Abstract

The present invention relates to a compositions comprising a pyripyropene pesticide of the formula (I) or (II) as defined below

and an adjuvant.

The present invention relates also to methods of preparing and applying such compositions, as well as several uses thereof, and finally seeds, comprising said composition.
The invention also relates to an aqueous pesticide formulation comprising a pesticide compound of the formula I as defined in claim 1 in the form of fine particles suspended in an aqueous liquid.

First claim

We claim:

1. A composition comprising a pyripyropene pesticide of formula I or of formula II

or crystalline hydrates thereof;
and an adjuvant, where the composition is in the form of an emulsifiable concentrate comprising at least 10 wt % of the adjuvant, based on the composition and where the adjuvant comprises
an alkoxylated aliphatic alcohol.

2. The composition according to claim 1 , wherein the pyripyropene pesticide is the pesticide of formula I.

3. The composition according to claim 1 , further comprising a surfactant which carries at least one poly-C 2 -C 4 -alkyleneoxide moiety selected from polyethoxylated sorbitan fatty acid esters, poly(ethyleneoxide-co-propylenoxide) copolymers and poly-C 2 -C 4 -alkyleneoxide modified polydimethylsiloxanes.

4. The composition according to claim 1 , further comprising a silicone-based adjuvant.

5. The composition according to claim 1 , further comprising a silicone-based adjuvant comprising a poly-C 2 -C 4 -alkyleneoxide modified polydimethylsiloxane.

6. The composition according to claim 1 , further comprising a crop oil concentrate.

7. The composition according to claim 6 , wherein the crop oil concentrate contains at least one hydrocarbon solvent and at least one non-ionic surfactant.

8. The composition according to claim 1 , wherein the alkoxylated aliphatic alcohol is selected from alkoxylates of the formula (A)
R a —O—(C m H 2m O) x —(C n H 2n O) y —(C p H 2p O) z -R b   (A)

in which
R a represents C 5 -C 36 -alkyl, C 5 -C 36 -alkenyl or a mixture thereof;
R b represents H or C 1 -C 12 -alkyl;
m,n,p represent, independently of one another, an integer from 2 to 16;
x, y, z represent, independently of one another, a number from 0 to 100; and
x+y+z corresponds to a value from 1 to 100.

9. The composition according to claim 8 , wherein R a represents a linear C 5 -C 36 -alkyl, C 5 -C 36 -alkenyl, or a mixture thereof.

10. The composition according to claim 8 , wherein R a represents a linear C 14 -C 36 -alkyl, C 14 -C 36 -alkenyl, or a mixture thereof.

11. The composition according to claim 8 , wherein m, n, p represent, independently of one another, an integer from 2 to 5.

12. The composition according to claim 8 , wherein x+y+z corresponds to a value from 10 to 30.

13. A composition comprising a pyripyropene pesticide of formula I or of formula II

and an adjuvant, where the composition is in the form of a tank-mix, which contains 0.01 to 5 wt %, based on the total weight of the tank mix of the adjuvant and where the adjuvant comprises an alkoxylated aliphantic alcohol.

14. The composition according to claim 13 , further comprising a crop oil concentrate.

15. The composition according to claim 13 , further comprising a silicone-based adjuvant comprising a poly-C 2 -C 4 -alkyleneoxide modified polydimethylsiloxane.

16. The composition according to claim 1 , wherein the pesticide is present in dissolved form or in suspended form.

17. A method for preparing the composition as defined in claim 1 , which method comprises contacting said pesticide and said adjuvant.

18. A method for preparing an aqueous tank-mix comprising the steps of
a) providing a composition containing a pesticide of formula I or of formula II

b) providing a composition containing an adjuvant, which is an alkoxylated aliphantic alcohol; and
c) contacting compositions of steps a) and b).

19. Kit of parts comprising, as separate components,
a) a pesticide of formula I or of formula II

b) an adjuvant, which is an alkoxylated aliphatic alcohol
for combined use.

20. The composition of claim 1 , wherein the pyripyropene pesticide is a crystalline hydrate of the compound of formula I

which, in an X-ray powder diffractogram at 25° C. and Cu—K α radiation, shows at least four of the following reflexes, given as 2θ values: 9.7±0.2°, 10.3±0.2°, 11.3±0.2°, 14.0±0.2°, 15.5±0.2°, 16.4±0.2°, 17.6±0.2°.

21. The composition of claim 1 , wherein the pyripyropene pesticide is a crystalline hydrate of the compound of formula I

which, in an X-ray powder diffractogram at 25° C. and Cu—K α radiation, shows at least four of the following reflexes, given as 2θ values: 8.0±0.2°, 9.5±0.2°, 10.7±0.2°, 11.0±0.2°, 11.2±0.2°, 11.7±0.2°, 14.2±0.2°, 15.6±0.2°, 16.5±0.2°, 17.7±0.2°, 21.5±0.2°.

22. The composition of claim 1 , wherein the pyripyropene pesticide is a crystalline hydrate of the compound of formula I

which, in an X-ray powder diffractogram at 25° C. and Cu—K α radiation, shows at least four of the following reflexes, given as 2θ values: 7.5±0.2°, 9.6±0.2°, 11.0±0.2°, 11.7±0.2°, 12.1±0.2°, 12.5±0.2°, 15.8±0.2°, 16.3±0.2°, 17.4±0.2°, 19.3±0.2° and 19.6±0.2°.
