Abstract: Herbicidal combination having a synergistic effect as a result of the combination (a) of bromoxynil or one of its derivatives corresponding to the formula ##STR1## R=H, alkylcarbonyl or K, with (2-[[4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-aminosulphonyl]-N,N-dimeth yl-3-pyridinecarboxamide (II)Application to maize crops.

Abstract: The invention relates to synergistic antimicrobial and biocidal compositions comprising 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one and one or more commercial biocides for more effective, and broader control of microorganisms in various industrial systems.

Abstract: A plant growth enhancing composition comprising as an active ingredient a synergistic mixture of (a) gibberellins, (b) the heteroauxin indole-3-acetic acid and the cytokinin 6-(4-hydroxy-3-methyl-2-trans-betenylamino) purine in definite proportions. Application of the composition to the locus of various plants or to the seeds of a plant produces a wide variety of plant growth enhancing responses including, increasing yields; stimulating seed germination and breaking of dormancy; increasing flowering and fruiting; preventing lodging and freeze injury; aiding in the recovery of damaged crops and increasing root proliferation.

Abstract: The present invention discloses a complex suspended herbicide formulation including: a herbicidally active ingredient of thiolcarbamate type which is liquid at common temperature; a solid herbicidally active ingredient which is slightly soluble in the herbicidally active ingredient of thiolcarbamate type at common temperature; a surfactant; and a dry process white carbon; wherein the solid herbicidally active ingredient is dispersed and suspended in the herbicidally active ingredient of thiolcarbamate type in the presence of the surfactant and the dry process white carbon; and wherein the herbicidally active ingredient of thiolcarbamate type is represented by the formula: ##STR1## wherein R.sup.1 is an alkyl group having from 1 to 3 carbon atoms, a phenyl group, or a halogen-substituted phenyl group; R.sup.2 and R.sup.3 are alkyl groups having from 1 to 5 carbon atoms, with the proviso that R.sup.2 and R.sup.3 may form a ring.
