“…The biostimulant effect by both ACE and cyanobacteriumbased Ag-NPs on faba bean growth parameters is possibly due to micronutrients and many organic compounds such as auxins, gibberellins, and precursor of ethylene and betaine produced by algal cells [56]. In this context, green synthesized Ag-NPs had no plant phototoxicity when they were used to control the nematodal infection by M. javanica [57]. Further investigations are still needed to separate and purify of cyanobacterium-based Ag-NPs from the suspension mixture with AgNO 3 .…”

Background: Cyanobacterium-based silver nanoparticles are considered not only as an efficient nano-nematicide but also as a bio-stimulant material for plant growth. They could be employed as a part of an integrated program for controlling some plant diseases. Results: In this study, silver nanoparticles (Ag-NPs) were biosynthesized from aqueous extract of the cyanobacterium, Nostoc sp. PCC7524. Full characterization of the biosynthesized Ag-NPs was monitored by UV-vis spectroscopy, transmission electron microscopy, X-ray diffraction pattern, Zeta sizer, and Fourier transform infrared spectroscopy. In vitro assay against the root-knot nematode Meloidogyne javanica showed that Ag-NPs significantly decreased egg hatching of M. javanica at different applied concentrations (3, 6, 12, 25, and 50%, v/v). Fifty percent of Ag-NPs induced the highest reduction percent (94.66%). Moreover, Ag-NPs and AgNO 3 significantly increased the percentages of larval mortality of the second-stage juveniles (J 2) with concentration and time-dependent responses. Ag-NPs or AgNO 3 at 2.4 ml/l, 24 h, completely inhibited the growth of J 2 compared to 23% inhibition using aqueous cyanobacterial extract (ACE). In vivo effect of Ag-NPs on faba bean-infected plant under greenhouse conditions was achieved by treating soil with three different concentrations of 1, 2, and 3 ml/kg soil over two consecutive seasons. Ag-NPs significantly reduced root galling from 39.6 to 78.7% and J 2 population in the soils from 32.2% to 86.7% in the 2018 season and from 21.9 to 78.1% and 40.0 to 81.0% in the 2019 season, respectively. Moreover, 3 ml/kg soil of Ag-NP treatment showed statistically comparable effects to that of vydate nematicide but with remarkable enhancement of faba bean growth parameters as compared to those of vydate or AgNO 3 treatments in the two seasons. Conclusions: The considerable in vitro and in vivo nematicidal potential of the cyanobacterium-based Ag-NPs, besides their bio-stimulant effect on plant growth, makes them feasible for the biological control of M. javanica.

“…Silver ion (Ag + ) and its compounds are highly toxic to microorganisms, exhibiting strong biocidal effects on many species of bacteria and fungi ( Park et al, 2006 ; Kim et al, 2007 ; Lara et al, 2011 ). Recently, Ag nanoparticles (AgNP) have shown evidence of being a potentially effective nematicide ( Cromwell et al, 2014 ; Abdellatif et al, 2016 ; Hassan et al, 2016 ; Nassar, 2016 ; Taha, 2016 ).…”

“…The first report on the bio-efficacy of AgNP on a plant-parasitic nematode was provided by Cromwell et al (2014) against root-knot nematode on bermuda grass with mixed results, the lab assays revealed promising results but field experiments were not conclusive. Subsequent studies have explicitly revealed promising results of AgNP ( Abdellatif et al, 2016 ; Hassan et al, 2016 ) and FeNP ( Sharma et al, 2017 ) against Meloidogyne incognita on eggplant, tomato, and okra. The results were similar to fenamiphos and oxamyl at 0.003 ml/kg soil ( Hassan et al, 2016 ).…”

Plant-parasitic nematodes cause severe damage to the various agricultural crops, leading to economic losses for farmers. Therefore, identification and development of novel and environmentally benign nematicides is critically important. In this study, a silver nanoparticle (AgNP) formulation was synthesized, characterized, and investigated as a potential nematicide against rice root-knot nematode, Meloidogyne gramnicola, on rice (Oryza sativa). A series of lab assays (water and sand screening) and glasshouse experiments (using soilless system, autoclaved soil, and naturally infested soil) were conducted to examine the nematicidal effects of AgNP. The results from lab assays revealed 0.1 µg/ml as the minimum concentration for 100% irreversible nematode mortality after 12 hr in the water screening test. However, results from the sand screening test indicated 100% nematicidal effect of AgNP at 2 µg/ml after 24 hr of incubation. In glasshouse assays in soilless system of rice cultivation, 1 µg/ml concentration of AgNP applied directly to the trays achieved significant suppression of root gall formation. The effective dosage to kill nematodes in field soil assays was determined to be 3 µg/ml, which is lower than the value of 150 µg/ml reported in the literature. No visible adverse effect of AgNP was observed on seed germination or plant growth in all the experiments. The results indicate that AgNP has effective nematicidal activity against M. graminicola in rice.

“…Ardakani et al, 2016 studied effectiveness of AgNPs on M. incognita in case of tomato plants, dose of 800,400 and 200 mg/ml-1 of AgNP were highly significant to immobility and to mortality of J2 M. incognita and Ti02 nanoparticles showed 4.3 percent and 2 percent mortality when applied 800 and 400 mg/ ml-1 concentration. Abdellatif et al, 2016 studied the influence of silver nanoparticles on M. javanica reproduction and growth. They have observed that AgNPs treatment was equally effective as chemical treatment (Vydate 24%L), resulted in a reduction of egg-masses number per root system.…”

10The plant parasitic nematodes are one of world major agricultural pest, causing in excess of 157 billion dollars 11 in worldwide damage annually. This study has provided evidence that gold nanoparticles have great utility for 12 management of root-knot nematodes in tomato crop. The effect of gold nanoparticles on Meloidogyne incognita 13 J2 was remarkable under the direct exposure in water, after three hours of incubation of Meloidogyne incognita 14 with GNPs showed the 100% mortality. The lesser survival rate of Meloidogyne incognita in soil treatment 15 showed the strong nematicidal effect of gold nanoparticles. Subsequently, the pot experiment had shown the 16 beneficial effects of gold nanoparticles for intensively managing the root-knot nematode. The Pot experiment 17 not only showed us that GNPs were lethal to root-knot nematodes were also induces growth of tomato plants 18 and didn't have any kind of negative impact on plant growth. In our study, GNPs were found to be safe and 19 lethal to Meloidogyne incognita. 20 Keywords 21 Meloidogyne incognita, Gold nanoparticles, Toxicity 22 33 bio-gold nanoparticles were first synthesized by (Beveridge and Murry in 1980) by Bacillus subtilis followed by 34 (Nair and Pradeep 2002), who investigated lactic acid bacteria leading to the synthesis of 20-200 nm and are 35 called nanocrystals. In the present study, a bacterial isolate Bacillus licheniformis strain GPI-2 was isolated 36 from pebbles samples of a local gold mine near Khaltunala latitude (31.21515044oN), which synthesized gold 37 nanoparticles of 20-35nm size and hexagonal as well spherical shape. This study was undertaken to evaluate the 38 efficiency of gold nanoparticles synthesized by Bacillus licheniformis GPI-2 to control significant plant root 39 nematode (Meloidogyne incognita). 40Meloidogyne incognita is a nematode belonging to family Heteroderidae and is commonly known as root-knot 41 nematode as it prefers to attack the root of its host plant. It has worldwide distribution and numerous hosts. 42When M. incognita attacks the roots of host plants, it sets up a feeding location, where it deforms the normal
