引起薯蓣根腐病(又名薯蓣红斑病)病原为一种线虫Pratylenchusdioscoreaeyang&zhao。研究(1)查明了该线虫的寄主范围、年生活史、侵染部位、侵染时期以及在土壤中的季节消长规律和存活年限。(2)此病害由种苗、土壤、粪肥传播,提出了选用无病繁殖材料、轮作倒茬、清除病残以及药剂浸种和土壤处理等经济有效的综合防治措施。
The pathogen causing root rot of Dioscorea opposita is one kind of nematode, Pratylenchus dioscoreae Yang ＆ Zhao. The hosts, annual life history, infection site, infection period, and population dynamics and survival period were examined and clarified in this research.
