The invention relates to an inorganic fertilizer which provides both nourishment and protection for plants. Said fertilizer contains at least one nutrient from the group including nitrogen, phosphorus, potassium, magnesium, sulfur or calcium as well as between 0.1 to 200 g/kg fertilizer of a biological preparation for plant protection. The biological preparation protects plants against disease and/or pests and consists of an inert carrier mixed with the conidia of at least one type of filamentous fungus chosen from the group comprising the geni Trichoderma, Beauveria, Metarhizium, Paecilomyces, Tolypocladium or Verticillium, which are contained in quantities of between 0.5 and 1.5 . 10<10> conidia per 1g of biological preparation. The above fertilizer is produced by spraying granules of inorganic fertilizers, which are usually surface-treated and contain at least one of the nutrients listed above, with coating substances which have been diluted with oil and chosen from the group including the amines and advantageously octadecylamine or alkylarylsulfonates. The granules are then coated with a powder to which a biological plant protecting preparation has been admixed. The powder is chosen from a group of substances which include kaolin, talc or finely ground limestone. |
