Abstract: The present invention relates to novel nitrification inhibitors of formula I. Moreover, the invention relates to the use of these novel nitrification inhibitors for reducing nitrification, as well as agrochemical mixtures and compositions comprising the nitrification inhibitors. Further encompassed by the present invention are methods for reducing nitrification comprising the treatment of plants, soil and/or loci with said nitrification inhibitors, and methods for treating a fertilizer or a composition by applying said nitrification inhibitor.

Abstract: The present invention relates to an agrochemical mixture for reducing nitrous oxide and/or ammonia emission from soils, comprising: 1) a composition (component A) comprising N-n-butylthiophosphoric triamide (NBTPT) and/or N-n-propylthiophosphoric triamide (NPTPT); and 2) at least one strobilurin (component B) selected from the group consisting of pyraclostrobin, azoxystrobin, dimoxystrobin, enestroburin, fluoxastrobin, kresoxim-methyl, metominostrobin, orysastrobin, picoxystrobin, trifloxystrobin, pyrametostrobin, pyraoxystrobin, coumoxystrobin, coumethoxystrobin, fenaminostrobin (=diclofenoxystrobin), flufenoxystrobin, 2-(2-(6-(3-chloro-2-methyl-phenoxy)-5-fluoro-pyrimidin-4-yloxy)-phenyl)-2-methoxyimino-N-methyl-acetamide, 3-methoxy-2-(2-(N-(4-methoxy-phenyl)-cyclopropane-carboximidoylsulfanylmethyl)-phenyl)-acrylic acid methyl ester, methyl (2-chloro-5-[(1-(3-methylbenzyloxyimino)ethyl]benzyl)carbamate and 2-(2-(3-(2,6-dichlorophenyl)-1-methyl-allylideneaminooxymethyl)-phenyl)-2-methoxyimino-N methyl-aceta

Abstract: The invention relates to preparations with improved urease-inhibitory effect which comprise at least two different (thio)phosphoric triamides and to urea-comprising fertilizers which comprise these preparations. The invention furthermore relates to a method of preparing these preparations, to the use of these preparations in the fertilization with urea-comprising fertilizers, and to the use of urea-comprising fertilizers which comprise these preparations in agriculture or in horticulture.
