Analysis of Pathogen Community Structure and Screening of Control Agents for Hemerocallis citrine Leaf Spot Disease in Shanxi Province
摘要
Abstract
Leaf spot is one of the main diseases of Hemerocallis citrine,there are many kinds of pathogens,but no fungicides have been registered to control the disease.In order to clarify the pathogen community structure of Hemerocallis citrine leaf spot disease in Shanxi Province and effectively control the harm caused by this disease,the pathogen community structure of Hemerocallis citrine leaf spot disease of samples collected from 4 ecological regions in Shanxi Province was analyzed,and the field control effect of 25 pesticides on Hemerocallis citrine leaf spot disease.The results showed that among the four leaf spot disease samples of Hemerocallis citrine in Shanxi Province,Fusarium tricinctum had the highest isolation frequency,reaching 47.79%,and it was the dominant pathogen community of the leaf spot disease in Shanxi Province.The isolation frequency of Alternaria tenuissima was 30.63%,that of Fusarium oxysporum was 8.29%,and that of Fusarium verticillioides was 5.91%.12 chemical fungicides were during 37.91%and 62.08%,and the best ones were fludimine and Carbendazim.The control effects of tebuconazole and difenoconazole were 53.03%and 56.40%,respectively.Among 3 kinds of bacillus fungicides,including Bacillus methylotrophic,Bacillus subtilis and Bacillus polymyxa,had the best control effect,and the control effect ranged from 49.78%to 55.95%.There were significant differences in control effects among different types of pesticides,and there were also some differences among the same type.The results provide data support for the selection of chemical and biological agents for the control of Hemerocallis citrine leaf spot disease.关键词
