Abstract: A method of regulating the growth of submerged and floating aquatic weeds which comprises adding a 2- or 4-substituted pyridinemethane or pyridinemethanol to a body of water containing the submerged and floating aquatic weeds to be regulated, in quantities sufficient to regulate the growth of the submerged and floating aquatic weeds therein. The disclosure also relates to novel compositions for carrying out the method.

Abstract: A method of regulating the growth of submerged and floating aquatic weeds which comprises adding a fluoroalkoxyphenyl-substituted 3-pyridinemethanol to a body of water containing the submerged and floating aquatic weeds to be regulated, in quantities sufficient to regulate the growth of the said submerged and floating aquatic weeds. The disclosure also relates to novel compositions for carrying out the method.

Abstract: Novel substituted thiadiazolotriazinediones, active as herbicides, antimicrobial agents, antiviral agents, and a method for their preparation, together with herbicidal methods and compositions employing said novel compounds.

Abstract: Fungi which attack agricultural crops and ornamental plants, are controlled by applying to the locus of the fungi .alpha.,.alpha.-dialkyl-substituted 3-pyridinemethanols or nonphytotoxic acid addition salts thereof.

Abstract: There are disclosed novel 3-[(5-nitro-2-imidazolyl)pyrazol-5-yl]oxamic acid derivatives and salts thereof, exhibiting utility as antibacterial, antiprotozoal, and antifungal agents, making the compounds useful particularly in veterinary medicine, especially in controlling bacterial and protozoal infections of cattle, swine, and poultry.

Abstract: There is disclosed a class of fluoroalkoxyphenyl-substituted nitrogen-containing heterocycles which are useful as herbicides, plant fungicides, and plant growth regulators. Internodal elongation of plants is inhibited by treatment with compounds of this invention.

Abstract: There are disclosed novel 3-(5-nitroimidazol-2-yl)-pyrazolo[3,4-d]pyrimidine compounds exhibiting utility as antibacterial and antiprotozoal agents.

Abstract: A method for moderating the effects of viral infections in animals by administration thereto of a polyether ionophorous antibiotic selected from the group consisting of monensin, A-28086, A28695, A28695A, A28695B, nigericin, and carbomonensin.

Abstract: Novel 1,3,4-thiadiazol-2-ylureas characterized by an hetero-ring sulfamoyl group at the 5-position, and by small alkyl or alkoxy groups on the urea nitrogens. The hetero-ring groups are 5- and 6-membered rings containing an oxygen, sulfur, or nitrogen atom, and may optionally be linked to the sulfamoyl nitrogen by a methylene group. The novel compounds are effective pre- and postemergence herbicides.

Abstract: A method of controlling aquatic weeds which comprises adding to a body of water containing the aquatic weeds a substituted 1-thiadiazolyl-3-arylurea in sufficient quantity to kill the weeds.

Abstract: There are disclosed novel 3-(5-nitro-2-imidazolyl)-pyrazoles exhibiting utility as antibacterial, antiprotozoal, and antifungal agents, making the compounds useful particularly in veterinary medicine, especially in controlling bacterial and protozoal infections of cattle, swine, and poultry. The compounds are also active as growth promoters in chickens.

Abstract: There is disclosed a method of controlling unwanted vegetation in fallow wheatland by the application of a substituted thiadiazol-2-ylurea following the harvesting of the wheat crop.

Abstract: There is disclosed a class of fluoroalkoxyphenyl-substituted nitrogen-containing heterocycles which are useful as herbicides, plant fungicides, and plant growth regulators. Internodal elongation of plants is inhibited by treatment with compounds of this invention.

Abstract: The process for brominating pyrimidine which comprises reacting bromine at an elevated temperature with the hydrogen halide addition salt of pyrimidine in an organic solvent substantially inert to the action of bromine under the conditions of the process. The process is also shown to be applicable to other nitrogen-containing heterocycles.

Abstract: There are disclosed novel 3-(5-nitro-2-imidazolyl)-pyrazoles exhibiting utility as antibacterial, antiprotozoal, and antifungal agents, making the compounds useful particularly in veterinary medicine, especially in controlling bacterial and protozoal infections of poultry and swine. The compounds are also active as growth promoters in chickens.

Abstract: An improved process for removal of halogen from the pyrimidine ring only of a compound of the formula ##SPC1##WhereinAt least one of X is chlorine or bromine, the remainder hydrogen; .[.or lower alkyl.].Q is chlorine or fluorine; andN is an integer from 1 to 5.The dehalogenation process yields an .alpha.-halophenyl-.alpha.-phenyl-5-pyrinidylmethane of 95 percent or higher purity, which compound is useful as an intermediate in the preparation of the corresponding .alpha.-halophenyl-.alpha.-phenyl-5-pyrinidylmethanol, useful as an agricultural fungicide.

Abstract: There is disclosed a class of fluoroalkoxyphenylsubstituted nitrogen-containing heterocycles which are useful as herbicides, plant fungicides, and plant growth regulators. Internodal elongation of plants is inhibited by treatment with compounds of this invention.
