Leaf spt first appeared in early June and rapidly dispersed t ther leaves thrugh rainy seasn. Disease prgress f leaf spt by Pseudcercspra vitis in plastic green huse, in the tw prvinces (Gimje and Gimchen), were investigated in Differences f Infected leaves (%) between cultivatin systems were bserved in field and plastic green huse, but there was n difference between prvinces. Micr envirnmental factrs, such as temperature and relative humidity, were crrelated with infected leaves by PROC REG prcedure f SAS (Statistical Analysis System). As a result, regressin mdel best described (R 2 =0.95 ** ) the infected leaves as a functin f the interactin f cumulated temperatures; Y (Infected leaves)= Hcum (Cumulated hur abve 20 degree) cum (Cumulated temperature abve 20 degree) Hcum (Cumulated hur abve 25 degree). A statistics mdel was shwn that cumulated hur and temperature abve specific degree were critical factr fr Pseudcercspra leaf spt n the grapevine leaves in plastic green huse.
