几种杀菌剂对莲腐败病菌的室内毒力测定
Indoor Toxicity Tests of Several Fungicides Against Fusarium oxysporum from Nelumbo nucifera
摘要
Abstract
In order to screen effective fungicides against Fusarium oxysporum from Nelumbo nucifera, the inhibitory activity of 11 fungicides and the toxicity of 9 fungicides against F.oxysporum were tested by measuring the mycelial growth rate. Results showed that 10 fungicides had significant effects on mycelia growth in the test concentration range, but quicklime+sulphur (60+3) had no obvious effect. Results also showed that fludioxonil, flusilazole, prochloraz and difenoconazole had strong inhibitory effects on the pathogen,and the value of EC50 were 0.03, 0.02, 0.80 and 1.44μg/mL, respectively;chlorothalonil, azoxystrobin and ethylicinhad relatively had secondly strong inhibitory effects, and the values of EC50 were 6.14, 7.86 and 8.97 μg/mL, respectively;while mancozeb and hymexazol had low inhibitory effects, and the values of EC50 were 20.47 and 25.61μg/mL, respectively.关键词
