Abstract:: In order to compare the effect of Cu2O Nanoparticles and Cu2O ultrafine powder on Alternaria solani.The bacteria-inhabiting experiment to the early blight fungus with both original powder and powder suspension by adopting the drug-containing medium was condacted to test toxicity.The results showed that the inhibitory activities of Cu2O nanoparticles and Cu2O ultrafine powder to early blight fungus of tomatoes were very striking and proved a positive correlation between the degree and mass concentration of the powder in the drug-containing medium.The inhibitory activities of nanoparticles and Cu2O ultrafine powder suspension was superior to that of Cu2O powder and Cu2O ultrafine powder.The inhibitory activities of Cu2O to tomatoes depended on the particle content in the powder and the disperse stability of the powder in the medium.
