The inhibition effect of thirteen fungicides on the germination of urediniospores of peach rust fungus were evaluated by an efficient procedure applicable in the laboratory. Leaves with urediniospores were taken from the diseased trees and sprayed with various fungicide solutions in the laboratory. The leaves were left air-dryed for 12 hours before the urediniospores were collected and subsequently spread on petri dishes with 2% water agar. Germination percentages of uredinioores were counted after incubation period of 12 hours at 16℃. Results of this investigation showed that Chlorothalonil 75% WP had the best effect to inhibit the target fungus.
