Oil in Water Nanoemulsions Loaded with Tebuconazole for Populus Wood Protection against White- and Brown-Rot Fungi

Abstract

Eugenol in water nanoemulsions loaded with tebuconazole appear as a very promising alternative formulations for wood protection against xylophagous fungi that are the main species responsible for different rots in wood structures. The dispersions as prepared and upon dilution (impregnation mixtures) were characterized by the apparent hydrodynamic diameter distribution of the oil droplets loaded with tebuconazole and their long-term stability. The impregnation mixtures were applied on wood of Populus canadensis I-214 clone by using a pressure-vacuum system, and the effectiveness against fungal degradation by Gloeophyllum sepiarium and Pycnoporus sanguineus fungi was determined. The retention of tebuconazole in wood was about 40% of the amount contained in the impregnation mixtures. The results showed that the impregnation process leads to a long-term antifungal protection to the wood, with the mass loss after 16 weeks being reduced more than 10 times in relation to the control (untreated poplar wood) and the reference wood (untreated beech wood).

Essential Oils and Their Individual Components in Cosmetic Products

“…On the other side, the encapsulation process is selected in such a way that can be reproducible, fast, effective, and scalable to an industrial process. Furthermore, the nature of the encapsulated compounds as well as their final application plays a very important role on the design of the encapsulation process [199][200][201][202][203].…”

“…Additionally, such a system may reduce the leaching of toxic biocides into the environment (Treu et al, 2004). The possible synergistic effect of dual treatments combining various biocides and oils on wood decay, biocide leaching and water repellency has been reported in number of studies (Palanti and Susco 2004;Lyon et al 2007;Temiz et al 2008a;Podgorski et al 2008;Tomak et al 2011a, b;Panov and Terziev, 2015;Can and Sivrikaya, 2017;Can et al, 2018;Demirel et al, 2018Demirel et al, , 2021Babar et al, 2021;Lucia et al, 2021).…”
