The pathogenicity test was conducted onto healthy detached fruits of pineapple, banana, papaya, corn, jackfruit, honeydew, starfruit, mango, dragon fruit, and guava. Each selected fruit was dedicated into three treatments which were artificial inoculated with 8 mm in diameter inoculum discs of pathogen on (i) unwounded fruit skin area, (ii) wounded fruit skin area, and (iii) control (nutrient agar discs without pathogen).

The remaining fruits that did not infected by the pathogen could be used as intercropping plants in the pineapple cultivation without worry on the disease infection and spread.
