- Abstract
Hot chilli (Capsicum annuum), a spice crop, has been cultivated in Vietnam since the 18th century. Phytophthora disease, caused by Phytophthora capsici, is an economically important disease caused in Capsicum and many other crop species worldwide. The study of this disease is very limited in Vietnam. Phytophthora capsici was identified as the causal agent of a crown and root rot of chilli pepper in Central Vietnam. Identification of the causal agent was based on disease symptoms, morphological characteristics, and molecular analysis using ITS-RFLP. Koch's postulates were fulfilled by pathogenicity tests. Chicken manure and products derived from chicken manure were demonstrated to be effective in controlling crown and root rot of hot chilli in the greenhouse. This study provides a sound basis for developing management strategies of Phytophthora disease of chilli and other crops caused by P. capsici in Vietnam. Further studies concerning the disease cycle, the genetic diversity of the pathogen and the availability of host resistance should be required.
