## Abstract

The invention concerns the use of a composition containing a mixture of: (i) at least a fatty acid ester or alkoxylated fatty acid; and (ii) at least a terpenic derivative, as additive enhancing the efficacy of an active plant protective substance, in particular herbicide, fungicide, insecticide or regulating growth.

## Claims

### Claim 1

A composition comprising:
(i) at least one alkoxylated fatty acid ester of the formula:
in which R1 represents a linear or branched, saturated or unsaturated hydrocarbon chain containing from 10 to 30 carbon atoms, and
R2 represents a linear or branched, saturated or unsaturated hydrocarbon chain containing from 1 to 11 carbon atoms; and
(ii) at least one terpene.

### Claim 2 (depends on 1)

The composition according to claim 1, in which R2 represents methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, hexyl, octyl, ethylhexyl, decyl or terpenyl.

### Claim 3 (depends on 1)

The composition according to claim 1, wherein R1 represents a linear or branched, saturated or unsaturated, C16-C22 hydrocarbon chain.

### Claim 4 (depends on 1)

The composition according to claim 1, wherein R1 represents an unsaturated C16-C22 hydrocarbon chain.

### Claim 5 (depends on 1)

The composition according to claim 1, wherein R1 represents a chain of a fatty acid obtained from rapeseed oil, soybean oil, sunflower oil, corn oil, groundnut oil, olive oil, palm oil, flax oil, safflower oil, cottonseed oil, sesame oil or tall oil.

### Claim 6 (depends on 1)

The composition according to claim 1, wherein said compound of general formula I is selected from the group consisting of methyl, butyl, isobutyl and ethylhexyl esters.

### Claim 7 (depends on 1)

A composition according to claim 1, wherein said compound of general formula I is a methyl ester of a fatty acid mixture of tall oil.

### Claim 8 (depends on 1)

The composition according to claim 1, wherein said terpene derivative is a monoterpene or a mixture of monoterpenes.

### Claim 9 (depends on 1)

The composition according to claim 1, wherein said terpene derivative is selected from the group consisting of terpenic carbides, oxidized derivatives of terpenic carbides, terpenic alcohols, terpenic aldehydes and ketones, and mixtures thereof.

### Claim 10 (depends on 1)

The composition according to claim 1, wherein said terpene derivative is a mixture of terpenic carbides and terpenic alcohols.

### Claim 11 (depends on 1)

The composition according to claim 1, wherein said terpene derivative is a pine oil.

### Claim 12 (depends on 1)

The composition according to claim 1, where said terpene derivative is a pine oil containing 90% terpenic alcohols.

### Claim 13 (depends on 1)

The composition according to claim 1, wherein R2 contains 1 to 5 carbon atoms.

### Claim 14 (depends on 1)

The composition according to claim 1 containing 80 to 20% of compound (i) and 20 to 80% of compound (ii).

### Claim 15 (depends on 1)

(ii) pine oil containing 90% terpenic alcohols.

### Claim 17 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

A herbicidal composition comprising a herbicide and the composition of any of claims 1 to 16.

### Claim 18 (depends on 17)
