## Abstract

Use of sophorolipids as adjuvants in combination with pesticides as tank mix additive and/or as formulation additive for crop protection and for the industrial non-crop sector.

## Claims

### Claim at position 1

-10. (canceled)

### Claim 11

A composition comprising
a) at least one of a sophorolipid, a sophorolipid preparation, and derivatives thereof obtainable by fermentative preparation, and at least one
b) active pesticidal ingredient
with the proviso that component (a) has no inherent pesticidal activity.

### Claim 12 (depends on 11)

The composition as claimed in claim 11 wherein a pesticidal efficacy and activity of the composition is greater than the sum of the efficacies of the individual components.

### Claim 13 (depends on 11)

The composition as claimed in claim 11, wherein component a) is present in an adjuvant, based on the solids, with a fraction of >30% by weight in the adjuvant.

### Claim 14 (depends on 11)

A composition as claimed in claim 11, wherein fermentative preparation includes a hydrophobic substance selected from the group consisting of hydrocarbons, fatty acids, fatty acid esters, fatty alcohols and mixtures thereof.

### Claim 15 (depends on 11)

A composition as claimed in claim 11, wherein component a) is in purified or unpurified form, and
i) is present as a mixture of lactone and acid form, with an acid fraction of 10% to less than 60% by weight, or
ii) consists to a fraction of >90% by weight of the lactone form, which can be solubilized by adjustment of pH to a level of between 6 and 8, or
iii) is present as methyl or ethyl ester, with a fraction of 1% to 100% by weight of the respective ester.

### Claim 16 (depends on 11)

A composition as claimed in claim 11, wherein component a) is a sophorolipid of formula 1 or 1a,
where
R1 and R2 independently of one another are either H or an acetyl group,
R3 is H or a methyl, ethyl or hexyl group,
R4 independently at each occurrence is a saturated or unsaturated divalent, branched or unbranched organic group,
R5 is H or a methyl group,
with the proviso that the total number of the carbon atoms in groups R4 and R5 does not exceed the number 29.

### Claim at position 8
