“…Moreover, Nassar (2018) reported that Azadirachta indica based ZnO-NPs exhibited a maximum zone of inhibition of 17.80 ± 4.52 mm against Sclerotium rolfsii and Rhizoctonia solani . However, there are some limitations of our study concerned with the complexity of plant components, their seasonal and geographical distribution, and low purity and yield.…”

Background The green approaches for the synthesis of nanoparticles are gaining significant importance because of their high productivity, purity, low cost, biocompatibility, and environmental friendliness. Methods The aim of the current study is the green synthesis of zinc oxide nanoparticles (ZnO-NPs) using seed extracts of Silybum marianum, which acts as a reducing and stabilizing agent. central composite design (CCD) of response surface methodology (RSM) optimized synthesis parameters (temperature, pH, reaction time, plant extract, and salt concentration) for controlled size, stability, and maximum yields of ZnO-NPs. Green synthesized ZnO-NPs was characterized using UV-visible spectroscopy and Zetasizer analyses. Results The Zetasizer confirmed that green synthesized ZnO-NPs were 51.80 nm in size and monodispersed in nature. The UV-visible results revealed a large band gap energy in the visible region at 360.5 nm wavelength. The bioactivities of green synthesized ZnO-NPs, including antifungal, antibacterial, and pesticidal, were also evaluated. Data analysis confirmed that these activities were concentration dependent. Bio-synthesized ZnO-NPs showed higher mortality towards Tribolium castaneum of about 78 ± 0.57% after 72 h observation as compared to Sitophilus oryzae, which only displayed 74 ± 0.57% at the same concentration and time intervals. Plant-mediated ZnO-NPs also showed high potential against pathogenic gram-positive bacteria (Clavibacter michiganensis), gram-negative bacteria (Pseudomonas syringae), and two fungal strains such as Fusarium oxysporum, and Aspergillums niger with inhibition zones of 18 ± 0.4, 25 ± 0.4, 21 ± 0.57, and 19 ± 0.4 mm, respectively. Conclusion The results of this study showed that Silybum marianum-based ZnO-NPs are cost-effective and efficient against crop pests.

The food industry is not the only sphere of human activity where inorganic food additives are globally used. In certain concentrations, they are safe for people and agricultural animals. Nonetheless, they impose a negative impact on other classes of living organisms. Therefore, our objective was to determinine the influence of some inorganic food additives (alkalis, acids, salts) on the vitality of nematode larvae that parasitize agricultural animals: Strongyloides papillosus, Haemonchus contortus and Muellerius capillaris. We studied the effects of sodium hydroxide, potassium hydroxide, boric acid, phosphoric acid, potassium chloride, calcium chloride, sodium nitrite, potassium nitrite, sodium nitrate, potassium nitrate, ammonium bicarbonate, sodium bisulfite, sodium bisulfate, sodium sulfate, potassium sulfate, calcium sulfate, sodium thiosulfate, sodium metabisulfite, potassium metabisulfite, copper sulfate pentahydrate, tetrasodium pyrophosphate, sodium triphosphate, sodium borate decahydrate and talc. In in vitro experiments, the strongest effects were produced by alkalis sodium hydroxide and potassium hydroxide. In 24 h, 1% solutions of those substances killed 69% of larvae of S. papillosus, H. contortus and M. capillaris of various development stages. Sodium sulfate was effective against all stages of larvae of S. papillosus, and also against first-age M. capillaris. Nematocidal properties only against all stages of S. papillosus were exerted by copper sulfate pentahydrate. Non-invasive stages of S. papillosus nematodes were affected only by phosphoric acid, ammonium bicarbonate, calcium chloride, sodium nitrite, calcium sulfate, potassium metabisulfite, tetrasodium pyrophosphate, sodium triphosphate and the same stages of M. capillaris—by phosphoric acid, sodium bisulfite and potassium nitrite.

“…Chlorfenapyr is one of the acaricides with high effective against whitefly and leafminer (Thamilarasi et al, 2016 andUdhayakumar et al, 2020), but its toxicity to human health should be considered (Joko et al, 2017). Jojoba oil is one of the organic extracts safe to humans with a good efficiency against several insect pests ( Abbassy et al 2007;Nassar et al, 2019). Thiamethoxam and imidacloprid recorded 75.0% -80% reductions in whitefly and leafminer populations (Hanumappa et al, 2013).…”

This study was conducted to evaluate nine insecticidal combinations against the whitefly Bemisia tabaci (Gennadius) and the Leafminer Liriomyza sativae (Blanchard) attacking cucumber crops in the open field during 2022 and 2023 seasons. These treatments were abamectin, abamectin with bifenthrin, chlorfenapyr, fenpropathrin with etoxazole, jojoba oil, imidacloprid, imidacloprid with abamectin, thiamethoxam and thiamethoxam with abamectin. All treatments resulted in significant reduction on both insects. Chlorfenapyr was the most effective compound against whitefly at initial effect, 5, 7, 10 days after treatments and overall average by 95.
