摘要：

研究一种复合植物源杀菌剂及其对番茄叶霉病菌的抑制效果。用万寿菊根和厚朴植物的提取物来配制15%农药乳油制剂，对它的稳定性进行了分析，并用乳油对番茄叶霉病原菌进行了毒力测试。15%农药乳油在2~40 mg/ml的浓度范围内对番茄叶霉病菌的抑制率为8.2%~80.3%，其抑制中浓度EC50为12.02 mg/ml。该研究为利用万寿菊和厚朴植物研制新型生物农药提供了科学依据。

Abstract:

The aimed to research a botanical mixture fungicides and it’s inhibitory effect against Cladosporium fulvum Cke. The extract obtained from Tagetes root and Magnolia officinalis were used to prepare 15% pesticide emulsifiable concentrate. The stability of emulsifiable concentrate was analyzed, and the virulence test was conducted on Cladosporium fulvum Cke. The inhibitory rate against Magnolia officinalis1 for 15% emulsifiable concentrate at 2~40 mg/ml was 8.2%~80.3%, and it’s Median Effective Concentration EC50 was 12.02 mg/ml. This research provided scientific basis for developing new type bio-pesticide through utilizing Tagetes root and Magnolia officinalis.
