Abstract
Biologically produced nanoparticles are widely
used in various fields, including agriculture and health. Nanotechnology
research indicates that green chemistry approaches might provide
technologically significant nanomaterials. Zinc oxide nanoparticles appear to
have low effect on human cells and a significant toxicity to microbes. The
advantages of ZnO Nanoparticles are their low cost, safety and easy of
preparation. Zinc oxide (ZnO) is a metal oxide that is GRAS (Generally
recognized as safe) according to the US FDA. The presence of illnesses and
insect pests has caused the output of cotton to decline in recent years,
instead of increasing. One of the most dangerous pests of cotton is the red
cotton insect, also known as the cotton stainer Dysdercus cingulatus. It
attacks cotton at an early stage of growth and causes significant harm by
sucking the growing cotton bolls during harvest. Because of their extreme
mobility. It is challenging to manage with insecticidal treatments. The goal of
the current investigation was to examine the synthesis and analysis of ZnO NPs
derived from leaf extract of Azadirachta indica, Calotropis gigantea and
Ricinus communis. XRD and FESEM were used to characterize the ZnO NPs.
The nymphicidal impact of different concentration of green produced ZnO NPs was
assessed against Dysdercus cingulatus, a significant pest for the cotton
industry. Each of the studied concentrations (125, 250 and 500) successfully
produced spectrum of nymphal mortality. It is concluded that ZnO NPs can be
biologically synthesized very quickly, easily, affordably, environmentally and
without any side effects and also it has the nymphicidal effect on Cotton pest.
