Abstract

Tetraniliprole containing formulations and methods for using them for controlling rootworm infestation are discussed. The formulations of the present invention provide improved delivery active ingredients by the ability to provide substantially higher degree of control as compared to other diamide counterparts.

First claim

The invention claimed is:

1. A liquid agricultural formulation consisting essentially of (a) a sole active insecticidal component selected from the group consisting of tetraniliprole present in an amount of from 1 to 35% by weight of the formulation, and (b) a carrier system, wherein the agricultural formulation is in the form of a microemulsion, an oil-in-water concentrated emulsion, a suspension, a suspension concentrate, an emulsifiable concentrate, or a microencapsulate and is effective in inducing mortality in at least 60% of Diabrotica rootworm larvae and wherein said formulation excludes chlorantraniliprole.

2. The formulation of claim 1 , wherein the carrier system comprises at least one foaming agent and at least one foam stabilizer.

3. The formulation of claim 1 , wherein the formulation is in the form of a suspension concentrate.

4. The formulation of claim 3 , wherein the tetraniliprole is present in an amount of from 1 to 5 wt % of the formulation composition.

5. A liquid agricultural formulation consisting essentially of (a) tetraniliprole present in an amount of from 1 to 35% by weight of the formulation, (b) a carrier system, wherein the agricultural formulation is in the form of a microemulsion, an oil-in-water concentrated emulsion, a suspension, a suspension concentrate, an emulsifiable concentrate, or a microencapsulate and is effective in inducing mortality in at least 60% of Diabrotica rootworm larvae and wherein said formulation excludes chlorantraniliprole, and further comprising (c) a plant protecting agent selected from the group consisting of insecticides, pesticides, fungicides, herbicides, fertilizers and combinations thereof.

6. The formulation of claim 5 , wherein the plant protecting agent is a pyrethroid insecticide selected from the group consisting of: acrinathrin; allethrin; bifenthrin; cyfluthrin; cypermethrin; alpha-cypermethrin; beta-cypermethrin; zeta-cypermethrin; deltamethrin; esfenvalerate; etofenprox; fenpropathrin; fenvalerate; flucythrinate; tau-fluvalinate; permethrin; silafluofen; gamma-cyhalothrin; and tralomethrin.

7. The formulation of claim 6 , wherein the plant protecting agent is bifenthrin.
