摘要:

【目的】研究筛选对芹菜叶斑病(病菌为:细极链格孢Alternaria tenuissima)具有良好防治作用的药剂。【方法】采用菌丝生长速率法和琼脂片法分别用14种杀菌剂对细极链格孢(A.tenuissima)菌丝和孢子萌发做室内毒力测定并进行田间药效试验。【结果】14种杀菌剂中对病原菌菌丝抑制效果最好的分别为3%甲霜恶霉灵、5%香芹酚、10%苯醚甲环唑、其EC50分别为10.8、19.9、26.2 μg/mL;对孢子萌发抑制效果最好的分别为3%甲霜恶霉灵、25%嘧菌酯、43%戊唑醇,其EC50分别为15.7、29.5、38.7 μg/mL。只有3%甲霜恶霉灵具有最佳的防治效果。防效最好的药剂为3%甲霜恶霉灵和5%香芹酚,其防效分别为96.3%和83.9%。【结论】3%甲霜恶霉灵最适用于田间芹菜叶斑病的防治。

Abstract:

【Objective】 This study aims to screen out the agents that have a good control effect on celery leaf spot (the pathogen was: Alternaria tenuissima).【Method】 The toxicity of 14 fungicides to the mycelia and spore germination of A.tenuissima were measured in laboratory and the field efficacy test was carried out.【Result】 Among the 14 fungicides, the best inhibition effect on pathogen mycelia was 3% Metalaxyl hymexazol, 5% Carvacrol, 10% difenoconazole, and the EC50 was 10.8, 19.9, 26.2 μg/mL, respectively.The best inhibition effect on spore germination was 3% Metalaxyl hymexazol, 25% Azoxystrobin, 43% Tebuconazole, and the EC50 was 15.7, 29.5, 38.7 μg/mL, respectively.The inhibition test on mycelia and spores showed that only 3% Metalaxyl hymexazol had the best control effect.And the field efficacy test verified the best control effect of the agent was 3% Metalaxyl hymexazol and 5% Carvacrol, its control effect was 96.3% and 83.9%, respectively.【Conclusion】 3% alopectyl was most suitable for the prevention and treatment of celery leaf spot in the field.
