Abstract

The present invention relates to a composition comprising a first salt, which contains a first anionic pesticide (A1) and a cationic polyamine (B), and a second salt, which contains a second anionic pesticide (A2) and a cationic polyamine (B), wherein both salts contain the same cationic polyamine (B), and wherein the cationic polyamine comprises at least two amino groups. The disclosure further relates to methods for preparing the composition, methods for combatting harmful insects and/or phytopathogenic fungi using the composition, methods for controlling undesired vegetation using the composition, and seeds including the composition.

First claim

We claim:

1. An aqueous stable pesticidal composition consisting essentially of:
a) a first salt, which contains a first anionic pesticide (A1) and a cationic polyamine (B),
b) a second salt, which contains a second anionic pesticide (A2) and a cationic polyamine (B), and
c) water,
wherein the first salt and the second salt are present in dissolved form in the water,
wherein the anionic pesticides and the polyamine are combined in such a molar ratio which results in a pH of 6.5 to 9.0,
wherein the first and the second anionic pesticides are selected from the group consisting of dicamba and glyphosate;
wherein the first anionic pesticide and the second anionic pesticide are different anionic pesticides;
wherein both salts contain the same cationic polyamine (B), and wherein the cationic polyamine comprises at least two amino groups, and
wherein the cationic polyamine (B) is selected from the group consisting of a compound of formula (B1.1) and a compound of the formula (B1.2):

2. The composition of claim 1 , wherein the molar ratio of the sum of the first and the second anionic pesticide to the sum of the cationic polyamines is in the range from 1.5 : 1 to 4 : 1.

3. A method for preparing the composition of claim 1 , comprising mixing the first salt and the second salt.

4. A method of combating harmful insects and/or phytopathogenic fungi, which comprises contacting plants, seed, soil or habitat of plants in or on which the harmful insects and/or phytopathogenic fungi are growing or may grow, plants, seed or soil to be protected from attack or infestation by said harmful insects and/or phytopathogenic fungi with an effective amount of the composition of claim 1 .

5. The method of claim 4 , wherein the cationic polyamine is a compound of formula (B1.1):

6. A method of controlling undesired vegetation, which comprises applying a herbicidal effective amount of the composition of claim 1 to plants, habitat or on seed of said plants.

7. A seed treated with the composition of claim 1 .

8. The composition of claim 1 , wherein the cationic polyamine is the compound of formula (B1.1).

9. The composition of claim 1 , wherein the cationic polyamine is the compound of formula (B1.2).
