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 different rots structures. The dispersions prepared and upon dilution (impregnation mixtures) were characterized by apparent hydrodynamic diameter distribution of oil droplets their long-term stability. im...
some criteria of density in beech saplings were studied in various forest associations (mainly galio odorati-fagetum typicum) growing in the submontane region near zurich (swiss central plateau). the sample plots were established in regeneration gaps resulting from swiss irregular shelter wood system (femelschlag). five sample plots, each 2x2m in 3 transects (a total of 15 plots in each gap, x ...
