    Abstract: The present invention relates to the use of a pesticidal mixture PM comprising at least one compound of formula I as defined in the specification, an insecticide II and a fungicide III for protecting plants selected from wheat, maize, barley, oat, rye, rice, soybean, cotton, sugarbeet, rapeseed, and potato, the plant propagation material thereof, or soil or water, in which the plants are growing, against the attack or infestation by invertebrate pests and/or phytopathogenic harmful fungi. Furthermore, the present invention relates to a seed treatment composition comprising the pesticidal mixture PM and to seeds comprising the pesticidal mixture PM or the seed treatment composition thereof. Moreover, the present invention relates to a method for controlling invertebrate pests and/or phytopathogenic harmful fungi on plants selected from wheat, maize, barley, oat, rye, rice, soybean, cotton, sugarbeet, rapeseed, and potato comprising contacting the plant or the plant propagation material; the pest or its food supply, habitat or breeding ground; and/or the fungi or their habitat, with an effective amount of the pesticidal mixture PM or the seed treatment composition thereof. In a further aspect, the present invention relates to binary mixtures of a compound of formula I and tioxazafen, tetraniliprole, broflanilide, cyhalodiamide, fluazaindolizine, and fluxametamide, resp.
