The development of functional nanomaterials exhibiting cost-effectiveness, biocompatibility and biodegradability in the form of nanoadditives, nanofertilizers, nanosensors, nanopesticides and herbicides, etc., has attracted considerable attention in the field of agriculture. Such nanomaterials have demonstrated the ability to increase crop production, enable the efficient and targeted delivery of agrochemicals and nutrients, enhance plant resistance to various stress factors and act as nanosensors for the detection of various pollutants, plant diseases and insufficient plant nutrition. Among others, functional magnetic nanomaterials based on iron, iron oxide, cobalt, cobalt and nickel ferrite nanoparticles, etc., are currently being investigated in agricultural applications due to their unique and tunable magnetic properties, the existing versatility with regard to their (bio)functionalization, and in some cases, their inherent ability to increase crop yield. This review article provides an up-to-date appraisal of functionalized magnetic nanomaterials being explored in the agricultural sector.

Nanotechnology research is emerging as a cuttingedge technology, and nanocomposites have played a significant role in pest control. Therefore, the present study focuses on the synthesis of tungsten oxide (WO 3 ), iron oxide (magnetic nanoparticle, MNP), and copper-doped iron oxide (MNP-Cu) nanocomposites and explores the different effects of their binary combinations with the insecticide cyromazine against Spodoptera littoralis. The synthesized nanoparticles were characterized by transmission electron microscopy, X-ray diffraction, Fouriertransform infrared spectroscopy, and Raman spectroscopy. None of the tested nanomaterials showed any toxicity against the different stages of S. littoralis. Larval and pupal durations increased with increasing cyromazine and nanomaterial concentrations. The longest larval and pupal durations were recorded under treatment with the mixture of cyromazine (100 mg/L) + MNP-Cu (500 mg/ L); the survival periods were 23.5 and 15.6 days, compared with 10.8 and 7.7 days in the control, respectively. The percentages of pupation and adult emergence were negatively affected by all treatments. Among the 500 mg/L nanomaterial combinations, only cyromazine (25 mg/L) and WO 3 (500 mg/L) resulted in adult emergence (at a rate of 27.3%). Some abnormalities in the S. littoralis stages were observed following treatment with the tested materials. The glutathione S-transferase and alpha-esterase enzyme activities in S. littoralis were significantly increased after treatment with cyromazine, followed by cyromazine/MNP-Cu combinations. The quantitative polymerase chain reaction (Q-PCR) data showed that all treated insects had a higher immune response than the control. Finally, mixes of nanocomposites and cyromazine may be suggested as viable alternatives for S. littoralis management.

Excessive application of pesticides leads to contamination of the environment, which entails the necessity to seek solutions that employ substances which do not pose ecological hazards. So, the present study was conducted to explore the different effects of tungsten oxide (WRT), magnetic nanoparticles (MNPs), Cu-doped magnetic nanoparticles (MNP-Cu), the insecticide, cyromazine, and their binary mixtures against Spodoptera littoralis. The nanomaterials individually didn’t show any toxicity against S. littoralis stages. Cyromazine recorded the highest toxicity with LC50 values of 58.7, 45.6, and 70.5 mgL− 1 against eggs, 2nd, and 4th larvae, respectively. Nanoparticles showed an antagonistic effect which increased directly with concentrations. Cyromazine (100 mgL− 1) + MNP-Cu (500 mgL− 1) was the most repellent mixture for the 2nd and 4th larvae with feeding deterrence percent, 41.42% and 57.60%, respectively. Larval and pupal durations increased with increasing cyromazine and nanomaterial concentrations. Except for the cyromazine (25 mgL− 1) + WRT (500 mgL− 1) mixture, which recorded 27.3% adult emergence, no adult emergence was recorded by the 500 mgL− 1 nanomaterial mixtures. Some malformations were also recorded for S. littoralis stages after being treated with tested materials. Cyromazine/MNP-Cu mixtures gave the highest significantly increased in the enzyme activity of glutathione S-transferase and α-esterase compared to the control. Regarding the results obtained by the Q-PCR, the insect immune response for the treatments indicated a high immune response in all the treated insects compared to the control. In conclusion, the nanomaterial-cyromazine mixtures may be recommended as promising alternatives for S. littoralis control.
