Evaluating the toxicity of specific pesticides and novel nanoparticle products was the aim of the study. On the Liriomyza congesta infesting broad bean crop, abamectin, Bacillus Thuringiensis, Metaflumizone, Novaluron, K Z oil, and Nerium oleander nanoparticles were made sustainably using aqueous extract and corresponding salt (sliver nitrate). The results showed that Abamectin ˃ B. Thuringiensis ˃ Metaflumizone ˃ Novaluron ˃ N. oleander AgNps ˃ K Z oil were the pesticides and extracts of silver nanoparticles that reduced the amount of L. congesta in broad bean plants. However, the widespread use of synthetic pesticides by growers has led to a number of problems, such as environmental contamination, the rise of pest resistance, and hazards to human health. According to those results, mineral oil and nanosilver extracts considerably decreased the mortality rate of L. congesta in comparison to traditional control, and they could be a financially viable alternative in next IPM campaigns to fight this pest.
