Water-Based Environmentally Friendly Pesticide Formulations Based on Cyclodextrin/Pesticide Loading System

Difenoconazole (DIF) is a representative variety of broad-spectrum triazole fungicides and liposoluble pesticides. However, the water solubility DIF so poor that its application limited in plant protection. In addition, conventional formulations always contain abundant organic solvents, which may cause pollution environment. this study, two DIF/cyclodextrins (CDs) inclusion complexes (ICs) were successfully prepared, DIF/β-CD IC DIF/hydroxypropyl-β-CD (DIF/HP-β-CD IC). The effect cyclodextrins on antifungal pesticide investigated. According to phase test, molar ratio apparent stability constant ICs obtained. Fourier transform infrared spectroscopy, thermal gravity analysis, X-ray diffraction scanning electron microscopy used systematically characterize formation characteristics ICs. results noted entered cavities CDs. test proved better performance DIF/HP-β-CD IC, exceeded emulsifiable concentrate. Therefore, our study provides informative direction for intelligent use pesticides with develop water-based environmentally friendly formulations.
