Composition comprising biological control agents

A seed treated with a composition comprising a biological control agent (I) selected from the group consisting of

• Paecilomyces lilacinus strain 251 (AGAL No. 89/030550) and Coniothyrium minitans CON/M/91-08 (DSM 9660)
• and/or a mutant of these strains having all the identifying characteristics of the respective strain, and/or at least one metabolite produced by the respective strain that exhibits activity against nematodes, insects and/or phytopathogens,
• and at least one further biological control agent (II) which is selected from the group consisting of fungi and yeasts,
• in a synergistically effective amount.

Kit of parts comprising at least one biological control agent (I) selected from the group consisting of

• Paecilomyces lilacinus strain 251 (AGAL No. 89/030550) and Coniothyrium minitans CON/M/91-08 (DSM 9660)
• and/or a mutant of these strains having all the identifying characteristics of the respective strain, and/or at least one metabolite produced by the respective strain that exhibits activity against nematodes, insects and/or phytopathogens,
• and at least one further biological control agent (II) which is selected from the group consisting of fungi and yeasts,
• in a synergistically effective amount in a spatially separated arrangement.

A method for reducing overall damage of plants and plant parts as well as losses in harvested fruits or vegetables caused by insects, mites, nematodes and/or phytopathogens comprising the step of simultaneously or sequentially applying at least one biological control agent (I) selected from the group consisting of

• Paecilomyces lilacinus strain 251 (AGAL No. 89/030550) and Coniothyrium minitans CON/M/91-08 (DSM 9660)
• and/or a mutant of these strains having all the identifying characteristics of the respective strain, and/or at least one metabolite produced by the respective strain that exhibits activity against nematodes, insects and/or phytopathogens,
• and at least one further biological control agent (II) which is selected from the group consisting of fungi and yeasts,
• and optionally at least one fungicide and/or insecticide on the plant, plant parts, harvested fruits, vegetables and/or plant's locus of growth in a synergistically effective amount.
