In March 2022, sudden wilting, black root rot and death were observed on bell pepper (Capsicum annuum) plants grown in a glasshouse at Tan Ha commune, Lam Ha District, Lam Dong, Vietnam (11°44′46.5″N 108°11′45.8″E), with a disease incidence of about 10% (Figure 1).

Description
Summary:In March 2022, sudden wilting, black root rot and death were observed on bell pepper (Capsicum annuum) plants grown in a glasshouse at Tan Ha commune, Lam Ha District, Lam Dong, Vietnam (11°44′46.5″N 108°11′45.8″E), with a disease incidence of about 10% (Figure 1). The tree is rooted by Ceratocystis virescens (KC305133) Ten sixty-day-old bell pepper plants grown in a greenhouse in 10-cm-diameter pots, containing a 4:1 w/w mixture of field soil and sand, were used to confirm the pathogenicity of isolate TROC-2. Symptoms in bell pepper grown in the greenhouse seven days after artificial inoculation (control: healthy plants; TROC-2: plants inoculated with Thielaviopsis ethacetica isolate TROC-2 showing wilting, death, and root rot) Thielaviopsis paradoxa and T. ethacetica have been reported to cause rot in pineapple and cacao, trunk and bud rot in oil palm, and sett rot in sugarcane (de Beer et al., 2014; Borges et al., 2019).
