CERNA CHAVEZ, Ernesto et al. In vitro antifungal activity of nanoformulations for the control of Fusarium solani. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.2, e3076.  Epub 21-Jun-2024. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i2.3076.

The objective of the research was to evaluate the in vitro antifungal activity of two extracts, creosote bush (Larrea tridentata L.) and mustard (Sinapis alba L.), nanoformulated with silicon oxide and zinc oxide nanoparticles (200 to 400 μ globular) on the mycelial growth and sporulation of Fusarium solani, one of the plant pathogens causing vascular wilt and root rot in at least 100 economically important crops. Inhibitory concentrations and the number of conidia were determined using the poisoned media method. Data were analyzed using probit analysis, Anova, and Tukey’s test (p≤ 0.05). The results showed that mustard-only treatments have the most effective ID50 with 920.57 ppm; nevertheless, the mixture of mustard and creosote bush with SO2 presented significant results on sporulation, with a formation of 0.35 and 0.48 million conidia ml-1 for creosote bush 3% SO2 and mustard 5% SO2 compared to the control (7.78).

Palavras-chave : mycelial growth; nanoparticles; sporulation.
