Korean ginseng has been used for thousands of years as an important medicinal plant. Lime-Bordeaux mixture (LBM) was made with copper sulfate and quicklime, which was sprayed instead of pesticides in ginseng field. Net photosynthesis (PN) was compared between Treatment and Non-treatment of LBM in 3 Year Old Ginseng. PN in control plot recorded 2.94μmol (CO2) m-2s-1 at the first day of experiment, which was similar until the last day of experiment. However, The PN in LBM recorded 2.23μmol (CO2) m-2s-1, which was lower than that in control plot. As time goes by, The PN in LBM was gradually increased up to 3.21μmol (CO2) m-2s-1 and finally, it was similar with that in control plot at 7th day as a 3.20μmol (CO2) m-2s-1).
