Bio efficacy of synthesised silver nanoparticles using Dicrocephala integrifolia leaf extract and their insecticidal activity

Application of nano-agricultural technology for biotic stress management: mechanisms, optimization, and future perspectives

“…31 For pests, Ag 0 NMs (35 nm, 150 mg L −1 ) prepared using Dicrocephala integrifolia extract as a reducing agent exhibited antifeedant activity against Spodoptera litura (76.9%) and Helivoverpa armigera (79.2%), and the antifeedant activity was statistically greater than that associated with the equivalent AgNO 3 , exhibiting a significant nano-effect. 32 Ag 0 NMs at 200 mg kg −1 caused 52.0% mortality of pathogenic nematodes after 3 days exposure, and the application of Ag 0 NMs showed no effect on the growth of plant and the non-pathogenic nematode. 33 Ag 0 NMs showed great efficacy for the control of crop disease and pest in the study by Ahmed et al (2020), however, the biotransformation and toxicity to non-target organisms of Ag 0 NMs in the environment is still a major concern and the life cycle analysis of Ag 0 NMs is missing.…”

“…, nematode, Spodoptera litura , and Helicoverpa armigera ). 32,70 Malandrakis et al (2020) demonstrated that 50 mg L −1 Ag 0 NMs inhibited the growth of twenty-nine Monilia fructicola field isolates by 9.9–68.0%, and were effective against Monilia fructicola isolates resistant to benzimidazole fungicides. 71 Additionally, the potential of pathogens developing resistance to Ag based NMs is reduced because Ag based NMs display multiple modes of inhibitory action against microorganisms.…”
