Abstract

The present invention relates to a new method for pest control and/or for preventing or treating pest infestation. Said method comprises the inoculation of plants, parts of plants or the surrounding of said plants with an effective amount of endophytic Beauveria bassiana strains. In a further aspect the present invention relates to the use of an isolated Beauveria bassiana strain having superior properties. Furthermore, biopesticides and compositions for pest control, in particular, for control of herbivorous insects and/or plant pathogens, are provided.

Claims

1. A method for pest control comprising inoculation of plants, parts of plants or the surrounding of said plants with an effective amount of endophytic Beauveria bassiana strains, in particular, of Beauveria bassiana strain ATP02, DSM 24665.

3. The method according to claim 1 wherein the plant, parts of plants or the surrounding of said plants is selected from leaf, seed, soil, stems, branches, roots, in particular, seeds.

4. The method according to claim 1, wherein the plants are crops.

5. The method according to claim 1, wherein the plants are crops selected from vicia faba, rapeseed, chickpea, maize, sorghum, broad bean, cotton, tobacco, soy, banana, coffee, tomato, cocoa plants, cabbage, corn, bean, potato, opium poppy, date palm, pine, wheat, rice, cereals, barley.

6. The method according to claim 1, wherein the plants are selected from rapeseed, Brassica napus, cotton, maize, corn, and soy.

7. The method according to claim 1, comprising the step of coating seeds or inoculating seeds of plants with the endophytic Beauveria bassiana strains.

8. The method according to claim 1, wherein the pests are insects.

9. The method according to claim 1, wherein the pests are insects selected from herbivorous insects and plant pathogens, in particular, Helicoverpa armigera, Spodoptera spp., Trialeurodes vaporariorum, Plutella xylostella.

2. A method for treating or preventing plants against pest infestation comprising the step of inoculation of said plants, parts of said plants or the surroundings of said plants with an endophytic Beauveria bassiana strain, in particular with the Beauveria bassiana strain ATP02, DSM 24665.

10. Bio-pesticide containing Beauveria bassiana strain ATP02 (DSM 24665).

12. The bio-pesticide or composition according to claim 10 in form of a solution, a dispersion, spore suspension, sclerotia, emulsion, gel, layer, cream, coating, dip, encapsulated or granule.

11. Composition containing Beauveria bassiana strain ATP02, DSM 24665, as an active component for pest control, in particular, for control of herbivorous insects and/or plant pathogens.

13. Use of Beauveria bassiana strain ATP02 for endophytic colonisation of plants.

14. The use according to claim 13 for the colonisation of vicia faba, maize or corn, broad bean, sorghum, tobacco, rapeseed, soy, chickpea, cotton, banana, coffee, tomato, cocoa, cabbage, corn, bean, potato, opium poppy, date palm, pine, wheat, rice, cereals, barley plants.
