Abstract:

Fourteen novel heptafluoroisopropyl-containing benzoylphenylureas were designed and synthesized. Their insecticidal activities against armyworm (Pseudaletia separata Walker) were examined and compared with the commercial product diflubenzuron. Three compounds (III, IIJ, and IIk) showed excellent insecticidal effect, and their activity resembled that of diflubenzuron. Compound III also showed nearly the same insecticidal activity as novaluron on African cotton leafworm (Spodoptera littoralis). Furthermore, results from a field trial indicated that 5% EC III exhibited similar efficacy in comparison with chlorfluazuron and hexaflumuron against imported cabbage worm (Pieris rapae L.) and diamondback moth (Plutella xylostella), respectively. © 2009 American Chemical Society.
