- Abstract:
- Nanometer cuprous oxide preparation of uniform particle size,good dispersion,the use of nanomaterials have the surface activity,small size effect and other physical properties kill fungi.In order to understand the antibacterial effect of nano Cu2O on cucumber downy mildew,the experiment adopted nano Cu2O aqueous suspension 1 000 mg·L-1,nano Cu2O aqueous suspension 500 mg·L-1,chlorothalonil 75% WP 800 times,clear water blank to deal with cucumber downy mildew pot efficacy test.The results showed that the control effect of 1 000 mg·L-1 nano Cu2O aqueous suspension was better than that of the conventional one.The nano Cu2O aqueous suspension could be used in the control of cucumber downy mildew.
