used to both increase root piece number and to promote sprouting from the distal end of the root. This practice increases the risk of rot by providing an entry point for pathogens, typically soft rot ( Rhizopus sp.) ( Bouwkamp et al., 1971 ). 4

The oomycete Phytophthora capsici is a soilborne pathogen that causes severe and even complete yield loss in pepper worldwide ( Lamour et al., 2012 ). In Brazil, pepper root rot caused by P. capsici was observed for the first time in 1952 in São
