摘要

mixtures comprising a urease inhibitor (ui) and a nitrification inhibitor, such as 2- (3,4-dimethyl-1h-pyrazol-1-yl) succinic acid (dmpsa) or 3,4-dimethyl pyrazolium glycolate (dmpg ). the present invention relates to mixtures comprising as active components at least one specific nitrification inhibitor (compound i) and at least one urease inhibitor (compound ii); a method to improve the nitrification inhibiting effect, or to increase the health of a plant using mixtures of at least one compound i and at least one compound ii; the use of mixtures comprising compounds i and compounds ii to increase the health of a plant; the agrochemical composition comprising these mixtures; and a plant propagation material, comprising these mixtures or this agrochemical composition.
