Pathogen Identification of Gray Mold on Scutellaria baicalensis in Gansu Province
摘要
Abstract
Objective:During disease surveys on medicinal plants in Gansu province in 2013-2016,we found that gray mold on Scutellaria baicalensis was a serious disease with 10 ~ 15% disease incidence and 2 ~ 3 level of disease severity.The study of the disease incidence and the pathogen identification will provide scientific basis to the control of the disease.Methods:The disease incidence in Gansu province was determined by field surveys.Morphological and molecular methods were combined to identify the pathogen.Results:The disease leads to leaf lesions and plant blight.The conidiophore of the causal pathogen is brown,multi septate,450.0 ~716.6 μm ×9.4 ~ 18.8 μm in size;the conidia is aseptate,colorless,ellipsoidal,8.2 ~ 16.5 μm ×5.9 ~ 8.2(mean =10.6 x 7.3) μm in size.Based on morphological characteristics and rDNA internal transcribed spacer sequence analysis the fungi is identified as Botrytis cinerea Pers.S.baicalensis gray mold appears in all the planting areas in Gansu province.Conclusion:The cultivation methods and chemical control methods should be combined to control this disease.关键词
