Abstract: Management with synthetic fungicides in the control of phytopathogens in viticulture can cause environmental pollution and contamination with residues in grape cluster. The objective of this study was to verify the effect of aqueous cinnamon extract on the in vitro and in vivo control of Plasmopara viticola on catalase activity on ‘Isabel Precoce’ vines. The treatments used were: aqueous cinnamon extract (ACE) at concentrations of 0.12; 0.25 and 0.50% plus 0.25% vegetable oil (VO); being the standard treatment… Show more

“…In controlling leaf spots in tomato, the aqueous extract of C. chichenensis roots reduces the speed of symptom development over time, resulting in a large difference in severity. In other greenhouse studies, an aqueous extract of Ocimum basilicum at 10% ( w / v ) reduced by 43% the calculated rate of disease caused by C. cassiicola [ 67 ]; an aqueous extract of cinnamon at 0.25% ( w / v ) reduced the severity of grapevine downy mildew caused by Plasmopara viticola by 67% [ 68 ]. Volatile metabolites from the leaves of Solanum habrochaites (LA1777) reduced the severity of the late blight of tomato caused by Phytophthora infestans EG_7 by 97% and lowered the AUDPC [ 69 ].…”

“…Then, homogenate centrifugation was done at 12,000× g for 15 min at 4 °C. The supernatant was used to determine the peroxidase (POD) [ 31 ], catalase (CAT) [ 32 ] and superoxide dismutase (SOD) [ 33 ] activity. Activity analyses of POD, CAT and SOD were performed as described previously [ 34 ].…”

“…A fresh-leaf or root sample (0.3 g) was placed in a pre-cooled pestle and mortar and ground to a fine frozen powder under liquid nitrogen, followed by homogenization in 3 mL 50 mM phosphate buffer (pH 7.8) in an ice bath. Then, homogenate centrifugation was done at 12,000× g for 15 min at 4 • C. The supernatant was used to determine the peroxidase (POD) [31], catalase (CAT) [32] and superoxide dismutase (SOD) [33] activity. Activity analyses of POD, CAT and SOD were performed as described previously [34].…”
