Notes:
The antifungal effectiveness against rose powdery mildew using antimicrobial nanosilvercolloidal solution was investigated. Double-capsulized nanosilver was prepared by chemicalreaction of silver ion with aid of physical method, reducing agent and stabilizers. The averagediameter of nanosilver was about 1.5 nm. They were highly stable and very well dispersive inaqueous solution. The Transmission electron microscopy and UV-vis spectrometer were usedfor measurements of size analysis and their stability, respectively. The nanosilver colloidalsolution of concentration of 5000 ppm was diluted in 10 ppm of 500 kg and sprayed at largearea of 3306 m2polluted by rose powdery mildew. The white rose powdery mildew fade outabove 95 % after 2 days and was not recurred for a week. The antifungal effects were observedby an optical microscope and photographs
