Abstract

Sclerotinia sclerotiorum is a phytopathogenic fungus that causes the disease known as cotton rot that infects crops of agronomic interest. The objective of this study was to evaluate the antifungal activity of the aqueous extract of Argemone mexicana L. commonly known as chicalote against Sclerotinia sclerotiorum, the extract was obtained from the leaves of chicalote and three concentrations were tested: 500, 1000, 2000 ppm, using the dilution method of the extract in agar, in addition the mean lethal concentration (LC₅₀) of the extract was determined by means of a Probit analysis. The 2000 ppm concentration presented the highest percentage of inhibition (27.24 ± 0.01%, Tukey P ≤ 0.05) and an LC₅₀ of 33,515 ppm. This result suggests the use of the aqueous extract of A. mexicana L. as a preventive alternative for the control of Sclerotinia sclerotiorum.
