Liquid formulations of carboxamide arthropodicides
Disclosed are suspension concentrate compositions comprising by weight based on the total weight of the composition, (a) from about 0.1 to about 50% of one or more carboxamide arthropodicides that are solid at room temperature; ( b) from 0 to about 50% of one or more biologically active agents other than the carboxamide arthropodicides; (c) from about 20 to about 70% of water; (d) from about 10 to about 70% of one or more water-immiscible liquid compounds; and (e) from about 1 to about 55% of a surfactant component having a dispersing property. This invention also relates to a method for controlling an arthropod pest comprising diluting said suspension concentrate composition with water, optionally adding an adjuvant to form a diluted composition, and contacting the arthropod pest or its environment with an effective amount of said diluted composition.
