A new method for the inoculation of Phytophthora palmivora (Butler) into cacao seedlings under greenhouse conditions.

ABSTRACT:

Background

The black pod disease affects cacao plantations worldwide; it is caused by the oomycete species of the genus Phytophthora. The resistance of cacao plants to the black pod is commonly evaluated by artificial inoculation of the pathogen and the monitoring of the disease symptoms. However, it is difficult to identify resistant plants because the commonly used methods for the inoculation of the pathogens produce inconsistent results. Therefore, this study aimed to develop an efficient and reliable method to evaluate the resistance of Theobroma cacao seedlings to the infection by Phytophthora palmivora.

Results

Seedlings of different cacao genotypes were inoculated with P. palmivora under greenhouse conditions using the previously reported i
