Continuous cropping increases disease severity and causes arrested development of chilli plants the decrease yield quality. Hemp-chilli rotation evidently eased diseases, but causation remains unknown. This paper investigated index (DI) chilli’s anthracnose for hemp-chilli continuous cropping, antifungal effect water extract hemp residues, bacteria antagonistic to fungus from rhizosphere. Hemp grown as a preceding crop decreased DI 35–39% 14–15% rotation. residue executed suppression efficiency increased concentration 1% 5%. 5% gave mean inhibition ratio (IR) 32.34% spore germination IR 53.72% mycelia growth, which was much greater than that extract. Antagonistic isolated rhizosphere depressed growth with 32.35%, while no were obtained The stronger allelopathy synergistically suppressed in succeeding crop.
