Abstract

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

and a base.

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.

First claim

We claim:

1. An agrochemical composition comprising a pyripyropene pesticide of formula I

and a base, which is selected from the group consisting of N,N,N′,N′-Tetrakis(2-hydroxypropyl)ethylenediamine and a compound of the formula III

where
R 1 is a radical (A-O) n H,
A is C 2 -C 4 -alkandiyl,
m is an integer from 1 to 50;
n is an integer from 1 to 50, and
R 2 is C 8 -C 24 alkyl or C 8 -C 24 alkenyl.

2. The composition according to claim 1 , wherein the concentration of the base is selected from such a range that after dilution of the composition to a concentration of 1.0 wt % in water a pH of at least 7.0 results.

3. The composition according to claim 1 , where the concentration of the base is in the range from 0.1 to 10 wt %, based on the total weight of the composition.

4. The composition according to claim 1 , wherein the composition comprises no more than 5 wt % water.

5. The composition according to claim 1 , wherein the base has solubility in water of at least 0.1 g/l at 20° C.

6. The composition according to claim 1 , wherein the composition comprises at least 40 wt % water and the base has solubility in water of at least 1.0 g/l at 20° C.

7. The composition according to claim 1 , wherein the base is selected from bases in which a mixture of the base with water at a concentration of 0.1 mol/l has a pH of at least 7.0 in water at 20° C.

8. The composition according to claim 1 , where the base is selected from a compound of the formula III

9. The composition according to claim 1 , further comprising at least one alkoxylated aliphatic alcohol.

10. The composition according to claim 9 , wherein the alkoxylated aliphatic alcohol is selected from one or more compounds of the formula (IV)
R a —O—(C m H 2m O) x —(C n H 2n O) y —(C p H 2p O) z —R b   (IV)

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

11. The composition according to claim 10 , wherein R a represents a linear C 5 -C 36 -alkyl or C 5 -C 36 -alkenyl.

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

13. The composition according to claim 10 , wherein m, n, and p represent, independently of one another, an integer from 2 to 5.

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

15. The composition according to claim 9 , wherein the pesticide is present in dissolved form.

16. The composition according to claim 9 , which is an emulsion concentrate.

17. The composition according to claim 1 , wherein the base is selected from the group consisting of N,N,N′,N′-tetrakis(2-hydroxypropyl)ethylenediamine and a compound of formula III, wherein the compound of formula III is an ethoxylated C 12-20 fatty amine selected from the group consisting of ethoxylated coco amine, ethoxylated oleyl amine, ethoxylated tallow amine, and ethoxylated stearyl amine.

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

19. The composition according to claim 1 , wherein the pesticide is present as an emulsion concentrate.

20. A method for preparing the composition as defined in claim 9 , comprising contacting said pesticide and said base.

21. A method for protecting plants from attack or infestation by insects, acarids or nematodes comprising contacting the plant, or the soil or water in which the plant is growing, with a composition of claim 1 in pesticidally effective amounts.

22. A method for controlling insects, arachnids or nematodes comprising contacting an insect, acarid or nematode or their food supply, habitat, breeding grounds or their locus with a composition according to claim 1 in pesticidally effective amounts.

23. A method for protection of plant propagation material comprising contacting the plant propagation material with a composition as defined in claim 1 in pesticidally effective amounts.

24. Seed treated with the composition according to claim 1 .

25. A method for preparing an aqueous tank-mix comprising
a) providing a composition containing a pesticide of formula I

b) providing a composition containing a base, which base is characterized by an acidity constant of the conjugate acid of at least 7.0, determined in water at 20° C., and which is selected from the group consisting of N,N,N′,N′-Tetrakis(2-hydroxypropyl)ethylenediamine and a compound of formula III

where
R 1 is a radical (A-O) n H,
A is C 2 -C 4 -alkandiyl,
m is an integer from 1 to 50,
n is an integer from 1 to 50, and
R 2 is C 8 -C 24 -alkyl or C 8 -C 24 -alkenyl;
 and
c) contacting water and the compositions of steps a) and b).

26. Kit of parts comprising, as separate components, a) a pesticide-of formula I
