Abstract

The present invention relates to a composition comprising of least one biological control agent. Furthermore, the present invention relates to the use of this composition as well as a method for reducing overall damage of plants and plant parts.

First claim

The invention claimed is:

1. A composition comprising
at least one biological control agent selected from the group consisting of Bacillus subtilis AQ713 (NRRL Accession No. B-21661), Bacillus subtilis AQ30002 (NRRL Accession No. B-50421), and Bacillus subtilis AQ 30004 (NRRL Accession No. B-50455) and
at least one fungicide (I) selected from the group consisting of chlorothalonil, fluopicolide, and propineb,
wherein the weight ratio of the at least one biological control agent and the at least one fungicide (I) lies in the range of 1:500 to 1000:1 and combination of the at least one biological control agent and the at least one fungicide (I) results in a synergistic effect.

2. The composition according to claim 1 , wherein the at least one biological control agent is Bacillus subtilis AQ713 (NRRL Accession No. B-21661).

3. The composition according to claim 2 , wherein fungicide (I) is propineb.

4. The composition according to claim 1 additionally comprising at least one auxiliary selected from the group consisting of extenders, solvents, spontaneity promoters, carriers, emulsifiers, dispersants, frost protectants, thickeners and adjuvants.

5. The composition according to claim 1 wherein the at least one biological control agent is Bacillus subtilis AQ30002 (NRRL Accession No. B-50421).

6. The composition according to claim 2 wherein fungicide (I) is chlorothalonil.

7. The composition according to claim 2 wherein fungicide (I) is fluopicolide.

8. A seed treated with the composition according to claim 1 .

9. 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 selected from the group consisting of Bacillus subtilis AQ713 (NRRL Accession No. B-21661), Bacillus subtilis AQ30002 (NRRL Accession No. B-50421), and Bacillus subtilis AQ 30004 (NRRL Accession No. B-50455) and
at least one fungicide (I) selected from the group consisting of chlorothalonil, fluopicolide, and propineb,
onto the plant, plant parts, harvested fruits, vegetables and/or plant's locus of growth,
wherein the weight ratio of the at least one biological control agent and the at least one fungicide (I) lies in the range of 1:500 to 1000:1 and combination of the at least one biological control agent and the at least one fungicide (I) results in a synergistic effect.

10. The method according to claim 9 wherein the at least one biological control agent is Bacillus subtilis AQ713 (NRRL Accession No. B-21661).

11. A kit of parts comprising
at least one biological control agent selected from the group consisting of Bacillus subtilis AQ713 (NRRL Accession No. B-21661), Bacillus subtilis AQ30002 (NRRL Accession No. B-50421), and Bacillus subtilis AQ30004 (NRRL Accession No. B-50455) and
at least one fungicide (I) selected from the group consisting of chlorothalonil, fluopicolide, and propineb,
in a spatially separated arrangement,
wherein the weight ratio of the at least one biological control agent and the at least one fungicide (I) lies in the range of 1:500 to 1000:1 and combination of the at least one biological control agent and the at least one fungicide (I) in the kit results in a synergistic effect.
