The Study on the Pathogenesis and Control of Banana Vascular Wilt

This article expatiates on the advances of banana vascular wilt in many facets, such as pathogenpathogenesis and disease-resistance mechanism of banana. The studies show that Fusarium oxysporum f. sp. Cubense race 4 makes the biggest influence to the production of banana in our country; pectase and toxin are the major virulence in coursing the banana vascular wilt. Furthermore, there are some small molecular elements that take part in the pathogenesis, but all these are still for further study to confirm. Except for the contents talking above, this article also expatiates on the control status of banana vascular wilt.
