Abstract

The development of nanomaterials could support more extensive agricultural uses, including nano-pesticides. Current study was conducted to observe the effects of different concentrations (25, 50, 75, 100, 150 and 200 ppm) of biosynthesized zinc oxide nanoparticles (ZnO NPs) and aluminum oxide nanoparticles (Al₂O₃NPs) on soil, faba bean and toxicity on black aphid (Aphis fabae). The synthesized ZnO NPs from Musa paradisiaca L. characterized by ultraviolet (UV)-visible spectroscopy, Fourier Transform Infrared Spectroscopy, X-ray diffraction and Transmission electron microscopy. Al₂O₃ NPs was prepared by calcination of Iraqi kaolin via evaporation process. Highest pH (8.21) and soil organic matter (2.62%) were observed in the sprayed pots with 75 ppm of ZnO NPs, while the highest values in the sprayed pots with Al₂O₃ NPs were 8.24 in 100 ppm and 1.73% in 75 ppm. Taller plants (53 cm) and more leaf numbers (54 leaf per plant) were observed in 75 ppm of ZnO NPs sprayed pots. Greater branch number was detected in 100 ppm ZnO NPs sprayed pots. All sprayed pots with ZnO NPs showed less chlorophyll contents when compared with control. Spraying pots with Al₂O₃ NPs showed different results. Taller plants (56 cm) were observed in 75 ppm. More leaf numbers (40 leaf per plant) were observed in 25 ppm. Whereas negative effects were observed on number of branches and leaf chlorophyll contents. Faba bean spraying with ZnO NPs and Al₂O₃ NPs induced significant effects on black aphid mortality indicating their great insecticidal activities at different doses, and this considered as the first performance in Kurdistan Region regarding to insecticidal habit of nanoparticles.
