Abstract:

Transformation and Utilization,College of Life Science and Technology,Hubei Engineering University,Xiaogan,Hubei 432000；2.College of Forestry,Southwest Forestry University,Kunming,Yunnan 650224 With Reineckea carnea leaf spot disease as research object,the biological characteristics and suitable fungicide for the pathogen of Reineckea carnealeaf spot were investigated in this paper,in order to provide a scientific basis for the disease control.The results indicated that the pathogen mycelium were grown well in PDA under 28℃,the lethal temperature was 50℃.It could be growth in pH 4.0~10.0,and prefer to pH 6.0.The light-dark alternation（24 h/0 h）was benefit for the mycelial growth.Among the 3 tested pesticides,the most effective was 10% myclobutanil,the relative inhibition rate was 91.4% under the recommended concentration 0.3 mg/L.Lime sulfur was the least effective,the relative inhibition rate was 8.0% under the recommended concentration 6.67 mg/L.
