摘要：

Copper, iron and zinc nanoparticles (NPs) were synthesized with aqueous extract of Tridax procumbens. The NPs were characterized with UV-Vis, Fourier-transform infrared (FTIR), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and energy-dispersive X-ray spectroscopy (EDX). The maximum absorbance for Cu, Fe and Zn NPs occurred at 300, 318 and 306 nm respectively. Prominent bands on the FTIR spectra established that phyto-compounds in T. procumbens extract are creditable for the reduction and stabilizing process to produce particles ranging from 2.98-100 nm. The nanoparticles were evaluated for their nematicidal activities in field trials on cabbage plants in comparison with the standard nematicide carbofuran. Potent nematicidal activity was notably displayed by the NPs at 100 ppm on Meloidogyne incognita population in 200 cc of soil, number of eggs and gall index. Significantly higher yield was recorded in cabbage plants treated with T. procumbens CuNP contrary to other NPs and untreated cabbage plants. CuNPs can be applied in M. incognita management in place of synthetic nematicides for sustainable cabbage production.
