6种杀菌剂对3种禾草病害的防治研究
Control efficacy of 6 fungicides against 3 pathogens of turfgrass diseases
摘要
Abstract
Virulence determination on three pathogens of grass diseases and field trials with six fungicides were carried out.The EC50 of benomyl to Rhizoctonia solani and Colletotrichum gloeosporioides were 0.492 4 and 0.446 6 mg/L,respectively.The EC50 of carbendazim to Rhynchosporium secalis was 0.413 0 mg/L.Carbendazim had the highest toxicity of the fungicides to Rhynchosporium secalis.The field control efficacy of 50% benomyl against Rhizoctonia solani and Colletotrichum gloeosporioides of turfgrass was 75.40 % and 72.06 %,respectively,while the control efficacy of 25% carbendazim on Rhynchosporium secalis was 76.97%.关键词
