The paper presents the results of four-ear trials of preparations with silver nanoparticles Zerox,Zeromiks, and Zerebra Agro on varieties with varying degrees of resistance to the main potato diseases. The four-ear trials made it possible to conclude that preparations with silver nanoparticles were effective in protecting potatoes from rhizoctoniosis and alternariosis, comparable to the effectiveness of chemical treaters (Maxim and Celeste Top) and fungicides used in the treatment of vegetative plants (Abiga Peak and Ridomil Gold MC). The biological effectiveness of preparations with silver nanoparticles was lower than that of Abig Peak by an average of 49.8% against late blight on the unstable Ilyinsky variety. The biological effectiveness of Zerebra Agro was low (24.6%) in relation to late blight on the Sante variety in the epiphytotic year. It was high (65.7%) in the non-epiphytotic year, and it was not much worse than chemical fungicides (30.4 and 78.1%, respectively) in both the epiphytotic and non-epiphytotic years.In 2018, when the effectiveness of the preparations was high for all major potato diseases,the yield increase was significantly higher than the check. In the standard version, it exceeded the check by 26.4%, in the variant with Zerebra Agro – by 27.1%. No significant difference was found between the standard variant and Zerebra Agro.

Optic Probe

Surface-enhanced Raman Scattering (SERS) fiber probe provides abundant interaction area between light and materials, permits detection within limited space and is especially useful for remote or in situ detection. A silver decorated SERS fiber optic probe was prepared by hydrothermal method. This method manages to accomplish the growth of silver nanoparticles and its adherence on fiber optic tip within one step, simplifying the synthetic procedure. The effects of reaction time on phase composition, surface plasmon resonance property and morphology were investigated by X-ray diffraction analysis (XRD), ultraviolet-visible absorption spectrum (UV-VIS absorption spectrum) and scanning electron microscope (SEM). The results showed that when reaction time is prolonged from 4–8 hours at 180 °C, crystals size and size distribution of silver nanoparticles increase. Furthermore, the morphology, crystal size and distribution density of silver nanoparticles evolve along with reaction time. A growth mechanism based on two factors, equilibrium between nucleation and growth, and the existence of PVP, is hypothesized. The SERS fiber probe can detect rhodamin 6G (R6G) at the concentration of 10−6 M. This SERS fiber probe exhibits promising potential in organic dye and pesticide residue detection.
