Composition comprising a biological control agent and an insecticide

The present invention relates to a composition comprising at least one biological control agent selected from the group consisting of Paecilomyces lilacinus strain 251 (AGAL No. 89/030550), Trichoderma atroviride SC1 (CBS No. 122089), 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 a metabolite produced by the respective strain that exhibits activity against nematodes, insects and/or phytopathogens, and at least one insecticide (I) selected from the group consisting of and at least one insecticide (I) selected from the group consisting of juvenile hormone mimics, miscellaneous non-specific (multi-site) inhibitors, selective homopteran feeding blockers, mite growth inhibitors, microbial disruptors of insect midgut membranes, inhibitors of mitochondrial ATP synthase, uncouplers of oxidative phoshorylation via disruption of the proton gradient, inhibitors of chitin biosynthesis (type 0), inhibitors of chitin biosynthesis (type 1), moulting disruptors, ecdysone receptor agonists, octopamine receptor agonists, mitochondrial complex III electron transport inhibitors, mitochondrial complex I electron transport inhibitors, inhibitors of acetyl CoA carboxylase, mitochondrial complex IV electron transport inhibitors, mitochondrial complex II electron transport inhibitors, and further insecticides in a synergistically effective amount, with the proviso that the composition does not comprise Coniothyrium minitans CON/M/91-08 (DSM 9660) and Fluopyram (I247). Furthermore, the present invention relates to a kit of parts comprising said composition and the use of said composition.
