

Abstract: There is disclosed a herbicidal composition in which a foliar-applied herbicide is activated by the inclusion of a silicone glycol-silicone alkane terpolymer adjuvant. The composition provides enhanced phytotoxicity in the control of narrowleaf weeds, particularly Barnyardgrass, Quackgrass and Johnsongrass, and often also shows an improved degree of rainfastness relative to similar herbicidal compositions employing prior art silicone glycol adjuvants.
