Abstract

Agrochemical compositions are described which contain a carboxylic acid salt of dodecylguanidine and a compatibility agent for slowing down the dissociation reaction of the carboxylic acid salt of dodecylguanidine in an aqueous medium. Also, the formation of anionic dodecylguanidine is suppressed or prevented. The ratio of the dodecylguanidine acetate to that of the compatibility agent in the agricultural compositions is below 5.0, preferably between 3.0 and 0.5, more preferably equals 1.4.

Claims

1. An agrochemical composition comprising dodecylguanidine acetate (dodine) and a compatibility agent for slowing down the dissociation reaction of dodine in an aqueous medium thereby suppressing or preventing the formation of anionic dodecylguanidine, wherein the compatibility agent is an alkali metal acetate or earth alkali metal acetate, and the ratio of the dodecylguanidine acetate to that of the compatibility agent in the composition is from 0.5 to 5.0 and wherein the agrochemical composition is in the form of wettable granules or a wettable powder.

2. The agrochemical composition according to claim 1, wherein the compatibility agent is sodium acetate.

3. The agrochemical composition according to claim 1, wherein the composition further comprises an anionic surfactant.

4. A tank-mix prepared by mixing the composition of claim 1 with water and an active ingredient selected from the group consisting of pesticides, fertilizers, biocides and combinations thereof.

5. The tank-mix according to claim 4, wherein the compatibility agent is sodium acetate.

6. The tank-mix according to claim 4, wherein the active ingredient is a pesticide selected from the group consisting of spirodiclofen, pyrimethanil and methoxyfenozide.

7. The tank-mix according to claim 4, wherein the composition further comprises an anionic surfactant.

8. The tank-mix according to claim 7, wherein the anionic surfactant comprises an alkylnaphthalene sulphonate or a lignosulphonate.

9. A method for preparing an aqueous tank-mix of dodine, comprising the steps of:

adding the agrochemical composition of claim 1 to a spray tank holding water to form an aqueous mixture, and

adding to the aqueous mixture an active ingredient selected from the group consisting of pesticides, fertilizers, biocides and combinations thereof, to obtain an aqueous tank-mix.

10. The method according to claim 9, wherein the compatibility agent is sodium acetate.

11. The method according to claim 9, wherein the tank-mix further comprises a lignosulphonate or an alkylnaphthalene sulphonate.

12. The agrochemical composition according to claim 1, wherein the ratio of dodine to of the compatibility agent is from 0.5 to 3.0.

13. The agrochemical composition according to claim 1, wherein the ratio of dodine to compatibility agent equals 1.4.

14. The agrochemical composition according to claim 3, wherein the anionic surfactant comprises an alkylnaphthalene sulphonate.

15. The tank-mix according to claim 4, wherein the ratio of dodine to the alkali metal acetate anion or earth alkali metal acetate anion in the tank-mix is from 0.5 to 3.0.

16. The tank-mix according to claim 4, wherein the ratio of dodine to the alkali metal acetate anion or earth alkali metal acetate anion in the tank-mix equals 1.4.

17. The method according to claim 9, wherein the ratio of dodine to the compatibility agent is from 0.5 to 3.0.

18. The method according to claim 9, wherein the ratio of dodine to the compatibility agent equals 1.4.
