Background Nanopesticides are considered promising strategy in pest control. So, this strategy became an important new approach in pesticide formulations production. In this study, three traditional pesticide formulations (chlorfenapyr, imidacloprid and indoxacarb) were developed into nanoformulations. The toxicity of these nanoformulations was evaluated against the adults of the conical snail, Cochlicella acuta (Müller, 1774), and the chocolate banded snail, Massylaea vermiculata (Mohamed and Ali, Anim Biol J 2(4):171–180, 2011). Results The results revealed that the nanosizes of nanoformulation nanoparticles were ranged between 220 and 534 nm. The loading capacities of the selected pesticides on polymer were 65.3 ± 6.4, 62.8 ± 5.3 and 37.1 ± 0.4%for nanochlorfenapyr, nanoimidacloprid and nanoindoxacarb, respectively. The nanochlorfenapyr was the most toxic against both the C. acuta and M. vermiculata followed by nanoindoxacarb and nanoimidacloprid. The LC50,s of the nanoformulations were 6.1, 7.7 and 14.9 ppm for chlorfenapyr, indoxacarb and imidacloprid, respectively. Conclusions These results cleared that the conical snails were more susceptible to all the tested pesticides than the chocolate banded snail, M. vermiculata. The efficacy of nanochlorfenapyr, nanoindoxacarb and nanoimidacloprid on conical snails (6.1, 7.7 and 14.9 ppm, respectively) was about fourfold compared with M. vermiculata (23.1, 31.9 and 60.6 ppm, respectively).The results also revealed that the potency of nanoformulation used was not only by direct killing of tested snails but also by repellent effect.

“…Despite the fact that Si-based materials are occasionally applied in sustainable agriculture [93][94][95], there were published works on their toxic effects on microorganisms [96,97], mainly in the nanoparticles range. However, our mesoporous biosilica is relatively accessible, not harmful to the soil environment [94], and did not negatively affect the developing stages of the epigeic communities, which are intimately tied to the soil system.…”

In environmental and agronomic settings, even minor imbalances can trigger a range of unpredicted responses. Despite the widespread use of metal-based nanoparticles (NPs) and new bio-nanofertilizers, their impact on crop production is absent in the literature. Therefore, our research is focused on the agronomic effect of spray application of gold nanoparticles anchored to SiO2 mesoporous silica (AuSi-NPs), zinc oxide nanoparticles (ZnO-NPs), and iron oxide nanoparticles (Fe3O4-NPs) on sunflowers under real-world environments. Our findings revealed that the biosynthetically prepared AuSi-NPs and ZnO-NPs were highly effective in enhancing sunflower seasonal physiology, e.g., the value of the NDVI index increased from 0.012 to 0.025 after AuSi-NPs application. The distribution of leaf trichomes improved and the grain yield increased from 2.47 t ha−1 to 3.29 t ha−1 after ZnO-NPs application. AuSi-NPs treatment resulted in a higher content of essential linoleic acid (54.37%) when compared to the NPs-free control (51.57%), which had a higher determined oleic acid. No NPs or residual translocated metals were detected in the fully ripe sunflower seeds, except for slightly higher silica content after the AuSi-NPs treatment. Additionally, AuSi-NPs and NPs-free control showed wide insect biodiversity while ZnO-NPs treatment had the lowest value of phosphorus as anti-nutrient. Contradictory but insignificant effect on physiology, yield, and insect biodiversity was observed in Fe3O4-NPs treatment. Therefore, further studies are needed to fully understand the long-term environmental and agricultural sustainability of NPs applications.

The continuous use of pesticides can cause many serious problems in the environmental system. So, it is very necessary to go back to nature again and look for safe alternatives to chemical pesticides. During this research, we evaluated the toxicity of two types of natural substances (wood vinegar and seaweed extract) against three types of zoological pests, two-spotted spider mites (Tetranychus urticae) and two land snails (Monacha cartusiana and Eobania vermiculata). Results indicated that wood vinegar and seaweed extract had negative effects on eggs, immature stages and adults of T. urticae. Their mortalities were significantly increased with increasing of the applied dose of wood vinegar and seaweed extract. The highest mortalities of eggs, immature stages and adults of T. urticae were 82.9, 71.8 and 98.4% and were 75.3, 62.9 and 83.9% after 72 h from the application of wood vinegar and seaweed extract, respectively. Data showed also a positive relationship between the mortality percentages of snails and the concentration. The highest mortality rates for M. cartusiana and E. vermiculata (73.91 and 60.87%) and (91.67 and 83.33%) were recorded due to the use of wood vinegar and seaweed extract at the concentration of 25% individually. The values of LC50 and LC90 were calculated and the results confirmed that the seaweed extract was more toxic for the tested land snails than wood vinegar. The higher values of LC50 of wood vinegar and seaweed extract (21.67% and 11.87%) were selected for the biosafety tests in mammals by using Rattus norvegicus albinus males. It was clear that both wood vinegar and seaweed extract had no harmful effects on mammals according to the non-significant differences in liver and kidney functions (ALP, AST, ALT, Creatinine and urea in the blood samples) between treated and untreated rats.
