Advances in Biological Control of Tobacco Bacte-rial Wilt
Tobacco bacterial wilt was caused by Ralstonia solanacearum. It was a worldwide disease and difficult to control. Tobacco bacterial wilt mainly spread through soil and effected on to-bacco yield and quality seriously. There were a lot of researches on bacterial wilt control, but there were still many prob-lems, biological control of tobacco bac-terial wilt was a hopeful approach. Four aspects of biological control of plant bacterial wilt research were reviewed in this paper to provide guidance, including bio-control strains, avirulent bacteriocin producing strains, induced resistance and transgenic plants. Biological control of tobacco bacterial wilt need compre-hensive prevention but not only rely on a biological control factor.
