“…Once TDS nanoparticles passed through the cell membranes of mycelia or spores, TDS can effectively inhibit the cell metabolisms, because being a vitamin B1 derivatives, TDS can strongly attach to the cell membranes and inhibit cell differentiation and proliferation in the cytosol [25]. According to this mechanism, the TDS nanoparticles inhibit cell division by attaching to the cell membranes of the mycelia or substantially inhibiting their proliferation by penetrating the protoplasm [26].…”

Nanoencapsulation of thiamine dilauryl sulfate (TDS), a vitamin B1 derivative, was proved to effectively inhibit the spore germination of Fusarium oxysporum f. sp. raphani (F. oxysporum), as well as mycelial growth. The average diameter of nanoparticles was measured as 136 nm by being encapsulated with an edible encapsulant, lecithin, whose encapsulation efficiency was about 55% in containing 200 ppm of TDS concentration: the 100 ppm TDS nanoparticle solution showed a mycelial growth inhibition rate of 59%. These results were about similar or even better than the cases of treating 100 ppm of dazomet, a positive antifungal control (64%). Moreover, kinetic analysis of inhibiting spore germination were estimated as 6.6% reduction of spore germination rates after 24 h treatment, which were 3.3% similar to the case of treating 100 ppm of a positive control (dazomet) for the same treatment time. It was also found that TDS itself could work as an antifungal agent by inhibiting both mycelial growth and spore germination, even though its efficacy was lower than those of nanoparticles. Nanoparticles especially played a more efficient role in limiting the spore germination, due to their easy penetration into hard cell membranes and long resident time on the surface of the spore shell walls. In this work, it was first demonstrated that the nanoparticle of TDS not a harmful chemical can control the growth of F. oxysporum by using a lower dosage than commercial herbicides, as well as the inhibiting mechanism of the TDS. However, field trials of the TDS nanoparticles encapsulated with lecithin should be further studied to be effectively used for field applications.

“…Nanomaterials hold great promise as a novel agrochemical regarding their application in plant protection and nutrition due to their size-dependent qualities, high surface-to-volume ratio and unique optical properties [7]. Among the nanoparticles, use of metal-based nanoparticles was widely used in crop protection [9][10][11][12][13][14][15][16]. But the possible environmental toxicity due to unpredicted nature of metal nanoparticles has raised serious questions of their application in crops [17].…”

“…Diverse studies have been conducted on oak wood, including those on anatomical, physical, mechanical, and chemical properties (Kim et al, 2006;Han et al, 2015;Kim et al, 2015;Chang et al, 2017;. On the other hand, studies on trees damaged by oak wilt disease are somewhat limited to pest control, physical, and mechanical characteristics (Kim et al, 2011;Son et al, 2014;Kim et al, 2016;Kim et al, 2020). Although there are studies on trees infected with oak wilt disease, basic anatomical data that can facilitate the utilization of the damaged tree is insufficient.…”

The aim of this study was to investigate the anatomical characteristics of Quercus mongolica infested by oak wilt disease. To analysis the anatomical characteristics of the wood specimens infested by the oak wilt, the anatomical structures of an infected wood, a dead wood, and sound wood were observed at 10-year-old intervals from 10 to 50 annual rings using both an optical and a scanning electron microscope. The fiber length was measured in units of 5 annual rings from the pith, and the diameter of the vessel element and the ratio of the vessel including the tyloses were measured for each 10 annual ring. In the cross section, on the infected and dead wood specimens, mycelium was also observed with the tyloses in the vessel. There was no signification difference between the wood specimens in the fiber length and the vessel diameter of the vessel element. The fiber length was not difference after 20-30 annual rings which is a part of juvenile wood. The average of the vessel ratio including tyloses in the infected wood was the highest. Especially, the ratio of tyloses was the highest 40-50 annual rings in the infected wood and the dead wood. Therefore, the large difference between the infested wood by oak wilt and the sound wood was the ratio of tyloses. This result can be used as a basic data to utilize the infested wood.
