- 摘要:
- 以番茄早疫病菌为试验对象，采用含药培养基法进行毒力测定,研究了不同质量浓度的纳米Cu2O（250、500、750、1 000、1 250 mg/kg）对番茄早疫病菌的抑制作用。结果表明：纳米Cu2O对番茄早疫病菌有明显的抑制作用。不同质量浓度的纳米Cu2O对番茄早疫病菌的抑制效果不同；抑制作用与质量浓度呈正相关，毒力回归方程的相关系数达到0.98以上；纳米Cu2O对番茄早疫病菌的有效中浓度EC50为535.8 mg/kg。
- Abstract:
- Taking Alternaria solani as material，the inhibitory effects of different concentrations of Nano-cuprous oxide (Cu2O) (250，500，750，1 000，1 250 mg/kg) on Alternaria solani of tomato were studied，and drug-containing medium was used for conducting the toxicity test.The results indicated that Nano-Cu2O had significant effects on Nano-Cu2O of tomato.Different concentrations of Nano-Cu2O had different inhibitory effects on Alternaria solani of tomato；the inhibitory effect was positively correlated to concentration，and correlation coefficient was over 0.98；the EC50 was 535.8 mg/kg for Alternaria solani of tomato.
