SYMPTOMATOLOGY, HOSTS, AND PATHOGENICITY OF Corynespora cassiicola

Abstract

Many diseases are affecting tomato fruits in the field and greenhouse. The objective of this work was to identify, to verify the symptomatology, pathogenicity and hosts of C. cassiicola causal agent of tomato fruit rot. Symptomatic tomato fruit were isolated in medium agar-water (AW). After 48 hours, the mycelia were replicated on potato-dextrose-agar (PDA) medium. The inoculation was used mycelia discs, for treatments with and without injury, in fruits of tomato, okra, bell pepper, eggplant, zucchini, and noni were present. Both treatments, confirming the aggressiveness and pathogenicity on the original host. Among the other hosts, pathogenicity was confirmed only in okra, bell pepper, and tomato, in treatments with injury only. The comparative analysis, with the descriptions of the species, allowed the identification of the isolate as C. cassiicola, as fungi causal agent of rot fruit by tomato.

Occurrence of target spot of tomato caused by <i>Corynespora cassiicola</i> in Sri Lanka

“…Conidial lengths and widths ranged from 40.16 to 279.90 µm and 6.87 to 17.3 µm, respectively. The conidia were taxonomically similar to original description of C. cassiicola (Caetano et al, 2018).…”

Effect of Treatment with Plant Lectins on Postharvest Strawberry Fruit-Rot

“…Corynespora cassiicola was recorded as a causal agent to fruit rot on tomato as original host and okra and bell pepper as other hosts. (Caetano et al, 2018). Gajbhiye and Kapadnis (2019) reported that Corynespora cassiicola causing fruit rot on pomegranate fruits in India.…”
