Conteúdo: 	The properties of endopolygalacturonase and pectate lyase, produced by Aternaria alternata isolated from soot mold infected Citrus trees were studied. These enzymes, related to plant pathogenesis, were obtained from supernatants from liquid Mandels nedium inoculated with fungal conidia which contained Citrus pectin as the sole carbon source. The behavior of the enzymes towards metal ions, foliar fertilizer and fungicides, was analyzed. Also, the effect of temperature was tested. Results show that at the suggested concentrations to be used at the field level for foliar nutrients and fungicides, these enzymes maintain enough activity to produce damage on the  plant tissues. Also, the high concentrations of metal ions or at different temperatures could relate to the behavior of these enzymes in these enzymes in the infection process of plant tissues in field conditions.
