Soft-rot of ginger (Zingiber officinale) is the most important disease usually caused by Fusarium oxysporum (F. oxysporum) leading to significant yield loss. In this study, chitosan, copper and sulphur nanoparticles synthesised from leaf extract of selected plants were screened against two isolates of F. oxysporum recovered from the infected rhizome of ginger and soil samples. Moreover, among these, sulphur nanoparticles showed maximum inhibition of F. oxysporum isolated from soil samples (ZOI = 12.33 mm) followed by copper (ZOI = >12 mm) and chitosan nanoparticles (ZOI = >9 mm). Similarly, in the case of F. oxysporum isolated from infected ginger, sulphur nanoparticles showed maximum inhibition (ZOI = 13.33) as compared to copper (ZOI = >11 mm) and chitosan nanoparticles (ZOI = >9 mm). Considering the high efficacy, sulphur nanoparticles were further evaluated in combination with commercial fungicides, viz., bavistin, ridomil gold, sunflex and streptocycline. The combination of sulphur nanoparticles with bavistin demonstrated maximum inhibition (ZOI = 45.16 mm, MIC −20 µg/ml), whereas the minimum inhibition was shown by its combination with ridomil gold (ZOI = 10.5 mm, MIC-40 µg/ml). Therefore, it can be concluded that the combination of sulphur nanoparticles with bavistin can be used for effective and eco-friendly management of F. oxysporum causing soft-rot of ginger. 2 Materials and methods 2.1 Materials Leaves of two plants, viz., Hibiscus rosa-sinensis (H. rosasinensis) and Citrus medica (C. medica) used for the synthesis of nanoparticles were collected from the

“…Because of the smaller size and shape of NPs, the uptake of nutrients from the soil increases, leading to better surface area and increased photosynthesis, and finally enhanced the growth of the plants. Similarly, previous studies reported that NPs showed better growth performance in various crops such as carbon nanotubes (CNTs) in B. juncea [ 25 ], Zn, Fe, Cu NPs in Vigna radiata [ 26 ] , ZnO NPs in C. arietinum [ 27 ], Ag NPs in T. aestivum [ 28 ] and in Trigonella foenum-graecum [ 29 ], ZnO NPs and Fe 2 O 3 NPs in T. aestivum [ 30 ], CuO NPs in C. cajan [ 31 ], and TiO 2 NPs in A. thaliana [ 32 ].…”

The use of nanoparticles (NPs) in agricultural fields has risen to a level where people are considering NPs as an alternative to commercial fertilizers. The input of copper oxide NPs (CuO NPs) as seed primers was investigated in this study, and the growth indices of Brassica juncea such as phenotypic parameters, photosynthetic attributes, and biochemical parameters were measured during maximum vegetative growth stage, i.e., at 45 days after sowing. Surface sterilized seeds were soaked in varying concentrations (0, 2, 4, 8 and 16 mg/L) of CuO NPs for 15, 30, and/or 45 min. After those priming periods, the seeds were planted in pots and allowed to grow naturally. Among the different tested concentrations of CuO NPs, 4 mg/L of CuO NPs for 30 min seed priming proved to be best, and considerably increased the, shoot length (30%), root length (27%), net photosynthetic rate (30%), internal CO2 concentration (28%), and proline content (41%). Besides, the performance of the antioxidant enzymes, viz, superoxide dismutase, catalase, peroxidase, and biochemical parameters such as nitrate reductase and carbonic anhydrase were also increased by several folds after the application of CuO NPs in B. juncea. The present study suggests that CuO NPs can be effectively used to increase the performance of B. juncea and may also be suitable for testing on other crop species.

“…For example, carbon nanofibers (CNFs) were used successfully as a carrier and/or delivery agents for microelements (Cu, Fe, Zn) and the bioactive AHL molecules in rhizosphere and to the plants, without showing any potential adverse effects. ,− Most importantly, CNFs protect the AHL molecules from the enzymatic and environmental degradation in rhizosphere. Copper NPs have been shown as a potential nanobiofertilizer in combination with P. indica that enhances the growth and productivity of Cajanus cajan plant .

In the current study, we have developed a lightweight nanocomposite biofertilizer (NCB) consisting of a physical mixture of acylated homoserine lactone (AHL)-coated Fe-carbon nanofibers (Fe-CNFs) and bacterial (Panebacillus polymyxa) endospores immobilized in activated carbon beads. AHL/Fe-CNF is translocated to plants via apoplastic movement through roots to shoots and leaves, while the endospores are retained in soil, augmenting plant growth via siderophore and indole acetic acid production. We tested NCB on the leguminous (Cicer arietinum) and nonleguminous (Triticum aestivum) plants to corroborate its broad range applicability. The results show that plants grown for 30 days after supplementing NCB had a significant (p < 0.05) increase in biomass, root length, and chlorophyll as well as protein contents. In addition, the plants grown using NCB for 21 days developed a significant (p < 0.05) potential to resist Fusarium wilt of chickpea and root rot of wheat caused by Fusarium oxysporum f. sp. Cicero and Cochliobolus sativus, respectively. Overall, the developed material showed promising applicability in the plant growthpromoting activities and protection from common fungal disease in tested plant varieties.
