24种杀菌剂对香葱灰霉病菌的室内毒力测定
Toxicities of 24 Fungicides on Botrytis cinerea
摘要
Abstract
Toxicities of 24 fungicides on the pathogen,Botrytis cinereal,were compared on the fungal mycelial growth under the treatments in laboratory.The study aimed for an effective control of B.cinerea on Allium ascalonicum.Among the single-ingredient fungicides in different concentrations,24％ nitrile oxazole,25％ hexaconazole,40％ pyrimethanil,50％ fludioxonil,50％ iprodione,5％ Jinggangmycin,25％ azoxystrobin,and 51％ Shenqinmycin exhibited varying degrees of antifungal activities against B.cinerea,with EC50 of 0.051 5,0.200 1,0.266 5,0.391 6,0.590 6,1.487 9,2.024 0,2.3922 mg · L-1,respectively.Whereas,the multi-ingredient fungicides in specific concentrations,such as 85％ nicotinamide/pyrimethanil/boscalid,36 ％ hymexazol/famoxadone/shenqinmycin,26％ difenoconazole/azoxystrobin,and 25％ metalaxyl/propamocarb showed EC50 of 0.269 6,0.811 8,1.185 6,9.708 4 mg · L-1,respectively.关键词
