Diversity of endophytic bacteria in cocoa pod and their antagonistic activity against Phytophora palmivora / Noramizan Mohd Bakhir

Theobroma cocoa L. is the most important species of the genus Theobroma as they speak economically in which cultured in tropical regions. However, cocoa is affected by several diseases, such as P. palmivora black pod rot and it is also give a serious major problem in world where cocoa be planted. Th...
