“…Currently, the use of biological control agents at the commercial level has some limitations, such as adaptability to biotic and abiotic factors and deterioration of the desired activity between in vitro and in vivo [2]. It is time to develop more effective and nonpersistent biopesticides with the aid of nanotechnology using biogenic silver, zinc, copper, gold, and iron [3].…”

The scientific consensus is now on developing a biocontrol agent that can cause cellular metabolic reprogramming against agricultural pathogens. Biosynthesis of silver nanoparticles was performed by using phytopathogenic fungi (Alternaria sp.) isolated from banana cultivated soil. Alternaria sp. can grow very fast and produce high enough bioactive compounds. This study aims to biosynthesize silver nanoparticles (AgNPs) using fungal Alternaria sp.’s metabolites as a safe antifungal agent against plant pathogenic fungi (Fusarium spp. and Alternaria sp.). To visualize the formation of AgNPs, analytical instruments were used, such as ultraviolet-visible (UV-Vis) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, scanning transmission electron microscopy (STEM), energy dispersive X-ray (EDX), and elemental mapping. The UV-visible spectra showed a peak at 435 nm. Analysis of scanning transmission electron microscopy (STEM) micrographs evidenced that the size of synthesized silver nanoparticles ranged between 3 and 10 nm. The resulting AgNPs showed distinct antifungal activity against selected plant pathogenic fungi. Synthesized AgNPs have demonstrated remarkable potential for the use of antifungal compounds to combat plant diseases.

There are many constraints that severely affect the global agricultural production and productivity which include the ever increasing of population growth, degradation of natural resources, climate changes and emerging pests. Among these factors, biotic constraints or pests are known to cause 25-50% or complete loss of plant production. Accordingly, various plant protection technologies have been deployed with the trend of focusing on the use modern biotechnological tools that are proven to be most effective and mandatory. The review covers a wide array of pest management methods ranging from the conventional biological control methods up to molecular breeding techniques. Furthermore, the application of new genetic engineering techniques fueled by new breakthroughs and innovations are the cornerstone of this review. Accordingly, the continuous increasing trend of GM crops cultivation in both crop type and hectare has urged many countries to deploy the technology as a key strategy to enhance their bioeconomy. In fact, plant protection is the discipline that immensely benefit from biotechnology than any other disciplines for ensuring food security and sustainable development. However, in order to fully exploit the enormous potential of biotechnology, appropriate biosafety regulatory frameworks and proper stewardship programs need to be effectively implemented. This integrated approach can promptly help respond to the ever-dynamic threat of pests and hence reliably combat food insecurity and ably contribute to sustainable development. Int. J. Appl. Sci.

Background: Biogenic nanoparticles have proved to be effective biocontrol agents for certain plant diseases. It possesses the potential for extensive use for sustainable agriculture. Many attempts have been made to synthesize nano-based antifungal compounds for the management of soil borne pathogenic fungi for crops.Results: In our work, silver nanoparticles (AgNPs) was constructed with phytopathogenic fungi (Alternaria sp.) which was isolated from banana cultivated soil. Alternaria sp. was able to grow rapidly and produce highly bioactive compounds as safe antifungal agent against plant pathogenic fungi (Fusarium spp. and Alternaria sp.). The size of synthesized silver nanoparticles ranged between 5-10 nm. Analytic tools, such as UV-visible spectroscopy, Fourier transformed infra-red (FTIR) spectroscopy, scanning transmission electron microscopy (STEM), EDS and elemental mapping were used to visualize the formation of AgNPs. The UV-visible spectra showed the peak at 435 nm. The maximum inhibition zone was observed at 100 µl concentration of AgNPs for Fusarium oxysporum (21 ± 2 mm) following Alternaria sp. (20± 2 mm), suggested that the efficacy of the biosynthesized NPs against the phytopathogenic fungi.Conclusions: The resulting AgNPs showed distinct antifungal activity against selected pathogenic plant fungi. The work indicates that green reduction and biogenic synthesis of nanoparticles with benign fungi is an effective, low cost, sustainable and environmentally friendly approach for prevention of soil borne plant diseases.
