The aim of our study was to produce and characterize poly-ε-caprolactone (PCL) nanospheres containing essential oils from Zanthoxylum riedelianum fruit evaluate their stability gains as well insecticidal deterrent activities against whitefly (Bemisia tabaci). PCL exhibited a homogeneous spherical morphology, with particle diameters between 106.7 nm 129.2 nm, pH approximately 6, zeta potential (ZP) lower than -19.0 mV encapsulation efficiency higher 98%. Only 43% the nanoencapsulated oil...
Encapsulation via nanotechnology offers a potential method to overcome limited thermal and photo-stability of botanical pesticides. In this study, nanospheres essential oils (NSEO) derived from Zanthoxylum rhoifolium Lam. fruit were characterized evaluated for their photostability insecticidal activity against Bemisia tabaci. Three major compounds Z. fruits detected by CG-MS: β-phellandrene (76.8%), β-myrcene (9.6%), germacrene D (8.3%). The nanoprecipitation was used obtain homogeneous...
The phytopathogenic fungi Sclerotinia sclerotiorum and Rhizopus stolonifer infect different crop plants. Essential oils have been used as an alternative to chemical control methods. Therefore, the objective of this study was analyze essential oil composition stem bark Zanthoxylum riedelianum (ZREO) evaluate its antifungal potential. ZREO obtained by hydrodistillation analyzed using gas chromatography coupled mass spectrometry evaluated for in vitro activity. major components identified...
Commercial ultrasonic baths employ piezoelectric ceramic to generate cavitation. These ceramics vibrate with large amplitudes and their physical characteristics may be changed decreasing of the performance due heating. We develop an experimental study evaluate changes in Butterworth-Van Dyke equivalent electric circuit a disk caused by temperature at range from 30 °C 90 °C, typical commercial baths. The results show that motional resistance is significantly modified increasing mechanical...
