Abstract

The present invention relates to a method for increasing the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure, wherein the plants, the plant propagules, the seed of the plants and/or a locus where the plants are growing or are intended to grow are treated with an effective amount of a composition comprising a Bacillus subtilis strain with Accession No. NRRL B-21661, a mutant of the strain having all the identifying characteristics of the strain, or a cell-free extract thereof; wherein the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure is increased and the increase in vigor is characterized by less fertilizer needed.

First claim

What is claimed is:

1 . A method for increasing the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure,
wherein the plants, the plant propagules, the seed of the plants and/or a locus where the plants are growing or are intended to grow are treated with an effective amount of a composition comprising a Bacillus subtilis strain with Accession No. NRRL B-21661, a mutant of the strain having all the identifying characteristics of the strain, or a cell-free extract thereof, wherein the vigor and/or crop yield of agricultural plants under essentially non-existent pathogen pressure is increased and the increase in vigor is characterized by less fertilizer needed.

2 . The method as claimed in claim 1 , wherein a commercially available formulation of the Bacillus subtilis strain is used.

3 . The method as claimed in claim 1 , further comprising treating the plants, the plant propagules, the seed of the plants and/or a locus where the plants are growing or are intended to grow with an effective amount of at least one chemical compound as component (II), selected from the active compound groups A) to J):
