“…Furthermore, the excess iron applied on the plants created oxidative stress on leaf cells, affecting their photosynthesis and led to a lower metabolism rate. In another experiment, Ursache-Oprisan et al [244] applied the Fe 3 O 4 NPs on sunflower (Helianthus annuus) seedlings and evaluated the chlorophyll content in them through spectral measurements. Accordingly, the Fe 3 O 4 NPs had no effect on the germination rate of sunflower seeds, but their chlorophyll content was reduced up to 50 %.…”

Iron‐based magnetic nanoparticles (MNPs) have been studied extensively for the past few decades. They have been applied in various applications, particularly in the biomedical sector. Due to their excellent physical and chemical properties, they have also been used widely in the agricultural sector. MNPs can be synthesized inexpensively and applied in large scale agricultural activities. This paper highlights the applications of iron‐based MNPs in the agricultural sector mainly as antimicrobial agents, plant growth promoters, site‐targeted delivery agents, nanosensors, detection and remediation for pesticide residue. Furthermore, the toxicity and transport of iron‐based MNPs in the soil‐plant system are also elucidated. These aspects have to be well‐understood before MNPs can be fully implemented effectively this pin the agricultural sector. Lastly, a hybrid nanomaterial, which is consisted of iron and magnesium oxide (MgO) nanoparticles (NPs), is proposed. This hybrid nanomaterial is expected to overcome the shortcomings of iron‐based MNPs.

“…211 Recent studies have shown that various nanoparticles including CeO 2 , Fe 3 O 4 , cobalt ferrite (CoFe 2 O 4 ), and TiO 2 induce ROS production in plants. 227–229 Furthermore, not only ZnO nanoparticles but also the nanoparticle-release zinc ions triggered the ROS production in A. cepa . 230 An investigation on the concentration-dependent ROS generation ability of NiO nanoparticles in tomato roots and isolated protoplast from roots has also been performed.…”

“…58 Thus, to mention only sunflower, a previous work found that NPsMagn diminished chlorophyll and carotenoid contents up to 50 % in sunflower seedlings and the combination with Pb could contribute to increase this impact. 59 Otherwise, IONPs can induce no effect 60 or increase 61 pigment contents.…”
