From: A residue-free green synergistic antifungal nanotechnology for pesticide thiram by ZnO nanoparticles
Oxidative stress study of ZnO and ZnO-thiram treated samples.
(a): Effect of antioxditant histidine on antifungal activity of 1.0 g/L ZnO, 1.0 g/L ZnO with 0.0025 g/L thiram, 0.0025 g/L thiram. Reductions of antifungal activities were 24% and 13% respectively for ZnO and ZnO-thiram samples. However, no protective effect was observed in thiram sample. (b): SOD activities of fungi cells in the presence of 0.0025 g/L thiram, 1.0 g/L ZnO and 1.0 g/L ZnO with 0.0025 g/L thiram. It shows ZnO-thiram treated sample exhibits a higher SOD activity than ZnO treated alone. The above two test suggest the ZnO-induced oxidative damage were enhanced by thiram. Error bars are standard errors with n = 3.
