防治棉花黄、枯萎病要从棉花与病原菌之间的矛盾斗争,以及与环境条件的相互关系着眼。孤立地依靠寄主抗病性或防治病原,均不能彻底解决问题;忽视新棉区的保护也将使工作处于被动。例如美国从19世纪末就选育抗病品种,但是没有一个品种能够长期保持抗性,据估计,品种抗性平均只能维持8年左右。
Prevention and control of cotton yellow and wilt disease from the conflict between cotton and pathogens, as well as the relationship between environmental conditions and focus. It is impossible to completely solve the problem by relying on host disease resistance or controlling pathogens in isolation. Ignoring the protection of new cotton areas will also make the work passive. For example, the United States bred disease-resistant varieties from the late 19th century. However, none of them is resistant to long-term persistence. It is estimated that the average resistance of cultivars can only last about 8 years.
