1. The hair cells on adaxial surface turned out to be penetration way of Gleosporium Thea sinensis in tea plant. 2. The most parts of Gleosporium Thea sinensis generated in tea plant were young leaves with first-fifth leaves from tip of shoot. 3. The proper temperature for spore germination on leaf is $25-27^{\circ}C$, soaked by water for 12 hours. 4. For prevention of Gleosporium Thea sinensis the drug-spay in tea plant would be the most effective when sprayed at this temperature range, and the control of Gleosporium Thea sinensis would be possible through selection of tea plant with few hairs. 5. The treatment of bordeaux mixture to prevent growth of conidiospore was 48.3% more effective than in control plot which were not sprayed. 6. The effect of sprayed bordeaux mixture decreased to about 28.5% after one week of spray.
