Abstract

The present invention relates to a method for preparing a tank mix, which comprises the step of contacting a pesticide formulation, water, and a tank mix adjuvant which comprises a carbonate of the formula (I); to a pesticide formulation comprising the tank mix adjuvant; to a method of controlling phytopathogenic fungi and/or undesired vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the tank mix or the pesticide formulation is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil and/or on undesired plants and/or the crop plants and/or their environment; and to a use of the tank mix adjuvant for increasing the efficacyl of a pesticide.

First claim

We claim:

1. A pesticide formulation comprising a pesticide and a tank mix adjuvant which comprises a carbonate of the formula (I)

where R a is a C 1-12 alkyl, or a n-valent radical derived by abstraction of the OH groups of an n-valent polyol and which is substituted by n minus 1 carbonate groups of the formula (II)

where n is from 2 to 4 and the polyol is an aliphatic polyol comprising 2 to 10 carbon atoms;
wherein the tank mix adjuvant contains less than 5 wt % of pesticides.

2. The formulation of claim 1 , wherein the pesticide is present in dissolved form.

3. The formulation of claim 1 , in form of a liquid.

4. The formulation of claim 1 , wherein the weight ratio of the pesticide to the carbonate of the formula (I) is from 1:1 to 1:100.

5. The formulation of claim 1 , wherein R a is a linear, or branched C 1-10 alkyl or the index n is 2 or 3 and the polyol is an aliphatic polyol comprising 2 to 8 carbon atoms.

6. The formulation of claim 1 , wherein R a is methyl, ethyl, n-butyl, iso-butyl, n-hexyl, branched octyl, branched decyl, or n is 2, the polyol is 1,2-ethanediol, 1,4-butanediol or 2,2-dimethyl-1,3-propanediol.

7. A method of controlling phytopathogenic fungi, and/or undesired vegetation, and/or undesired insect or mite attack, and/or for regulating the growth of plants, the formulation of claim 1 , or a tank mix comprising the formulation, is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil, and/or on undesired plants, and/or the crop plants, and/or their environment.

8. The method of claim 7 , wherein the pesticide is present in dissolved form.

9. The method of claim 7 , in form of a liquid.

10. The method of claim 7 , wherein the weight ratio of the pesticide to the carbonate of the formula (I) is from 1:1 to 1:100.

11. The method of claim 10 , wherein R a is a linear, or branched C 1-10 alkyl, or the index n is 2 or 3 and the polyol is an aliphatic polyol comprising 2 to 8 carbon atoms.

12. The method of claim 11 , wherein R a is methyl, ethyl, n-butyl, iso-butyl, n-hexyl, branched octyl, branched decyl, or n is 2, the polyol is 1,2-ethanediol, 1,4-butanediol or 2,2-dimethyl-1,3-propanediol.
