Q.Dark Lumps On My Pepper Plant Stems

Zone Johannesburg, South Africa | Jeremynel added on February 12, 2023 | Answered

Hi – I’m trying to frown cayennes peppers. There are dark brown and black lumps that have formed on the stems (picture 1). With some effort I can remove them manually – the underside is pictured (picture 2). Any ideas what these are? There are ants going up and down the stems, in case that helps, though I can’t see any aphids.
