Abstract

The prototypes, Rto-x+Ca(NO3)2, K-Ca, and Rto-xβ, which were extracted from spent mushroom substrate of Hericium erinaceus, strongly inhibited the growth of Ralstonia solanacearum. The control efficacies of tomato bacterial wilt by treatment with Rto-x+Ca(NO3)2, K-Ca, and Rto-xβ were 87.4~92.4%, 46.0~100%, and 65.0~91.9%, respectively. These results indicate that Rto-x+Ca(NO3)2, K-Ca, and Rto-xβ have a potential as eco-friendly antibacterial materials for the control of tomato bacterial wilt caused by R. solanacearum.
