摘要
0 引言茭白(Zizania latifolia)为禾本科菰属多年生宿根草本植物[1],距今已有近千年的栽培历史。由于茭白营养丰富,深受消费者喜爱,逐渐成为我国除莲藕外的第二大水生类蔬菜。其较高的经济价值,亦成为我国农村经济收入的重要来源[2]。随着市场需求量增大,茭白的种植面积也逐渐扩大,连片的机械化作业导致茭白的病害面积扩散,使得茭白的病害日趋严重与多样化,严重影响了茭白的产量与质量,阻碍了茭白产业的发展扩大。
In the autumn of 2019,a new leaf spot disease was discovered on Zizania latifolia plants in two locations,Langya in Jinhua,and Daji in Lishui,Zhejiang Province.We isolated the pathogen using tissue separation method,and identified it as Epicoccum sorghinum through multiple methods,including morphological observation,biological identification and pathogenicity test.Besides,to prevent the effect of E.sorghinum on the yield and quality of Z.latifolia,12 chemical fungicides were screened.Among these,prochloraz showed the best inhibitory effect on the pathogen.Additionally it had the least side effect on the growth of Ustilago esculenta,another mutually beneficial organism associated with Z.latifolia.So prochloraz can be used as an effective fungicide for the disease management.This study provides a scientific basis for the identification and understanding the leaf spot disease in Z.latifolia.It offers insights into the selection of chemical fungicides for its control,which is valuable for agricultural and disease management.
