Application of Comb-Type Fluorocarbon Polymer Surfactants as Dispersants in Insecticidal and Fungicidal Suspension Concentrates
Year: 2025
Type: article
Abstract: To investigate the application of novel comb-type fluorinated polymeric surfactants in suspension concentrates (SCs), we used the optimized surfactants (Comb-S 1, Comb-S 2, and Comb-S 3) as dispersants, with commercial dispersants as controls, to prepare 15% indoxacarb SC and 22% iprodione SC, respectively. The physicochemical properties (including suspension rate, particle size, and stability) and indoor biological activity of the prepared SC were determined. Comprehensive data indicated that for 15% indoxacarb SC, the novel comb-type fluorinated polymeric surfactants exhibited good compatibility with commercial dispersants. Whether used in combination or alone, SC demonstrates excellent dispersibility, stability, and application efficacy. For 22% iprodione SC, Comb-S 2 demonstrated good compatibility with commercial dispersants. Furthermore, the fungicidal activity test against Botrytis cinerea showed that Comb-S 2 could not only replace commercial dispersants, but the 22% iprodione SC formulated with Comb-S 2 exhibited more outstanding fungicidal activity.
