Abstract

This invention relates to compositions compatible with liquid fertilizers and methods of use thereof.

First claim

What is claimed is:

1. A fluid thixotropic fertilizer-compatible pesticidal composition substantially free of surfactants comprising:
(a) at least one agrochemically active compound;
(b) a metal lignosulfate salt, wherein said metal lignosulfate salt is a non-surface active dispersant;
(c) a at least one lubricant selected from silica or alumina;
(d) a water soluble salt of a strong acid; and
(e) water;
wherein the agrochemically active compound is in the form of solid particles, wherein the solid particles have an average diameter from 1 nm to 100 microns and are of a sufficiently small average diameter to be effectively dispersed in the composition and the metal lignosulfate salt and water soluble salt are present in a ratio of from about 2:1 to about 1:20 and are combined in amounts effective to disperse the particles in the water.

2. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is an insecticide.

3. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is a insecticide of formula (I)

wherein
R is hydrogen, acyl, alkyl, aryl, aralkyl, heteroaryl or heteroarylalkyl;
A is hydrogen, acyl, alkyl, aryl, or a bifunctional group that is linked to Z;
E is NO 2 , CN, or a halogenoalkylcarbonyl group;
X is —CR′═ or ═N—, wherein R′ is hydrogen or a bifunctional group linked to Z;
Z is alkyl, —OR″, —SR″, or —NR″R″, or Z is a group linked to (i) the radical A or (ii) the radical X or (iii) both A and X;
provided that when E is CN, Z is not methyl and R is not a (6-chloro-3-pyridyl)methyl

 radical.

4. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is

5. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is imidacloprid, thiamethoxam, thiacloprid, clothianidin, nitenpyram, nithiazine, or dinotefuran.

6. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is a herbicide.

7. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is a fungicide.

8. A fluid thixotropic composition according to claim 1 wherein the agrochemically active compound is a plant growth regulant.

9. The composition of claim 1 wherein the agrochemically active compound and metal lignosulfate salt are present at a ratio of from about 60:1 to about 1:10.

10. The composition of claim 1 wherein the particles are from about 2 to 4 microns average diameter.

11. The composition of claim 1 wherein the metal lignosulfate salt is an alkali metal lignosulfate salt or an alkaline earth metal lignosulfate salt.

12. The composition of claim 1 wherein the water soluble salt of a strong acid is LiCl, NaCl, KCl, MgCl 2 , CaCl 2 , FeCl 3 , NH 4 NO 3 , Mg(NO 3 ) 2 , NaNO 3 , K 3 PO 4 , (NH4) 2 SO 4 , Na 2 SO 4 , or ZnSO 4 .

13. A product comprising a composition according to claim 1 and an agriculturally acceptable liquid fertilizer for simultaneous, separate, or sequential application for control of pests at a locus.

14. A fluid thixotropic composition of claim 1 , wherein said agrochemically active compound is imidacloprid.

15. A fluid thixotropic composition of claim 1 , wherein said at least one lubricant is silica and alumina.

16. A fluid thixotropic composition of claim 1 , wherein said metal lignosulfate salt comprises sodium lignosulfate, potassium lignosulfate, lithium lignosulfate, or calcium lignosulfate.

17. A fluid thixotropic composition of claim 16 , wherein said metal lignosulfate salt comprises sodium lignosulfate.

18. A fluid thixotropic composition of claim 1 , wherein said water soluble salt of a strong acid comprises KCl.

19. A fluid thixotropic composition of claim 1 further comprising an organic sulfonate.

20. A fluid thixotropic composition of claim 19 , wherein said organic sulfonate comprises ammonium salt of alkyl naphthalene sulfonate, sodium salt of alkyl naphthalene sulfonate, or calcium salt of alkyl naphthalene sulfonate.

21. A fluid thixotropic composition of claim 1 , wherein
(a) said at least one agrochemically active compound comprises imidacloprid;
(b) said metal lignosulfate salt comprises sodium lignosulfate, potassium lignosulfate, lithium lignosulfate, or calcium lignosulfate; and
(c) said water soluble salt of a strong acid comprises LiCl, NaCl, KCl, MgCl 2 , CaCl 2 , FeCl 3 , NH 4 NO 3 , Mg(NO 3 ) 2 , NaNO 3 , K 3 PO 4 , (NH4) 2 SO 4 , Na 2 SO 4 , or ZnSO 4 .

22. A fluid thixotropic composition of claim 1 , wherein said fluid thixotropic fertilizer-compatible pesticidal composition is free of surfactants.

23. A fluid thixotropic composition free of a surfactant comprising:
(a) an agrochemically active compound;
(b) a metal lignosulfate salt, wherein said metal lignosulfate salt is a non-surface active dispersant;
(c) a water soluble salt of a strong acid; and
(d) water;
wherein the compound is in the form of solid particles and/or liquid globules of sufficiently small average diameter to be effectively dispersed in the composition and wherein the metal lignosulfate salt and water soluble salt are combined in amounts effective to disperse the particles and/or globules in the water.
