摘　　要：[Objective] Pathogen identification and disease regularity of perennial ryegrass rust in Jurong area of Jiangsu Province was conducted.[Method] Perennial ryegrass rust occurred in Science and Technology Demonstration and lawn greening band of campus in Jiangsu Polytechnic College of Agriculture and Forestry in Jurong region of Jiangsu Province were randomly investigated and their incidence laws were observed.[Result] Perennial ryegrass rust had the most serious occurrence in June each year in Jurong area of Jiangsu Province,the tender perennial ryegrass sowed this year were more susceptible to the disease than the perennial ryegrass with two years generation;Puccinia coronata var.coronata Corda was confirmed to be the pathogen of perennial ryegrass rust;when the temperature was about 25 ℃,it was the best condition for the occurrence of rust disease,when the temperature was over 35 ℃,the disease would reduce or stop.[Conclusion] Perennial ryegrass rust was first reported in Jiangsu Province.[Objective] Pathogen identification and disease regularity of perennial ryegrass rust in Jurong area of Jiangsu Province was conducted.[Method] Perennial ryegrass rust occurred in Science and Technology Demonstration and lawn greening band of campus in Jiangsu Polytechnic College of Agriculture and Forestry in Jurong region of Jiangsu Province were randomly investigated and their incidence laws were observed.[Result] Perennial ryegrass rust had the most serious occurrence in June each year in Jurong area of Jiangsu Province,the tender perennial ryegrass sowed this year were more susceptible to the disease than the perennial ryegrass with two years generation;Puccinia coronata var.coronata Corda was confirmed to be the pathogen of perennial ryegrass rust;when the temperature was about 25 ℃,it was the best condition for the occurrence of rust disease,when the temperature was over 35 ℃,the disease would reduce or stop.[Conclusion] Perennial ryegrass rust was first reported in Jiangsu Province.
