FACTORS AFFECTING THE STABILITY OF SIR-8514 (2-CHLORO-N-[[[4-(TRIFLUOROMETHOXY)PHENYL]AMINO]CARBONYL]BENZAMIDE) UNDER LABORATORY AND FIELD CONDITIONS

SIR-8514 (2-chloro-N-[N-4-(trifluoromethoxv) phenyl] amino] carbonyl]benzamide) is a potent inhibitor of mosquito larval development. Its stability in water is greatly reduced as temperature and pH both become relatively high. Its persistence is not greatly affected by sunlight. In water having a high organic matter content, its persistence appears to be affected by adsorption and by microbial degradation. SIR-8514 is stable on vegetation under field conditions; residues on vegetation can be minimized by application of sand granule formulations. The biological and chemical properties of SIR-8514 are similar to those of diflubenzuron (2, 6-difluoro-Ar-[[[4-chlorophenyl]amino]carbonyl]benzamide). © 1979, American Chemical Society.
