切花菊白绢病发生规律及防治研究

Occurrence Regularity and Control of Chrysanthemum moriforlium Southern Blight

经过3年对切花菊白绢病的发生规律调查,发现白绢病在浙江的发生期为5~9月份,7~8月份高温多雨条件下发病严重,极易造成暴发流行成灾。而土壤带菌、气候条件,栽培管理与种植密度是发病的主要因素,提出了以农业防治为主、化学药剂防治为辅的综合防治措施。

After a three-year investigation of the occurrence of southern blight in Chrysanthemum moriforlium,it was found that the incidence of southern blight in Zhejiang was from May to September,and the southern blight was severe under high temperature and rain conditions from July to August,which is very likely to cause outbreaks.Soil carrier,climatic conditions,cultivation management and planting density are the main factors of disease incidence,and comprehensive prevention and control measures are proposed,which were mainly based on agricultural control and supplemented by chemical control.
