| Summary: | The genus <i>Pycnoporus</i> includes fungi with great potential for the production of antibiotic substances. It is necessary to develop new models to assess their effectiveness against microorganisms with an economic impact, such as phytopathogenic fungi. The objective of this study is to evaluate three models of <i>Pycnoporus sanguineus</i> for the growth inhibition of the phytopathogens <i>Botrytis cinerea</i> and <i>Fusarium oxysporum</i>. Model 1 involves dual tests of the antagonistic activity of <i>P. sanguineus</i> vs. phytopathogens, Model 2 involves antifungal effectiveness tests of cinnabarin, and Model 3 involves antifungal effectiveness tests of <i>P. sanguineus</i> extract. Models 2 and 3 are contrasted with products containing benomyl and captan. The results show that Model 3 is the most effective in controlling <i>B. cinerea</i>, with an inhibition percentage of 74.34% (<i>p</i> < 0.05) and a decrease in the growth rate (3.85 mm/day; <i>p</i> < 0.05); the same is true for <i>F. oxysporum,</i> with an inhibition percentage of 47.14% (<i>p</i> < 0.05). In general, <i>F. oxysporum</i> exhibits greater resistance (<i>p</i> < 0.05). The results of this study indicate that <i>P. sanguineus</i> extracts may be used as control agents for fungal species in the same way as other <i>Pycnoporus</i> species. Although commercial products are very efficient at inhibiting phytopathogens, one must consider the disadvantages of their use. In the short term, new models involving <i>Pycnoporus</i> for biological control in food production will be developed. |
