Abstract

Insecticidal compositions suitable for use in preparation of insecticidal liquid fertilizers comprising a pyrethroid, a hydrated aluminum-magnesium silicate, and at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester are disclosed.

Claims (20)

1. An insecticidal fertilizer composition comprising

a) bifenthrin;

b) a hydrated aluminum-magnesium silicate;

c) at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester; and

d) a liquid fertilizer

wherein the liquid fertilizer is present in a concentration of from 95.0% by weight to 99.99% by weight based upon the total weight of all components in the composition.

2. A composition comprising

a) from 0.75% to 1.25% of bifenthrin;

b) from 0.05% to 1.0% of hydrated aluminum-magnesium silicate;

c) from 0.1% to 0.75% of at least one dispersant selected from the group consisting of a sucrose ester, a lignosulfonate, an alkylpolyglycoside, a naphthalenesulfonic acid formaldehyde condensate and a phosphate ester; and

d) from 95% to 99.99% of a liquid fertilizer;

wherein all % are % by weight based upon the total weight of all components in the composition.

3. The composition of claim 1 , wherein the hydrated aluminum-magnesium silicate is selected from the group consisting of montmorillonite and attapulgite.

4. The composition of claim 1 , wherein the phosphate ester is selected from the group consisting of a nonyl phenol phosphate ester and a tridecyl alcohol ethoxylated phosphate potassium salt.

5. The composition of claim 1 , further comprising at least one of an anti-freeze agent, an anti-foam agent and a biocide.

6. The composition of claim 1 , further comprising an insecticidally effective amount of one or more additional insecticides selected from the group consisting of imidacloprid, flonicamid, nithiazine, thiamethoxam, dinotefuran, nitenpyram, thiacloprid, clothianadin and chlorfenapyr.

7. The composition of claim 2 , wherein the hydrated aluminum-magnesium silicate is selected from the group consisting of montmorillonite and attapulgite.

8. The composition of claim 2 , wherein the phosphate ester is selected from the group consisting of a nonyl phenol phosphate ester and a tridecyl alcohol ethoxylated phosphate potassium salt.

9. The composition of claim 2 , further comprising at least one of an anti-freeze agent, an anti-foam agent and a biocide.

10. The composition of claim 2 , further comprising an insecticidally effective amount of one or more additional insecticides selected from the group consisting of imidacloprid, flonicamid, nithiazine, thiamethoxam, dinotefuran, nitenpyram, thiacloprid, clothianadin and chlorfenapyr.
