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.
