Abstract: Antibiotic A-32256 which is produced by submerged, aerobic fermentation of a Streptomyces sp. NRRL 12067. The antibiotic has shown antibacterial activity against Staphylococcus and Streptococcus and various anaerobic species. In addition, the antibiotic has shown antitrichomonas activity in vitro, as well as activity for improving ruminant feed efficency and as a mosquito larvacide.

Abstract: Antibiotic A-32724 complex, comprising microbiologically-active, related factors A, B and C, is produced by submerged, aerobic fermentation of a strain of Chaetomella raphigera Swift NRRL 12331. The A-32724 antibiotics are closely related antibiotics. The individual A-32724 factors are separated by chromatography. In addition to their antibacterial activity, the A-32724 factors inhibit certain enzymes and exhibit antihypertensive properties.

Abstract: This invention relates to a novel substituted thiadiazole, identified as 1-[5-(2-chloro-1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-1,3-dimethylurea, to its use in a novel method for the control of unwanted vegetation, and to a novel herbicidal composition employing the substituted thiadiazole as the herbicidally-active ingredient.

Abstract: Antibiotic A-39183 complex, comprising microbiologically active, related factors A, B, C, D, and E, is produced by submerged, aerobic fermentation of a new microorganism Streptomyces sp., NRRL 12049. The A-39183 antibiotics are closely related antibiotics. The individual A-39183 factors are separated by chromatography. The A-39183 factors are antibacterial agents which have activity against Staphylococcus and Streptococcus species that are penicillin resistant. The A-39183 factors are also active against both gram-positive and gram-negative anaerobic bacteria, and are ionophores.

Abstract: It has been discovered that fungal foliar phytopathogens may be controlled by the use of a broad class of 2,6-dinitroanilines. The fungicidally-effective compounds may bear a broad range of substituent groups on the anilino nitrogen and in the 3- and 4-positions of the benzene ring.

Abstract: 3-Amino-5-(t-butyl)isoxazole, in optimum yield, is prepared in a stepwise manner by reacting a lower alkyl pivalate and acetonitrile in the presence of a base to yield pivalyl acetonitrile, which in turn is allowed to react with hydroxylamine under controlled conditions of pH to yield the desired compound. The compound is a useful intermediate for the preparation of isoxazole derivatives having utility as herbicides.

Abstract: Preparation of substituted 2-aminopyrazines by reaction of an .alpha.-chloro or .alpha.-bromo oxime with an aminoacetonitrile in the presence of an acid-uptake agent, followed by separation of the intermediate novel hydroxyimino-substituted aminoacetonitrile, and cyclization thereof with acid.
