Abstract
An aqueous suspoemulsion, characterized in that it contains at least the two components: (a) a dispersed oil phase comprising: (i) lambda-cyhalothrin as the first active ingredient, and (ii) at least one C9-C10 aromatic hydrocarbon solvent having lambda-cyhalothrin dissolved therein; (b) a continuous water phase containing: (i) at least one water-insoluble second active ingredient which is suspended in the continuous phase; and (ii) a dispersing agent in an amount sufficient to disperse the water-insoluble active ingredient. Methods of making and using this suspoemulsion are also disclosed.
Claims16
An aqueous suspoemulsion, comprising:
- (a) a dispersed oil phase comprising:
- (i) a first active ingredient comprising lambda-cyhalothrin,
- (ii) a solvent that stabilizes said lambda-cyhalothrin consisting essentially of C9 aromatic hydrocarbons, C10 aromatic hydrocarbons, or a combination of C9 aromatic hydrocarbons and C10 aromatic hydrocarbons, and the solvent having a flash point from around 122° F. to around 151° F. and present in an amount to establish a weight ratio of lambda-cyhalothrin to solvent of from 1:10 to 10:1, wherein at least a portion of the lambda-cyhalothrin is dissolved therein;
- (b) a continuous aqueous phase comprising:
- (i) at least one second active ingredient that is insoluble or sparingly soluble in water and insoluble in the solvent, which is suspended in the continuous phase,
- (ii) a dispersing agent to disperse the water-insoluble active ingredient in the continuous phase, and
- (iii) water;
- wherein the second active ingredient is selected from the group consisting of Imidacloprid, Thiamethoxam, dinotefuran, Emamectin benzoate, Abamectin, Flufenoxuron, Lufenuron, Chlorfenapyr, Diafenthiuron, Pirimiphos-methyl, Phenthoate, Fluacrypyrim, Chlorpyrifos, Tebufenpyra, Spirodiclofen, Tolfenpyrad, Spinosad, Methoxyfenozide, Thifluzamide, Tebuconazole, Sulfoxaflor, Fipronil, Profenofos, Pymetrozine, Phoxim, Spiromesifen, Chlorfluazuron, and mixtures thereof;
- and wherein said lambda-cyhalothrin is stable in said solvent of the suspoemulsion to provide less than 3% degradation after storage for 14 days at 54° C.
