Abstract: Plant growth is regulated, e.g., inhibited or stimulated, by application to the plants or their habitat of effective amounts of at least one 5-azolyl-[a,d]-dibenzocycloheptene compound of the formula ##STR1## WHEREIN X is a --CH.dbd.CH-- or --CH.sub.2 --CH.sub.

Abstract: .alpha.-Oxothiodimethylamide compounds such as tert.-butyl-glyoxyl acid thiodimethylamide are prepared by reacting an .alpha.-chloroketone of the formula ##STR1## in which X is hydrogen or chlorine andR.sup.1 is alkyl or arylWith sulfur and dimethylamine in water at a temperature between 50.degree. and 90.degree. to produce the corresponding .alpha.-oxothiodimethylamide of the formula ##STR2## wherein R.sup.1 is identified above.

Abstract: Photographic images are produced by imagewise exposure, development and stabilization in which development is carried out in the presence of an .alpha.,.alpha.'-[2,5-dimercapto-1,2,4-triazolyl-4-imino] -p-xylene compound which improves the stability of the silver image in extreme climatic conditions.

Abstract: Plant growth regulant compositions containing as an active ingredient 2-cyano-bicyclo[2,2,1]heptane exhibit strong growth regulating activity, e.g., to induce shortening and thickening of the stem in cereals and other crop plants, increasing the yields of certain crops, or the setting of fruit.

Abstract: Azomethine compounds of 4-amino-5-H-1,2,4-triazin-5-ones of the formula ##SPC1##Wherein:R.sup.1 is alkyl, cycloalkyl or phenyl;R.sup.2 is hydrogen or alkyl;R.sup.3 is alkyl, alkoxy, cycloalkyl, cycloalkenyl, aralkyl, aryl or heteroaryl, or dialkylamino;R.sup.2 and R.sup.3 jointly can be an alkylene bridge, optionally interrupted by a hetero atom; andR.sup.4 is alkyl or optionally substituted phenyl,Are markedly effective herbicides, particularly selective herbicides for weeds growing in oats, wheat, cotton, maize, tomatoe, potatoe, soybean, and especially in beet cultivations.

Abstract: Novel glyoxylic acid hydrazide-2-acylhydrazones of the formula: ##EQU1## in which R.sup.1 is hydrogen or alkyl, andR.sup.2 is alkyl or optionally substituted phenyl and are prepared by reacting the corresponding glyoxylic acid ester 2-acylhydrazone with hydrazine hydrate. The compounds (I) are useful in preparing herbicidally active 4-amino-1,2,4-triazin-5-one compounds.

Abstract: Novel 3,4-dihydro-1,2,4-triazine compounds of the formula ##SPC1##In whichR.sup.1 is alkyl or cycloalkyl;R.sup.2 is methyl, amino, alkylideneamino, methylamino, .beta.-hydroxyethylamino, 2-furylmethylamino, aralkylamino or substituted aralkylamino; and R.sup.3 is alkyl, aryl or substituted aryl;Are prepared by reacting the corresponding 1,2,4-triazin-5-one with sodium borohydride in the presence of a polar solvent at a temperature between -10.degree. and +25.degree.C. The novel compounds are outstandingly effective as herbicides and display particularly selective action.
