In vitro antibacterial activity of Vernonia amygdalin a leaves extracts against pathogen of heart rot disease

Heart rot disease is one of the major diseases in pineapple cultivation in Malaysia. Josapine and N36 are among varieties that vulnerable to the heart rot disease. The infection can reduce up to 50% yield. In vitro antibacterial activity of four Vernonia amygdalina leaves extract (hexane, chlorof...
