摘要
对芦荟斑点病进行病原鉴定，研究温度对病原菌生长和产孢的影响以及不同杀菌剂对病原菌生长的抑制效果。结果表明，芦荟斑点病是因胶孢炭疽菌（Colletotrichum gloeosporioides Penz.）侵染导致。菌丝生长的温度范围为8-38℃，最适生长温度为26-32℃；产生分生孢子的温度范围为12-38℃，最适产孢温度为28-34℃的施保功、甲基托布津对芦荟斑点病病菌丝生长的抑制作用分别为98.7％和97.6％。
In this paper the pathogen of Aloe spot disease was identified. The bacteriostatic effects of chemicals on the growth of mycelia were also studied apart from the effects of temperature on mycelia growth and sporulation. The experimental results revealed that it was Colletotrichum gloeosporioides Penz. which caused the disease; its mycelia could grow in the temperature from 8℃ to 38℃, and the range 26-32℃ was optimal; the pathogen was able to produce conidiophores from 15℃ to 35℃, but the range 30-35℃ was more suitable. The outcome of the chemical screening experiment indicated that all of the five chemicals of different concentration could restrain the mycelia growth to some extent, and Sporgon and Thiophanate-Methyl in lower concentration could control the disease effectively.
