黄萎病是棉花生产中的最主要病害之一,广泛分布于世界各产棉国。由于该病是土壤传播的维管束病害,防治难度较大,至今尚无特效的防治药剂,只能依靠种植抗病品种为主的综合防治措施。但是,我国目前棉花品种的抗病性只能达到抗至耐病水平,致使该病在环境条件适宜时连续流行为害。 Verticillium wilt is one of the most important diseases in cotton production and widely distributed in all cotton producing countries in the world. As the disease is a soil-borne vascular disease, prevention and treatment is difficult, there is no effective prevention and treatment agents, can only rely on planting resistant varieties based comprehensive prevention and control measures. However, the resistance of the cotton varieties in our country can only reach the level of resistance to disease-resistant disease, which causes the disease to be continually epidemic when the environmental conditions are suitable.
